CTSSS Posted November 24, 2010 Report Share Posted November 24, 2010 Hey guys. Well recently i have been hearing a clunking noise coming from my truck. It only seems to happen when i am going down hill, generally when i let off the brakes and the engine is slowing the truck down. Any ideas on what it could be?

CTSSS Posted November 24, 2010 Author Report Share Posted November 24, 2010 im at just over 80k, how bad is that and will it help if I change the fluids? Quote Link to comment Share on other sites More sharing options...
70chevy03ss Posted November 24, 2010 Report Share Posted November 24, 2010 If you change your fluids and chunks come out it means your diff is junk. Mine did the clunk and what not till it just stopped dead. Quote Link to comment Share on other sites More sharing options...

CTSSS Posted November 25, 2010 Author Report Share Posted November 25, 2010 Noise seems to be coming almost from right under my feet, so front diff? Quote Link to comment Share on other sites More sharing options...
