hello everyone I just got my first Cherokee 94 country it has the 35 dana rear with trac lok 3.55 some mystery noise a crunching at slow speed only, rotational once per wheel rotation, and am thinking of swapping it out .of course will pull cover but new to inspecting any tricks to finding fail point? u joints seem ok wheel bearings also ok to my knowledge .
a guy local has a dana 30 front and Chrysler rear axle out of a 94 sport but have 308 gears and not sure of the rear interchangeability any advise is appreciated thanks

just pulled cover seems ok found weeping passenger side seal slight very slight play in bearing so am going to pull axle don't have bearing puller though
