Yup that's the one. Nak you could remove the rear shaft, lock your center and see what happens. Or swap in a donor shaft.




That's what she said.

x2 on the cool video

I would toss in another vote for splines on the drive shaft. Each change in direction causes the splines to bind slightly due to wearing and/or lack of lubrication in the slip joint.

If you think it's coming from the front, then pull that drive shaft and do the same test. And then try the rear next if the noise is still there.

Bummer, I was betting on a front CV joint.

So how different is a 100 rear shaft from an 80 rear shaft?

They both feel about the same heavy. But it's not the driveshafts... I spent the last 4 hours on this, had them both off, apart, cleaned splines, greased u-joints, put them back on and the clunk is completely unchanged. In fact it may be a little louder now, as I left my skidplates off until I figure this out.. hmm.

Check out how much grease I was able to squirt out the zirc hole on the rear... I only can take credit for maybe 6 squirts of that.

You can literally feel it under your feet, just when you hit the brake. Two new videos... one from each slider

movie 4

I would say its gotta be the pads then. If you are only hearing it when you press the brakes when changing direction that is the only possibility left I can think of. How was your pinion play?

So if I have too much slop in my pads, how do I get rid of that- bleed it? Or shove more shims in there?

Pinions seem fine, they didn't have any in/out play that I could feel.

I would say its the mounting hardware for the pads. There are tension springs that help keep them centered and absorb the shock of directional change. It's possible it could just be at one of the pads. Wiser techs than I may have other ideas as well.
