1991 Nissan 300ZX

1991 Nissan 300ZX 6 cyl 170000 miles

Hey Ive got a 300 that runs pretty good, I need to do a few minor replacements but to get to the point. When I am going around a right corner or if I make a right hand turn with a some power behind it (not enough to let the tail end come out) the entire car shakes and almost feels like it bouncing! This does not happen at all when going to the left! It almost feels like the right wheel isnt spinning like its supposed to. Ive had some ppl check it out and no one can "recreate the vibration on the lift" which is whatever but Im afraid I may have a problem with my limited slip but I know nothing about that or how to get into that and I dont want to go paying someone money just to take it apart to tell me thats not whats causeing the problem! Any help will be appreciated please!
