The Nissan Path

hallo everybody
i have a problem. my 2002 starts shaking / wabeling in the rear when i drive over 55 mph, it stops as soon as i go a little slower or faster.
i changed the shocks already and there are new tires on it.
does it maybe have anything to do with the sway bars and bushings?
thank you

anyboda a idea??

My 05 had a very similar type of shake. Turns out I needed U Joints. Get it checked out. This might just be your solution.
