Hi, my 2001 V70 (non-turbo) gets quite bad vibrations at 45-65 miles, especially when accelerating peaking at about 55 miles. If loaded, vibrations start a bit earlier. When the car goes faster, these vibrations calm down. Even when completely lifted from the ground, and the wheels taken off, the vibration is still present. They tried propping up the engine a bit assuming that the mounts are bad but to no avail. It looks like shafts are a bit bent and wheel hubs are far from fully perfect (140,000 miles on the car) but the vibrations are too strong to be caused just by these factors. CV joints seem OK in a sense that they are firm, make no noises and seem to be lubed. What else do you think it can be? Thank you!

I have the same issue with an 01 V70 2.4t with 85k FWD. Same speed and same vibrations. The steering wheel all the way down to the floorboard. Have you come to any conclusion? I find that it only happens within the first acceleration. Then it's gone, but if I drive a while it usually doesnt incur the vibrations at speed. I could also see how my driving patterns could play into that.
