since installing new bridgestones, I'm on my 3rd wheel alignment. first alignment, steering wheel moved about 5 deg to left, 2nd align; went to right about 5 deg. now its back to the left. had tires rotated, balanced, twice. Volvo dealer sezs its radial tracking, swapped front tires, corrected the problem for about 200 miles. Discount Tire sezs its the car and not the tires. I say its the tires.
Very frustrated. COMMENTS PLEASE

 

After 3 attempts of realignment and with the benefits lasting a mere 200 miles the problem has to be a mechanical issue. Steering / suspension fault of some kind.
Do you regularly have need to mount any curbing or maybe cross a cattle stop or the like in the course of your regular and routine travels?

 

Placed 4 new Yokohama tires on my XC90, had them balanced and all 4 wheels aligned. Took a drive up the Grapevine in CA and had trouble controlling the car in the lane. Felt like right front tire was pigeon toed, I was fighting the steering and changing lanes it felt like it would roll over. DTSC dash light went on and then off. All in the rain! Did the same for the rest of the trip. Rotated front to rear thinking it might be radial slippage, but still the same feeling and a constant pull to the right. Going to the left around corners on the highway it would give the feeling of being hit by a wake in the rear end. Any suggestions?
