So i have this vibration on the passenger side. it onlyy happens when i move the steering wheel left..
-Wheel bearing? dealer replaced it...still vibration...
-I have 20' falken 452's 285/255 tires; too aggressive? no dealer put stock rims and tires on to test drive it..still vibration..

what else could it be? they have been working on it for 1 day and still no diagnosis! Any ideas? tie rod, axle, steering rack?

 

dealer must be really dumb if they can't find the problem.. take it to different dealer shop.. it's useless asking us right now since your car already at the shop...
