Rear end knocking under Acceleration and upon Deceleration

TripleC · 02-18-2010, 03:21 PM

I think My rear end is starting to show signs of ware. It just started clunking a couple days ago. I have been driving it hard lately so i am under the impression i could have jacked the crush sleeve. I went under the car yesterday and the drive shaft had about a 1/5 turn rotation of play and i could feel it pop through the drive shaft and here the noise resinate through my Traction arms for the noticable poping sound. well i tightend my traction arm that was a little loose to see if this would help. It did not help at all!

Do i just need to replace fluids?
do you think i jacked the Crush Sleeve??(what i think)
Or have i done more damage then i thought?
(The problem is in the diff and not bushings or subframe)
It is still driveable and there is no sound until i shift then i here it. what do you guys think.
PS it is easy to here at slow speeds but the car is loud and i cant seem to here it as much from 30-50..
