As best I can recall, the u-joints aren’t officially serviceable on those. But I worked with a guy that rebuilt them, so if you do enough digging online you might be able to find information on it. There should be a bearing on the output shaft, but I believe the output should always be turning, the rear differential function, at least on newer models, is handled at the differential itself.

A U-joint is basically a metal cross with caps that ride on needle bearings.

Thank you.
Checked the u-joints, both are in good shape(No movement) thus suspecting the outer bearing.
Online suggestions are …….replacing transfer assembly*
