I have a 1991 W126 chassis with new Michelin MXV 205/65/R15 tires that are shaking the steering wheel starting at 53 MPH. Switching rear tires to front produces same result. Tires have been Road Force balanced by tire shop and they insist tires are perfectly balanced.

My regular indie MB shop (Jarek's MB Shop of Knoxville, TN who I trust explicity) insists there is no mechanical reason for the shaking, "ball joints, tie rod ends and steering shock etc. are fine".

I'm at a stand off with the tire shop and mechanic.

Could really use some advice on this.

Thank you.


10/28/2010 UPDATE: Tires were rebalanced again using Road Force method "with special care" according to the tire shop manager. My shaking is cured now. My regular MB mechanic confirms that W126 cars need special care when balancing tires.
