We have brought the car in the dealer and on the stand they've said front left tire has slight deviation when rolling. We have checked the tire (all 4 are new) and the rim and they are balanced and the rim is not bent. Further they will diagnose when we take off the rotors where that inbalanced rolling is coming from. We did measured the rotors and they are not wrapped, they were replaced 15000 km ago with set of OEM.

p.s Interesting is that the steering wheel shaking or shimmy is only shown at 80-100 km/h at specific cruising speed. On highway speeds 140+ no shaking at all. When braking though there is wheel shaking. Under 80 km/h no shaking when braking.

If you have an out-of-round wheel that's the pre suspect. I had belt delamination in a high performance tire once that presented like a wheel weight fell off but just at certain speeds.

Swap that tire opposite corner if you don't have stagger set (don't worry if they are rolling backwards for the test just avoid driving through water fast for risk of hydroplaning).

If you can't swap opposet tire install the spare one corner at a time. The spare loads the suspension differently to a significant degree that bends things inwards at the contact patch vs outwards and is the best way to determine which corner is causing the shimmy/shakes/noise.

@andrewynn thanks for sharing....in my case had i am pretty sure something must be bent on passenger front end causing steering shake and outer tire wear only that tire up front...gonna go for alignment n actually hang around and see and ask for a printout of camber toe offset etc

No reputable shop won't give you a printout of before/after.

Camber is not really adjustable unless adding camber bolts. Factory pins it and the pin can be removed but you get like 0.5° adjustment. If something is bent to where camber out of whack get some camber bolts.

Oh: common problem that will make shake: zero toe. The tires need to be attempting to drive towards each other to keep tension so they won't wobble like a bad shopping cart.

Often the sometimes wobble hapoens when a barely inward toe becomes zero or outward under the right load/road conditions.

Ok great thanks will bear it in mind, but how does one know if you dont get a before or after if anything has been adjusted?

We've had the car recently for alignment and it's all perfect. Everything is in green. Tires are perfectly balanced and new. The wooble and shimmy wheel still persist, last plausibility is a play in steering rack wich the SA told me it could be caused by that.
