Driveline play opinions

[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?

Kind of sounds like my car. I still don't know what it is even though I replaced every bushing

jack up the rear end on the diff, place jack stands. leave car in gear

crawl under car and try to rotate driveshaft by hand near the differential input shaft. I am willing to bet the rear u-joint that bolts to the diff is toast. hit up blunttech for a good price on a new driveshaft with replaceable style ujoints
