Help needed - vibration update

[duhtroll]

Howdy y'all.

The update on my rear end vibration is a trip to the dealer today. The vibration was originally described in a thread about driveshafts. I assumed it to be a driveshaft issue since it starts at EXACTLY 80 MPH and gets worse as I go faster (I have not been much faster since discovering it obviously). It also could not be my wheels or tires as I have swapped them since discovery and it happens the same way with both sets.

Their tech's analysis today is that it is either the "front u-joint" or it could be the ring and pinion (I have 4.10s installed by their "senior master tech" and they have approximately 27K miles on them - I also had a pinion seal leak a few months ago that he fixed for free)

To the mechanics, since I am not mechanically minded and must rely on research, not experience . . .

Does this sound like a possibility? (u-joint, or worse yet, gears) The vibration is very even and definitely related to speed by its sound and by the fact it occurs only at high speeds. It has not happened until recently.

I asked if there was a way to tell whether it was the u-joint or the gears before ordering parts, and they told me there was no way. Is this correct?

If it is the gears I will be upset. I realize it's my responsibility since it's my mod, yadda yadda, so we can avoid that whole discussion. My anger will be that gears lasted only 27K and I will wonder if they weren't installed improperly on purpose to get more money out of me. I seriously doubt the parts failed.

Am I being taken for a ride?

They ordered a part for me under warranty since "we wanted to try something that wouldn't cost you any money first." (their words) However, I would bet that this is coming out of my pocket at some point.

Which is fine, if it really is my responsibility.

Any help offered is greatly appreciated.

Thanks,

I don't know much...but it's easy to check u-joint play. Typically cars with massive milage, or beatage, experience u-joint failure. The driveshaft will have excessive play, and occationally clunk when the car is shifted into gear.

I suppose gears could cause some vibrations, particularly at speed.

Let's see what some of the the real techs arounfd here have to say.

Hey Claude!!!

I can't believe a gear set would do that, and they don't wear out. If they're not installed correctly, you know it right away. Sounds to me like your service guys are treating you well. Give 'em a chance.:twocents:

[Murader03]

I've got 70K on the car. The gears have approximately 60K on them to date, one of the first mods I did after buying the car. I've had no problems with the gears at all. U-joint could be an issue, but I would think you would feel it regardless of speed. Good luck!

[Marauderjack]

I had a 2000 CV with the same symtoms...Ended up being bad axles and bearings!! :confused: I thought the ROAR was worn tires but it was the good ole "Soft" Ford axles!! :mad2: Of course I had almost 200K miles on it but I have never had rear problems before and believe me the axles were shot!! Had a groove 1/8" deep where the bearings run and the rear was full of metal!!

Check your magnetic fill plug and see how much debris is on it....should tell the story!! :o

BTW....can you feel the roaring vibration in the shaft tunnel behind the console??

[MM2004]

There have been cases where a driveshaft loses one of its correction (balance) weights for whatever reason. This will cause an out of balance condition that will worsen as the driveshaft spins faster. Easily checked by examining both ends of the driveshaft for a weight that may have detached itself. Carefully look and feel around the driveshaft ends for a broken weld on the tube. Correction weight location should be no more than approx. 5 inches from the circle weld of both ends.
Loose or worn u-joints can cause this vibration as well that typically will be felt in the seat/floor of the vehicle that can also worsen as the driveshaft spins faster.
Is the driveshaft OEM?
How many miles on the vehicle?

[merc406]

Don't drive faster than 80, problem fixed... :beer:

[duhtroll]

Marauderjack :bandit:

Nope - this is strictly felt through the "floorboards." Does that help?

[duhtroll]

I will have a look-see next time I can get under it.

I have 30K on the car, and the gears were put in at approx. 3K. Driveshaft is stock.

