I've been noticing for a while that my rear diff makes a noise whenever I am turning. Sort of like a locker in a jeep or something will whenever it turns. It's been doing this for a while but seems to have maybe gotten a little worse. I've been trying to go over it lately and replace the basic essentials..bushings, joints, etc. and figured I might as well look into this while I'm at it. Anyone have any input or advice?
