One Wheel Wonder?!?!?!

[Egon Spengler]

My car won't kick out sideways anymore when I want to fish tail around corners!!! What did I break?:mad2:

[Eric-Blk2004]

Yer mojo...

[arejayesss]

Well, at this point with your given mods, you do not have enough torque and or power to break BOTH tires loose, so most likely one tire is breaking loose and the other is being kept 'on track'

[Egon Spengler]

It has always done it for me before and one day I tried it and nothing... I should say that it is on wet pavement that I usually do this... so I do break them both loose. It does do this on dry pavement!

Even bone stock mine always caught posi on a hole shot

[ROB502]

Posi clutches are burned up....:burnout:

[Egon Spengler]

I did that burnout the other day and it put down that posi strip, but when ever I try to kick it out on a right hand corner... just the right wheel spins... when I kick it out on a left hand corner... they will both spin... I know I messed up something!!

[sd8683]

Isn't that the limited slip kicking in

Probably....replace them with

I have marked the parking lot at work twice. once a straight shot leaving two stripes and the other leaving a parking space turning right and left a single right tire stripe. Out on the road I have broken both tires loose on a left turn corner but I can not remember ever doing it on a right turn. I doubt anything is wrong, its just automotive science.
I seem to remember a charger or super bee having an extra leaf spring on one side of the rear end for this very purpose.

^^^ Speaking of right hand turns, I know my car has always laid rubber on the right tire on a right turn. Both tires will lay rubber on a left turn.....weird.

Great, Lately I have taken the car out and left 2 very solid strips of rubber down. At a recent breakfast meet my right tire went up in a blaze of glory but the left one didnt. This prompted me to buy a carbon clutch kit when after hearing this its very possible that I didnt need it!!!

[BADMERC]

Your clutches are TOAST! You had better look now. It will only get worse.

[ctrlraven]

Yeah I noticed mine are going when I was at the track this past Sunday and the left wheel slowed and then stopped. Big warning sign was the amount of rubber on the bumper lol. Passenger said hand a handful and driver's side was a fingerful.

I'll be getting all that taken care of when I do my 4.10s next month or sooner.

I suppose when the car leans over to the left when making a right-hand turn, the weight is distributed mainly to the left-rear, allowing the right rear to spin freely. I guess on ford's limited slips the right rear is always a little stronger even on our cars. Which would make sense that when making a left turn both break loose, because the weight goes over to the right rear, (free-ing up the left) but since the right one is stronger it still spins.

It's not 'stronger', but IS the traction wheel when the dif is slipping. MM will always fishtail left on a straight burnout. Right breaks before left. Left is still pulling forward, pulling car left. left breaks, both spin. Input torque pushes the dif clutches together.

Tj, do you know the history of the car before you bought it?

[Stranger in the Black Sedan]

The stock posi's are notoriously non aggressive and wear out fast. My stock clutches must be set up tighter than everyone else's because they grab both wheels even on moderate application of power when cornering. I had to add 2 bottles of additive to Redline fluid just to calm down the over aggressive limited slip action (and chatter). Sounds like your clutches are on the way out.

Bought it from Lamoreaux Ford in E. Brookfield have a car fax but will have to look at it again. It was owned by an older gentleman who was a fire department chaplain which was cool seeing as how I am a fireman myself. I should get an oasis and car fax done again... never had an oasis done... what is that?

[justbob]

Just had my clutch pack replaced under ext. warranty, i had to agree to pay if found to have been abused but it was found to be a ford thing (idiots)Anyways was told that it is in fact a problem child and has been replaced with a different part number and is supposed to be alot stronger(we'll see about all that) but ford did say that it strongly recomends soaking the new ones in friction modifier for 24 hrs prior. My car was still leaving two marks but was just starting to chatter. Hope this helps. Bob.

[Stranger in the Black Sedan]

Maraudingforlife, that's interesting that yours chattered as it began to fail -- mine locks aggressively but I had to add 2 whole bottles of Ford lube (4 oz each) to get the chatter when cornering at very slow speeds for it to stop. I'll keep my fingers crossed

[Marauderjack]

Mine has 167K miles on the OEM clutch pack and still does the "Two Stripe" quite well......NEVER spun only one wheel even around corners, but I don't do burnouts nor really abuse it!!??:shake:

Just wondering how involved it is to replace the clutches??:confused:

I will probably do the axles soon just to be safe!!:cool:

Marauderjack:burnout::burnout:

[justbob]

mine was at take off (straight) at about mid throttle, something in the rear of car was sliping plus a slight vibration thought it was maybe a u joint but it was the discs. I just caught it early and i only noticed because i usually drive my escort most of the time and every time i drove the mm i could notice something wasn't right and that something was about to fail and then it would be harder to claim on a warranty.

[justbob]

mine has 46,000 and only raced at the strip once. Out of fords mouth it was a weak design and they have fixed many.

Something doesn't look right in this picture. Your pretty much stock MM left these tire marks? That's got to be nearly 100ft! Even while doing this when wet, I don't think it would leave marks like these. When my MM was stock, I was lucky if I got 5ft from dead punch. Now supercharged, leaving marks like these from a dead punch is a walk in the park.
As for your one wheel wonder, trying to break the rear end loose on a right hand turn puts tremendous stress on the posi clutch plates. If the left tire has more traction than your posi clutch, then your clutch will slip instead giving you one wheel spin. When attempting this on a left hand turn, it puts a different dynamics on the rear axle. Imagine looking at the car from the rear, when going forward the driveshaft spins counter-clockwise and thus it is trying to spin the axle housing in away that it's slightly lifting the right rear tire therefore making it have slightly less traction. When making a left turn, the weight shifts slightly to the right wheel and most of the time this will equalize traction and with the help of the posi clutches, both tires will spin on a left turn attempt.
This is why on an open end rear with both tires being equal, on a straight line launch, the right tire always spin while the left just goes for a ride due to the right tire being lifted slightly from the driveshaft spinning counter-clockwise. If you were to put the car in reverse and punch it, the opposite will happen where the left tire will break loose and the right goes for a ride.
If you like to kick the rear end out on a regular basis from a right or left turn, I recommend replacing your stock posi with Torsen T2R unit. These unit do not have clutches to wear out and they have much higher torque bias than factory Trac-Lok. They're the next best thing to have to lockers.

He probably did a brake stand there


tjmorin82: I think its the clutches, and an oasis report is a report of all the service your car has gotten at ford dealers. They run your VIN # and pull it up. Pm RoylPita with your vin and he will run it for you, and if you ask he can tell you your marauders sequence number to ;)

I put the car in first and did a brake stand for about 5 seconds and let off the brake with my foot to the floor and left it pinned and in first till it stopped spinning them... The tires are fairly low on tread and I have a K&N Intake... Thats it... Stock other than that... I thought it was pretty impressive!!!!

[Egon Spengler]

THe road was dry too!!! I too the pic right after doing it!!!

Do you still have the kit or did you install it?

[Blackened300a]

Do you still have the kit or did you install it?

The box is sitting in the office waiting to be installed. I figure I may as well go ahead and do it before I really have to.

[Krytin]

That would be my choise if I were you - but if you should change your mind (you really shouldn't) I know I would use it on mine.

[Blackened300a]

Yesterday I had a brake flush at my friends shop and then I was pressured (:rolleyes:) into a burnout when I was leaving. I hit the gas and two 20' stripes were left in front of their driveway. I dont need it but I plan to throw it in since I already bought it.

[Krytin]

Yeah right!!!
I'm sure you were "pressured" - must have really twisted your arm!!!
Glad to hear it still lays down a nice set of stripes!
