I've got the Dana 35 rear. Well i replaced the brakes about a 2 months or so ago and for some reason i'm having like a grinding sound coming from the rear. The faster i go the more you can't hear it but if you coasting about 10-20 you can really hear it. Any ideas? Maybe the Diff or brakes.

 

been mudding? you might have mud in your rear brakes. take the drums off and confirm every thing is ok back there.

 

Sounds like the shoes didn't get adjusted enough.

 

sounds like a spring came loosse,

 

The adjuster cable may have come off and is rubbing on the drum. Have you even taken the wheels off to see what it may be?
