Transfer case noises

[Dirtautoguy]

On my 96 chevy k1500 if I jack the front tire off the ground and spin it backwards it clicks but not spinning forward. It sounds like its coming from the t case and I can't hear it while I'm actually driving in reverse is it supposed to be that way?

I wouldn't think there should be a clicking noise, but its hard to say. Hard to relate to noises without hearing them.

Do you happen to know where the noise is coming from. May have a bad bearing or CV joint.

Well both of the wheel hub assemblies are new and one cv joint is newer and it sounds like its coming from the transfer case and does it on both sides.

The two most common problems I was told are the oil pump has a little metal clip that grinds thru the case and the chains stretch.
