Hi all I had the tracking done last October, wheels balanced etc. On both sides the inner 5% is scrubbed & has gone down to the steel bands! The remaining 95% is fine. It is not the 1st time this has happened & I also had it on my E300 too. Also get n/s wheel wobble which presumably is when the wheel gets further out of balance & the car pulls slightly to the left whereby you correct it with the steering wheel. I took it to a non MB garage and the mechanic said there was play in both front wheel bearings & that was the cause. Is he right? As always any help much appreciated.