Duhtroll, I have the exact problem you described in this tread. Brian (FordNut) drove my car last year in Atlanta and noticed a vibration at normal driving speeds. During the summer drag events I quickly noticed the vibration as I pasted the 1/8mile mark and it continued till the end or the quarter mile. I have not changed my O.E.M drive shaft, but I have changed my rear gears added a Addco sway bar and Metco control arms. At first I thought the problem was related to tire wear, but once I changed to new rubber the problem was more pronounced. My next move is to rebuild the entire rear end and call TAF. I would like Team Ford to upgrade the Posi, axles, add a Reinhart Dynotech shaft, inspect the current gears, and remove the bearings. Hopefully this action will resolve the problem. I know these measure are costly and ballistic, but I have already replace two transmission tail shaft seals (Under warranty) and I am sick of the vibration. Oh, by the way I have 27,500 mile on my car.

My 03 has a oslating driveline vib from 78 to 82 is gone by 85 32000 miles i have it scheduledto replace both axles. I have had two months and couldnt beleave i was hearing a axle bearing. lm dealer confurmed the had bad axles iam going to have driveline looked over while in. we have a driveshaht shop that high speed balance race car driveshafts iam going to carry shaft there myself while dealer has car down.good luck.

Tranny tailshaft problems generally point directly to the driveshaft. I would change that first and check it out before I did anything else (unless you're getting some of the other stuff done under warranty).

BTW, I have a vibration too. It produces a pretty consistent roar between 130 and 140. They can't test it at those speeds on a rack, so we're going to try to clock the driveshaft (Dynoech MMX) and see if re-indexing it helps.

[maraudernkc]

Is the Vibration only at 80MPH or will it occur at the same RPM. Because I would think if its rorating mass that speed should not be the issue it would always be at that certin RPM. I have been wrong many times before. Just a thought. Good luck with the problem.

I don’t think my visit will come before April because I need to purchase some expensive parts. FordNut has a good suggestion about replacing the drive shift first. I could easily handle that upgrade with one phone call to Mr. Reinhart. The Southern Marauders are great people and Team Ford offers some of the best hands in the business. They were able to handle my tuning and transmission issues within hours. My previous track times were 14.7-8 before trany cooling mods and tuning. Now I am running 13.8-9 all day any day. Now if I could resolve this vibration issues and plug in some nitrous, life would be good.

:D

[TAF]

.... and plug in some nitrous, life would be good.

:D
Oh..."The Doctors" can help you with this^^^ condition as well... :up:

[BillyGman]

I also have a vibration issue w/my Marauder. It only occurs at certain speeds (such as 40 MPH, and from 70MPH on up. I thought it was the need for a front end alignment, but after getting that done, there's no change. my Marauder just hit the 20K mark.

Then I thought it was the wheels or tires in the front being out of balance, but I've replaced both the tires and wheels in the front, and there's still no change. I haven't had the back wheels balanced in awhile, but this vibration is also causing a visible back and forth shaking of the steering wheel, so I don't know how that can be relalated to the back wheels or tires. I'm beginning to wonder if it has something to do w/the steering dampner. :confused:

Billy, I had a similar problem with mine. It went on for over a year, through 2 different sets of tires, even did it after I had my tires shaved (trued) on the car. After a Road Force balance, followed by an on-car finish balance (strobe balance), that vibration is gone. I never would have believed it had I not experienced it myself.

Thankyou very much for mentioning that. I was wondering about that "Road Force" balance myself. I'm not at all sure exactly what that is though. I'm only somewhat familiar w/that term. So I guess the next thing for me to do is to start telephoning all the garages around to find out if any of them offer this "Road Force" type balancing. Something tells me that's going to be difficult to find. I hope I'm wrong about that though. Thanks again FordNut. ;)

Billy...when you are calling around...ask if they have a Hunter (that's the brand name) road forced balancer. It's the best in the biz...the newer the model the better.

[Bradley G]

Hey guys& gals,

I was told ,duing my quest to solve a vibration issue,that any vibe that is speed sensitive,is related to the tires.If the vibration comes on at a certain speed and dissapears ,only to reappear at a higher speed, more tham likely your tires are at fault.I complained to the dealer umpteen times(and several attempts to road force balance tires) till they relented and replaced the two front under the mfg. warranty.(BFG)Even after the new tires were installed I had the vibe.that was between 4-5K mi.It wasn't untill a month or so ago(@ 12-13 K),till the dealer (who was concidering aquiring this Hunter machine for thier dealership.)the hunter co. and the dealer used my car for thier DEMO to solve this.Hey Billy, rather than "call around" just hit a few keystrokes and you will find hunters website and they have a locator link on thier site. One warning /tip that I learned the "HARDWAY"show the service personel how your wheels look before they begin servicing your vehicle.Mine have been on and off so many times my rims are suffering from gross neglegence.Now I'm trying to get the dealer to make good on the damage.I will post the results.Good luck, I hope this helps.

