Hey all,

Getting a groan from my jeep when in 4wd, only does it under acceleration. The unis in the shaft are near new, and it makes a high pitch buzzing/grind when foot is flat in 4wd (can be 4low, hi or part time), and the noise is heinous when in 4part time in the wet at about 60kmh.
Tcase or front diff?

Should I drop the shaft and see if it still does it? It is load based so idk if it'll still be prevalent when you take the shaft out...

Cheers
