I've replaced my camber link w/the on car ajustable one, still have the clunk. Talking about it pisses me off.....now I must to know what the hell it is.
any other ideas?....... [/quote]
though you have replaced the camber link, are you sure there is no slop at the ends of it where the bolts go through? The adjustable replacement probably has solid bushings, are they a tight fight around the bolts at the ends?

I get strange clunk sometime as well. I've replaced everything from Tranny mounts, to rear end mounts and i still get a slight clunk every now and than when i shift "too fast" or while doing to spirited shifting/driving. This clunk has led me to bielieve that it is either my Driveshaft u-joints or some other part of the rear suspension. I am currently saving a couple hundred $$$ to replace every bushing in the rear end. Any recommendations on bushing company's.. poly/rubber replacements. Also I just recieved my tokico HP non adjustable suspension (full set) in the mail. I have not chose springs. my questions : Do they HAVE To be tokico springs to fit on the tokico struts?

Since apex13b is the only one who has recognized the camber links importance, I think I'm doing a bad job of explaining it, I was bored so I drew a silly illustration.
Maybe someone will find it useful. This is from my memory, which is not very good, so please excuse any gross inaccuracies, I'm not an artist either

Why there is a slip yoke on the driveshaft?
Well, when the rear axle articulates, the distance between the diff and the tranny changes.
Oops, sorry, thinking about my truck
The engine/tranny assembly can move forward/back slightly under tourque, you need a slip assembly between that moving assembly and the static rear diff, or you'll start damaging the pinion bearings in the diff. You only need a little bit of slip, but it's easier to make a longer slip that also seals the rear of the tranny, rather than put a flange on the tranny and have a slip within the driveshaft.
I'll PM my address
EDIT: Oh, and what kind of play do you have at the tranny? Do you mean it can slip in and out (OK) or that there is lateral play in the slip (not OK). If the latter, then you have wear in the tranny rear seal, and that could very well be your clunk.

I do get up/down & side to side play at the yoke. Maybe that's the prob. I'll replace the seal. (doesn't leak) I have a new one on hand to... I got it for when I put the other drive shaft in, incase the old one started to leak. I'll pop it in and see.
I thought for sure it was the front u-joint before I replaced it w/ a diff shaft cuz, I get most of the clunk in lower gears and from a stop. Going from 3rd to 4th then 5th doesn't make the clunk.

I had to open the mounting points a tad, to get the ends to go in. It's stout.

No, I don't think you HAVE to use tokico springs with their struts.
