Whenever I'm driving, I can hear some brushing sounds from the rear. If I am in gear and applying gas, it gets a bit louder, although while in neutral coasting to a stop the brushing sound can still be heard. It seems to be dependent on rpms...

Re: Is my diff about to grenade?
Sounds like the rear end is going, I would check your pinion nut to see if its backed out,might need to re TQ it to spec.08' L76 6.0L 4X4 Chevy EXT.Cab LTZ Vortec MAX with Snug top cover, Dynomax exhaust,Hptuners& K&N intake

Re: Is my diff about to grenade?
define brushing? like a piece of metal is spinning and something is touching it? where is it coming from? my tranny tailshaft is making that noise? I think I cracked my tailshaft...maybe you're in the same boat?

Re: Is my diff about to grenade?
Brushing...like a stiff brush over metal sound.
I did have the diff fluid changed out about 500 miles ago, noise started after that. Makes me wonder about how good a job they did.Last edited by enzia35; 03-10-2012, 09:29 PM.Comment

Re: Is my diff about to grenade?
My guess is the pinion bearing. Mine is making the same noise.Comment

Re: Is my diff about to grenade?
Did you isolate where the noise is coming from? put it on a hoist or stands, and find out where the noise is coming from...sounds very similar to the sound coming from my tailshaft...
