Rear suspension camber/ bent arms?
 

I was driving about 90 on the high way at night when suddenly from out of no where the car jolted, from the rear right wheel. There was nothing in the road, maybe it was a pot hole. But anyway, I had to get home and kept driving about 200 more miles. Well, the rear right tire is completely worn to the threads now and the tires are only 2 months old. The rear wheel is sitting with about 5 degrees of camber, it is severly tilted. I jacked up the car and took about an hour to check out everything. The subframe is definitely not bent. The arms and camber link look the same from left to right and the left rear wheel sits perfect. After very careful inspection nothing looks to be bent, but the camber is way screwed up and I cannot drive back to colorado with out new tires and the rear right will completely wear out again, just can't afford it... I need to get this problem fixed, does anyone have any suggestion about what might be wrong. I mean the trailing arm is identical to the left side, the camber link is perfectly straight, the subframe wasn't disturbed. What else could it be? Could the upright have gotten bent or something? Aside from replacing the whole right rear side of the suspension I don't know what else to do. What would allow the rear tire to sit so slanted if all the suspenion arms aren't bent?

I'm baffled, any insight?

I am no expert, but could be the bushings or wheel berrings.

Sounds like the same problem i have, havent fixed it yet heres some help. So it feels like the rear end is swaying a bit at highway speeds ? thats what mine would do.

Actually handling feels fine, though Ive been driving around a little slower than usuall, but the tire wear is unnaffordable.

check your springs/shocks assembly

most IRS RWD vehicles have camber eccentric plates to adjust the rear camber, i would get under there and look for an eccentric shaped plate or adjustment bolt and see if it looks like it has come loose and allowed the adjustment to spin.


5 degrees is huge for a camber adjustment, i don't think it is quite that severe but if it is i would think something has to be bent, most camber adjustments will not go that far by adjustment but i would check to be sure the bolt hasn't just come loose allowing the camber to slam to the furthest down setting where gravity is holding it.


if you don't see anything wrong with the adjustment bolt then i would check to be sure all your rear control arm bushings are still in one piece and not squished.

I got the car up on a lift and everything looks fine, all bolts are tight and everything is solid and we determined that the whole arm assembly must be bent just slightly overall. Camber is actually at 1.5 degrees, but it looks pretty tilted so I exagerrated with the 5 degrees. I decided to buy adjustable camber links from rotorsportracing since they will most likely allow me to fix the tire wear problem easily and right away and then adjust for better performance in the future. After some more $ comes my way I'll just replace the whole rear arm assembly to make sure everything is symmetric. Super gay though that Discount Tire will not give me replacement tires, I say it was a road hazard damage since everything was fine before, plus the fact that I buy tires like once a year and drop some good dough, I should take the tire and throw it through the window like in their commercials...