-ADude,
I have the same problem on my 04 Marauder. I feel the vibration under the drivers side floorboard and it starts around 80mph and gets worse as I go faster.
Now my car only has 4100 miles on it and it has been doing it since I had it. Lots of people tell me to have the tires road force balanced. They say most likely the rear tires. I dont know if it is the gears because I have changed nothing on mine. I will also have to check the balancers on the drive shaft when I get a chance to get it on a lift. Lets stay in touch about this cause the vibration is driving me crazy too. I mean I drive I95 every day to work and my normal cruising speed is 80-90mph

If any one is interested I have found a way to find out what shops in your area have the machine that does road force balancing. Go to www.hunter.com....click on wheel balancers.....then click on Solve wheel vibration problems locate a GSP9700. When that page comes up put in your information and BAM it will tell you where to find a shop in your area that carries the GSP9700.

Happy Motoring

[JACook]

Hey guys& gals,

I was told ,duing my quest to solve a vibration issue,that any vibe that is speed sensitive,is related to the tires. Like with so many things, "it depends".

Anything that rotates can vibrate. Whether that vibration is speed-sensitive, or RPM-sensitive, depends on
what we're talking about. Basically, the transmission is the midpoint. Things on the front end of the transmission
will vibrate according to engine RPM. Those after the transmission will vibrate according to road speed.

Tire vibrations are generally much lower frequency than other vibrations you'll feel. It's more of a shake or
shimmy, than a vibration, unless you've got treadwear or separation issues. Driveline vibrations are usually more
like a low rumble or growl that will vary according to speed, and will also tend to vary according to whether
you're on the throttle or coasting. Driveline vibrations often cause things to get a bit blurry in the rear-view mirror.
Wheel bearings usually give a cyclical growl or rumble. So can a driveline, but it's a different sound. Wheel bearing
noise can often be modulated by shifting the weight of the car, like when making a turn.

Pretty much any vibration will have a resonant frequency, no matter what the cause. That is to say, it'll be
strongest at a certain RPM or road speed. Increasing or decreasing the speed will reduce or eliminate the
vibration, even though the imbalance is still there. Unfortunately, that means if you've got a driveline
vibration, and you speed up to make it go away, you're still abusing the tailshaft bushing...

[BillyGman]

For those who don't already know this, I used the link to the Hunter place that was provided and e0mailed them to ask them where's the closest place to me that they've sold the roadforce wheel balancing equipment to, and they told me about a Ford dealer who has it, and I took it there, and they did the roadforce balancing, and it's been perfect ever since.


It was very expensive, but it's the only thing that took the wheel shake out of the car. And I had the wheels balanced at two other places before who didn't have the roadforce balancing equipment, and it had not corrected the problem. So I cannot say enough good things about this raodforce balancing equpment. before I had it done, i was beginning to think that the shaking that started at 65 MPH and just got worse the faster I went, was something that i was going to have to put up with for the rest of the life of my Marauder. I'm very glad the roadforce thing worked. Thanks to everyone here for your advice on that.

[duhtroll]

Mine was roadforce balanced also, but to no avail. The vibration is still there. Judging by the above description, mine would definitely be a driveline vibration, as it starts at 80 MPH (not RPM based as I hit those rpms when shifting and no vib), is a low rumble, and gives me that slight blurred rearview mirror -- sometimes.

Raising the rear end did help, and the vibration is not very noticeable anymore. Raising the ride height also greatly improved the ride quality. It is not at max height but it is close. I would rather have it lower but it rides so much better where it is.

Mine is not wheel/tire related unless both sets are out of balance. The snows on there now are only rated to 89 so I don't go above 80 anyway during the winter. When I get my new KDW2s on this spring of course they will be balanced at install so we'll see when that is completed.

Long story short, they paid for a u-joint (front) under warranty, did nothing.

