V70R Suspension Issue
 

Hello all, has anyone experienced a suspension issue on this model? I have a 2006, 44K miles, when I hit a pothole, speed bump, manhole, etc, the car feels like it slides or skips, especially the rear end. If anyone has experienced this problem I would very much like to hear your feedback. I have made one trip to the auto shop with the problem, but no resolution.
One note, the front axel was replaced recently, and problem appeared shortly thereafter.
I have checked the tire pressure and keep them inflated to spec.
Thank you.
