I just noticed while pulling out every once in a while i'll feel a slight rumble or something. I think its coming from the rear. ONly for a second and i have to be pulling out with a fairly sharp left, and sometimes right turn. Also usually when i pull out or say turn sharply, the inside tire will chirp a bit, however, when i feel this rumble, i dont hear the chirp at all. Might this have something to do with the clutches in the rear?

 

Nope u got a gremlin under the bed.
Just kiddin sounds like u got the trac loc rearend
From what I've seen on mine that's typical.

 

Mines started to do that a few times, I think its fine...unless it blows up one day
