I recently had to have my 960 looked over real good at a reputable, experienced frame shop. It was pulling to the right after several alignments and alignment checks, two new tires ($160.00), etc. There are some things, front and back, that cannot be conventionally aligned but have to be measured, replaced and REMEASURED, which is usually the step some shops miss, or the part has to be sophisticatedly bent. Some do not bother to seriously look at the back because the computer tells them that nothing can be done back there. This was part of the problem with mine, it was several degrees out because of a bent camber from a poor lift placement. The car was lifted for an oil change, or something, by placing the vertical part of the lift right onto the camber! Watch this. Make sure the frame shop has experience with the 960! Volvo dealer frame shops are not always the best, I have found. In fact, mine was so honest about it that they referred me to a frame shop that sees a lot of wrecked vehicles. Hope this helps.
