I have a lot of clunking going on when initially taking off from a rest and when decelerating at low speed. I have found the front drive shaft on my 88 YJ has about a quarter turn of play in drive shaft and it sounds eerily familiar to the noise I hear under power when I turn it by hand at the end of play. I have an automatic locker in the rear and this has been with the transfer case disengaged. I would imagine a certain amount of lash but this seems excessive. Any help would be appreciated.
