yeah i would check that out, ive gone through two rears, one i would hear a hum as i drive down the highway over 55, then nest i burnt out and the carrier was wasted, it was burned and the gear oil was black, also the retainer pin was slit and pushed out a bit, and that could be it, ur gears might be lose and moving around in there
this is the one that the bearing shaft broke off, but my other lost the shaft that holds the gears in when i burnt it out and yes your clutch could be burnt out and making that nosie cause mine was making that noise
does it make any noise when stoping and going?
