I recently had my car fixed after doing a 180 into a curb at about 100 miles an hour. They told me my rear crossmember was bent, but like you i couldn't tell by looking at it. I would reccomend having that checked again to make sure it's bent before you replace it. Also check for any damage to the rear knuckles. Those two things, along with a 4 wheel alignment should solve your problem.

Hey BoostedRex,

that's some interesting info! Did you have to remove the gas tank to access the cross-member? How much did the cross-member and knuckle-joint replacement cost?
Did you have problems with vibrations at any point? Did you get them fixed?

Thanks!

Dave.

The gas tank does not have to be removed to replace the crossmember, but it makes it easier. The rear axle does have to be removed. I did the repair myself, so i don't know how much it would cost.

Nice! That must have been quite the work-out. Trying to hold a differential in place while driving bolts isn't the easiest job. Did you have air tools and a hoist? Was it difficult to get everything properly re-aligned (i.e. driveshaft to differential, differential to sub-frame)? Did you need any specialty tools to replace the cross-member?

When you say "rear knuckles", you mean only the ball-joint assemby? At 100 MPH, I expected your spindle to bend for sure! Anyway, I'm gonna see if there are any shops that can re-build the ball-joint assembly . . . specifically the outer shaft attached to the wheel. If they're OK with a ball-joint shaft re-build, then I'll consider mounting a new spindle (housing) at the same time. I presume I'll need to buy a new wheel bearing again for a new spindle?

I'm still a little hesitant to invest all that money to replace the cross-member. I know the shop will totally screw me for labor and you never know what else they can screw up during the re-assembly.

Dave.
