Driveline Play/slop problem

[mzollo]

To start off, the car is an m20/g260 powered early model, rear subframe completely rebuilt with all new bushings, Poly Ta bushings, and Condor solid Diff and Main Sub bushings.

The Problem.. the car has a very noticeable front to back slop in gear, any gear does not matter. lift off, feel it, get on throttle feel it. tap the throttle a few times and you can send the car bucking back and forth. its extremely annoying.

I also managed to get a small video with the car in the air, as well as one isolating the sound on a hill. I would like to think its the either the driveshaft or backlash/play in the Diff itself. what are some opinions?

Check the rear ujoint on the driveshaft they tend to go bad and buckle on and off acceleration.

rear ujoint would be my guess as well

My car has the same slop in the rear wheels... I have all new poly bushings in the rear suspension and a new drive shaft. I'm thinking its something with the tranny but I don't really wanna dig into it lol
