clunk on decel

Just got this 2000 today with 141k on it. I notice a few times under decel i get a hard clunk somewhere in the driveline. I have to get the u-joints checked, but is there anything else i should have checked? I suppose there is some slack in the rear end, but i have never had one backlash that bad.

Yeah believe it or not it was the rear right brake rotor. The dealer had replaced the front rotors but the RR was still warped. So i replaced it and add a little more fluid and walla! Fixed. I don't exactly know if it just needed more fluid for the rear caliper or if the warped rotor was the cause, it was very bad.

You maY need to grease the driveshaft behind the carrier bearing where it slides in and out. Mine would bump reall bad on decal and that solved the problem for me. There is a write up somewhere on the forum that I used.
