My rear is lumpsided

[adrian36]

Ok, enough with the comments :pill: I have noticed that the driver's side rear is about .5 of an inch lower than the passenger side rear. I have moved the car to even pavement, had my neighbor 250+ pounds to sit in the rear and the car sinks but the air bags kick in and the susp. rises. I had him sit on the pass. side rear and the susp rises but the driver side is still .5 inch lower.
The rear driver side is exactly .5 inch lower than passenger side rear. The front is completely even 29 3/8 and 28 7/8= .5 inch lower.

Please any ideas or suggestions will be appreciated. Thanks

Is it normal for the car rear susp to be off by .5 inch or should I take it in for warranty??? Any help would be appreciated. Thanks :flag:

Ardian, how are you taking these measurements ?????/

Your car hasn't been in an accident has it???

I am measuring from the ground up, center of rim to the fender. The right way. help

No accident, clean only 9800 miles

Are you refering to the rear bumper cover? There have been threads refering to this problem here. If it's the actual frame height that's off, I would take it in. I'd take it in for the bumper cover also. Either way, you spent good money for a new car and it should be right, and even.

[adrian36]

I stand in front of the rear tire facing the rim god's head. It is sagging .5 inch on driver side rear. Pass. side ok

[Paul T. Casey]

Definite trip to the dealer is what you should plan. My buddy had one with both sides of fenders down over wheels (fender lip covered top of tire). It just plain didn't look right, especially next to mine. I told him, he agreed that it was different, but he liked the look. There is a sensor for the air suspension, I don't know if it can be tilted, but you can adjust overall ride height with it. When you put the smaller front springs in, it's how you restore the original rake to the car.

[BillyGman]

It sounds to me that what Paul is talking about is much more serious. I wouldn't go to the dealer just yet if I were you.Not to sound rediculous, but if you're measuring it that way(from the wheel to the fender lip), then have you also checked the PSI in both back tires before you do that w/a tire pressure gauge that's accurate as well as repeatable? I wouldn't measure it that way. I use a flexible tape measure and take the measurement from the pavement to the fender lip. That way, you take the tire inflation differences out of the equation. And by doing it that way, you just might find that there's only a 1/4 inch difference between the left and right sides. Which is nothing. Personally, I wouldn't even worry about a 1/2 inch difference either. That isn't even something you can see. My Vette was the same way. The only reason I measured it was because I just replaced the rear spring.


But you might want to make sure that one of your rear shock absorbers aren't broken in half or bent right in the middle. I say this because of the fact that when my Marauder had merely 4,000 miles on the clock, I noticed that the driver's side rear shock was broken in half, and the passenger side rear shock was bent right at the same place. And I didn't even know it. The only reason I noticed it was because I went to remove the snow tires that I had on. I assumed the shocks were broken because of the boneheads at one of the dyno places that I went to, since they put the tiedown straps around the shocks (I learned about this at a later date) but now you have me wondering if it was due to faulty shocks. Some people claim that shock absorbers cannot effect the ride height at all, but I know for a fact that this theory is NOT true. The shocks won't effect ride height as much as the springs will, but they WILL effect it to a lesser degree. Anyway, I suggest that you check the two things I mentioned, and get back to us to let us know what you've found. I'm routing for ya here. :banana:

I measured from the pavement up the center of the rim to the fender. I did check the psi in tirew with a digital tire press. guage. Tire press. even. I cant see why it would be off by .5 inch. It is obvious to the naked eye. I will call the dealer to see when I can take it in.

[FordNut]

I believe there are specs for measurements from frame to ground, probably in alignment or frame straightening specs. If the measurements from frame to ground are ok that should rule out a suspension issue, then it would most likely be the body mounting bolts/bushings. I have heard of these being loose on some cars, usually the complaint is a clunking noise in the rear.

[BillyGman]

I don't know what made you even measure that in the first place, but I bet that if you went in a parking lot and started taking those same measurements from left to right on peoples' cars, that you would find that same 1/4 to 1/2" difference on more than half of the cars on the street that have more than 5,000 miles on them. It would be another story if the difference was 1.5" or more. I still think it's no big deal unless one of your rear shocks are broken, but it's your car dude. If someone is driving behind your car they would never notice an uneven ride height. That's what I meant. You notice it, since you've measured it, and you know it's there. But I think you're worrying about nothing. BTW, I hope you checked the shocks like I suggested.

Will check and keep all of you posted. Thanks again. Plan to go to dealer on Thurs 9-16

This past weekend at the track, I noticed a differnce in my rear ride hight as well. I haven't mesured yet, but it's no more then 1/2 inch. I'
m not to worried about it at this point.

[SergntMac]

My MM is likewise off the mark. My left front is higher than the right front, and in the rear, the right side is lower than the left. I thought about it, and I think is't just the body/frame adjusting to the torque under hard power. I can't say it's noticable, I didn't detect it. I only noticed while writing down my specs. I don't think it's a sign of any problems, IMHO.

[CRUZTAKER]

Mine is a rear side to side difference as well....but it ussually happens when I am on a piece of pavement that isn't quite level. If the car is parked upon such pavement, one or more wheels will tend to appear up into the wheel well more than that of it's pair.

Sometimes it's hard to find a truley level section of pavement as most parking lots and roadways have a natural pitch to move water when it rains.

A measurement taken while on a lift is gonna be the closest to level.

I have seen how the NASCAR folks do it, and they must spend tens of thousands of dollars for a special floor unit that sits upon their garage floors to keep the car perfectly level to get precise suspension measurements to meet NASCAR track heigth rules.

[Zack]

I had the same problem once before, never quite figured out what caused it.
I took the entire air suspension apart, reinstalled it and still the same crap.
Then I readjusted the rear sway bar, but it still was uneven. A few days later, it was sitting perfectly level and I dont know why.
That was a year ago and it is still level. My front suspension is off, passenger side is higher than the drivers side, I just stopped worrying about it.

[TheDealer]

It's not a hand built car. There will be slight differences. Check the rear. It's always off center. One wheel will be closer to the inside of the 1/4 panel that the other. The same with the front fenders. The chassis is built first and square. The body is them put on. If you start off with a 1/64 difference in the front it will be 3/8 buy the time it get to the back. If you start adjusting the suspension the car won't track straight. Just my .02. RAY

What Fordnut said. Your begining measurement should be at the frame corners down to the floor. Again be sure you are on a level surface. Measure the same point on each frame corner. These measurements should be close to equal on front and rear. The front to rear will likely be different and that's fine. If these measurements check out, then you have body panels that need adjustment. I don't think for a half inch or less I would adjust fenders, etc. We used this method checking race car suspension and it tells you a lot before you get on the scales.

[Marauder]

A few members here have had that same problem. Mine is also about 0.25 - 0.5 lower on one side depending on where I'm parked. Even after I lowered the car, the car still have the same issue. I'm not too concerned about my car unless one side is seriously sagging.

[FastMerc]

My car is doing the same thing,been to the dealer they called Ford they wont touch it,they said it was with in spec.Nothing I could do.

The dealer said that as long as it is only 1/2 inch and within spec. I still think it is not normal but it is a F-O-R-D.
