I own a 1995 2 dr chevy blazer and when ever i make left hand turns at speeds over 30-35 mph ther is a clunking noise that comes from the back of the truck. Then when the turn is over there is no longer the clunking. Any ideas on the problem it will be helpful.

 

Do you have a locker or limited slip in the rear axle?

 

limited slip,,my o5 does the same thing

 

Definitely sounds like something is amiss in the rear diff. I'd pop the cover to make sure that nothing is broken. I don't think a properly working limited slip (posi) should make clunking noise while turning.

 

It is a limited slip diff and i have already pop the cover off and looked at the inside and everything seemed to be ok. You guys have any more ideas becuase i can't think of anyhting other things that coudl be wrong with it. thanks

 

Can you "feel" the clunk while driving? Check the sway bar links, bushings, where the links mount to. Such as the frame. Look for broken bolts. Check to the leaf springs, U bolts, the entire rear suspension for any thing broken/ out of wack. Oil up the leaf spring shackles.

Jump up and down on the rear bumper, may hear something there. Check the spare, make sure its snug. Not swaying.

 

I can kinda of feel the cluncking when driving. I looked at the suspension and every thing is ok. I oiled and greased the suspension parts and it helped. Could that have been the problem or could there still be something else that could be broken. Thanks for teh help.

 

You may want to check the torsion bar crossmember to see if it has been hitting the frame.

 

I had this exact same problem with my blazer and I just got it fixed yesterday. The torsion bar mount needs to be replaced, it's probably almost completely deteriorated. Take a crow bar and pry up on the mounts, if it moves you've found your problem.
