Handling missbehaving after impact on rear right wheel.
Hello, I've got an issue with my 156. It's an 98' 2.0 for whatever it matters.
I had a slide during the winter which made the rightside backwheel hit the curb rather hard. After this the car have had a severe handling problem.
The problem is very inconsistent, so it doesn't feel like it has anything to do with the tires or rims or anything revolving. (Not to mention I've changed the wheels around with no change).
What happens is that it can almost at random slide out the back in either direction, in higher speeds or on very slippery surface this can be problematic as it's almost enough to put the car completely out of control.
I was a bit baffled with what it could be, also noting that on dry non-slippery surfaces, it's barely noticeable at all, to the point where I can't say for sure if the little I do feel is imagined or not. Things went dry and the winter caved, so I've been running on my winter tires on the dry as they needed to be replaced next winter anyway. And what I see now is that on both tires, there is massive amounts of wear on the inner side. This is to the point where the outer tracks have about 4mm depth, while it's completely worn down on the other side, even with a small line of metal.
The tires were completely even when I put them on, and never had this kind of uneven wear before. So to me it seems that this was caused by the impact.
So there we arrive at my actual question: what could cause both wheels on the rear to be affected in this way, by a single impact on one side?
What really strikes me as odd, is how it happened on both wheels, if only one, I'd assume something got bent and got the wheel out of position..
I've looked underneath, nothing really bent or visibly damaged, stabilizer rod (if that's the english term) seems a bit poor, will replace that but could it make something like this happen?
