Rear Driveshaft play

I have a clunk from the rear occasionally and while re-torquing everything I noticed my stock rear drive shaft has play in it when I when I try and rotate it by hand. Is this normal backlash?

It is normal for the driveshaft to have some rotational 'play' in it. This is due to a combination of Ring & pinion gear backlash, spider gear backlash, and axle spline clearance.

If you want to get away from that occasional clunk, invest in a better driveshaft. Or you can remove it and grease the splines (slip-shaft), sometimes that helps.

Compare a stocker with a JE Reel unit...

Spent some time under the jeep today. Looks like the clunk was the spring retainer clips I installed. I used Metalcloak rear spring retainers and I think it was making the upper part of the spring spring shift a little since the bottom was pinned in place with the retainers. I also have synergy wedges to straighten the springs. Took the retainers off and clunk is gone.

Or the spring was binding a little due to the design. I also have synergy wedges to straighten the springs. Took the retainers off and clunk is gone.

Nice investigative work, I don't think anyone would've ever guessed that.
Lol, believe it or not, I Googled the problem and some guy in a Subaru forum said it was his rear springs. Got me thinking about the parts I just installed and whammo, problem solved.
