need help. uneven tire wear after replacing lower control arm

Replaced one of the lower control arm in local dealership less than 2 months ago.
Drove 3k miles. I just found that both front tires have bad outside wear.
I felt the returnability is weaker than before, and the steering wheel won't return if I turn all the way to one side, e.g., parking L spots.
I went to the dealership again today. They said that the alignment was fine. The advisor said he needs to "do some research".
Does anyone have similar problem? Any suggestion?

I had to take mine back after the new lower control arms "settled". The "toe" was off and would pull to the right. (Same side that it was pulling to before). You may need to push hard for it but if you can prove you had rotated the tires, maintained propper pressure etc... Then in my opinion the tires should be replaced.

Sounds like final tightening was done in the air so when it hit the ground the outer edge is getting more contact than the inner edge. Done right, you get all bolts to 90% tight, move it to an alignment rack and do the final tightening then with the vehicle 'settled' in normal driving position.

I'd say your dealer **** up. New control arms should not affect the feel of the car at all.

I disagree. Mine was pulling before the repair.

I did my service in (another) dealership right before that. I have a copy of the inspection record showing they did tire rotation and also measured the depth of tire threads. It seems that they pulled the record from GM.
I went back to this one simply because I bought my trax there and the time better fits into my schedule. But it seems to be a big mistake.

could be.
In that case, should the problem only appear on the side the replaced? (they only replaced the passenger side). But both front tires were worn in the same way.

I don't know or understand why they would only do one side, especially under a recall situation. If one side is showing failure, due to design or assembly, it not only makes sense but is more cost effective long term to replace both. The possible liability alone for a dealership to do that boggles my mind, especially if you bought it from them.

As for the tire wear, if it's not related to them screwing around with front end parts; then they just swapped your wheels and tires with someone else in the shop.