They paid for the road force balance under warranty, did nothing.

I asked them to take apart the rear end and check wear, for bearings etc. and found only normal wear. I paid $325 for this. Now I have written documentation (on my invoice prepared by the senior master tech that does the warranty work and did my gear install) that my mods are not causing the vibration, unless it is some funky thing going on with the exhaust I put on. (no way)

I still have the vib. though it is not bad now, and I have peace of mind that nothing should be falling apart as I had it checked, and it ain't my mods causing it. If it persists in the spring I will continue to find more avenues on this.

Any other brainstorming as to what this could be?

Thanks,

Big way...

Exhaust systems most certaintly cause a lot of vibration, where do you think our infamous "cabin howl" comes from? It's vibration that reaches audible resonance.

What did you do to your exhaust?

I'll tell you this right now, your vibration issue begins long before you can hear it, or, feel it. You say 80 MPH when it bugs you. I'm willing to bet it's happening much sooner, like 40-50 MPH, but not disruptive to the human condition yet. Like a cheating wife, you as the driver, will be the last to know something is wrong. Your exhaust system could easily be a responsible party, so, tell us what you did to your exhaust?

[Krytin]

You might be on to something Mac - they don't put those vibration dampers (round counter-weights) on the exhaust @ the factory for nothin'!

[Bradley G]

I have a Driveline vibe that is RPM sensitive .It can be felt through the steering wheel ,go pedal,floor, and even lightly through the shifter.It starts in every gear at the same rpm.1800-2300 then stops.It is worse in higher gears especially OD.If you decelerate it almost disapears.I have 16800 on the clock and I am running the Winter tire package with blizzaks only a few hundred miles on them.I used to have a wheel shake that was virtually elimated with new front tires and road force balance.I have Been in contact with Jerry Barnes of Trilogy Motorsports of this issue.He told me a friend, Ned Nuss Chassis specialist enginer for the Marauders.He (Jerry) said that dealers are not all well versed in finding quirky symptoms these cars may exibit.I was planning a trip to Michigan if necessary! Duhtroll If the vibe is speed sensetive it's usually tires.I had my tires road forced balanced and got little results.I got new tires and still had the vib/shake.It was'nt until 3-4 months later the dealer got around to road force balanceing the warrantied tires,to correct the issue. Did the dealer say anything about your tires possibly being out of round or defective?.

After reading all of the posts emails and experiencing the exact same thing myself - vibration at 78-82/85 mph. The low growl or rumble is very likely the drive shaft. I had two Ford mechanics where I bought the car tell me it was the axle bearings or carrier bearings going bad. If actually was the drive shaft. Balancing the drive shaft is inexpensive - $35 in Atlanta. Check your drive shaft balance before spending hundreds of dollars on other things.

Glenn

[Bradley G]

Thanks Glen,

Good info,I get much resistence from the(my) dealer trying to get this issue corrected.I get comments like "Ford is not going to pay, to chase your vibe" eventhough he( s/m) personally admitted to me at our company party(well oiled up) that he knew my car has one, If balanceing the drive shaft is inexpensive and Tailshafts have been a common issue of failure due to Driveshafts not spinning true.It would stand to reason Ford would take a pro-active approach on vehicles that exhibit this symptom, and do an balance/ adjustment rather wait till it gets towed in on a hook! With broken this and leaking that. I have documented a dozen service complaints to resolve this and I am still trying.Like was said a while ago.Marauderers' won't go away! We just keep comming back till we get it right!The Dealer(s) (mine) are more interested in the bottom line $$$$$$$$$$$$$$$$ then concentrating on what it takes to get issues resolved.With the boards help I am confident that this will get resolved.I just hope it is sooner than later:rolleyes: Thanks for listening!(reading)

I dont think it is his exhaust because Im having the same vibration and I have changed nothing on my car

[duhtroll]

In answer to above question, I have a custom DR exhaust that is stainless all the way back.

Someone suggested running it up on the lift to see if we could find it, (the vibration) but I don't know how beneficial or safe that would be.

The exhaust was installed in June. Vibration began in November. I woulda noticed something earlier if the exhaust was the culprit - most likely anyway.
