I have a small issue with my 2000 Blazer 4x4. I occasionally get a loud clunking sound from the drivers side when turning sharp right onto an incline. Sounds very similar to a worn out CV joint. However both driveshafts and all control arm ball joints have been replaced, so that would rule those out. Passenger side wheel bearing was replaced. Drivers side bearing ok.

Any suggestions as to what could be causing this?

 

Broken sway bar end link. Broken torsion bar crossmember mount. Any one, or more, of the 8 control arm bushings worn out.

 

check upper control arm mount bolts...

I had a VERY similar sound under similar circumstances a while back, ended up being the rear most upper control arm bolt/nut being loose, almost hand tight... Not sure how it backed off, but it was letting the control arm move all over the place in the rear mount. I tightened it down (had an alignment done shortly after as well, but I also replaced ball joints), and told them to pay special attention to the upper bolts and make SURE they were tight...
