I'm not sure if I ever posted this over here, but I know I searched for a solution at one point. Since it was new, my 2005 S60R exhibited a strange vibration during medium to sharp, low-speed right turns. It almost felt as though it the car was driving over rumble strips. You could also feel it through the steering wheel.<p>The dealership tried several times to fix the problem during the past year (now have about 8k miles on it), by shimming the front wheels, tire balancing, alignments, etc. Finally, I got fed up and escalated the problem to their Senior tech when the vibration started happening more frequently, on left and right turns!<p>The tech ended up replacing the Steering Box (Part# 36000130-9), the Steering Shaft (Part# 30741959-7) and the, not sure what this means, Power Steering Rack (30741424-3 x 2). <p>Now, even though I have a squeeking sound in the steering wheel (going in on Monday) as a result of the repair, the vibration is gone.<p>I hope that information may help someone in the future.
