Over 40 mph, I get a rear end sway or wobble when accelerating in my '02 Nissan Pathfinder . Sway reverses when I let up on the gas. Feels like I'm losing control of the vehicle. I was told by an online mechanic that it was most likely the rear suspension links for the rear differential, the bushings are torn or broken. When broken will cause the back end of the truck to feel loose. Inspect all 4 rear links and replace which ever links you find bad.
