Clunking=U-joints...Yep...Think Again!! :(
Well I had some clunking noises in the rear...after researching and checking around I was pretty sure it was my u-joints. So I figured what the heck and threw in new spicers all around (driveshaft/both halfshafts). So today I take it for the first cruise...going great....start out...Clunk! Its from the rear right side...I just about pulled over and walked home...luh...
Rambling on . . ..
Anyway, The QUESTION I was going to ask is....
If it is coming from the passenger rear what else could it be...Wheel bearing...gear slop???
BTW...I drained and filled diff with new 80w90 gear oil and limited slip additive (4oz). So whats going on???
Thanks

Hmm...spindle eh...
If some grease took care of it I sure wouldn't mind...I am gonna take it to a shop tomorrow and let them take it on a test drive...with me accompanying of course...see what they think.
Here goes nothing. . .

This topic has been beat to death lately. If you search on the word clunk in the archives you will find a number of threads discussing the potential problems.
When I was getting the same clunking noise it turned out to be my C-Beam plate (Torque Arm) bolts had worked themselves loose. A number of others on here experienced the same problem. You may want to take a look at that as well.
Good luck,
Mike

Watch your shifter when you press the gas. If it moves up a significant amount when you put it under load then you'll need to tighten the torque arm bolts. It can make some very nice clunking noises.

...It won't be the case for you I'm sad to say, but maybe noteworthy when this thread ends up in the CLUNKing database archives;
I washed my car yesterday then drove forward to garage it.
Next day as I reversed it clunked as it began to move; Rear brake pads stuck to discs, prob kindof glued there by water...
Sorry this isn't where your probs end. Good luck. :banghead:

I agree Scorp but there are is a lot of info in the archives on this problem. It's a tough one to figure out that's for sure. I hope he gets to the bottom of it without it eating a hole in his wallet. I consider myself lucky.

Its likely the spindles, pull off the hubs, wire brush the surface rust off the splined spindle shafts, and hub insides, slather antiseize grease all over the splined shaft and it should eliminate your noise.
As it did in my case (clunk/click when you'd go to accelerate). Easy fix, toughest part is unbolting the hub from the inside of the rear suspension. Clean off your ABS sensors (bolted to the rear suspension) as well while you are at it.
Imagine how bad the dealer would rip you off if you took it there and told them about the clunk/click.....

I should also mention if its the spindle problem....Theres nothing wrong with the spindle, just the surface rust causes some kind of noise for some reason.
And yes, I am describing the same thing scorp mentioned.

Wow...I had been reading alot of those clunk threads...even commented in a couple...so yes...it has been very much beat to death.
I think I will check the spindle then...I mean I am pretty familiar with the rear suspension now... :crazy:
BTW I need to thank Scorp for his how-to on u-joints....it saved me $600+ to do it myself!!!
How do I check to see if it is a brake pad hanging up though?

*UPDATE*
Just took her around the block...I didn't see any movement in the shifter and also I should tell you the clunk only comes when leaving from a stop.
I have the C-beam plates for ZFdoc so maybe that will clear it up...but I am pretty positive that the c-beam bolts are still torqued down real tight.
Hmm...any tips on getting to the spindles is appreciated.
And how to check those pads....???
TIA

The spindles are nearly the same job as pulling the halfshafts. You need to get the knuckle loose like you did before so that you can unbolt the halfshaft from the outer spindle and then push the knuckle out and the halfshaft up out of the way.
The only other difference is that you need to remove the cotter pin and retainer from the end of the spindle and then remove the 36mm nut from the spindle. Once you've done that they should slide right out. If they don't slide right out grab a piece of wood and put it on the end of the spindle and whack the wood with a hammer. That should break it free and out of the wheel bearing assembly. I would suggest removing the 36mm nut before you unbolt the halfshaft from the spindle.
