So I just grabbed the rear driveshaft and there is no play in it, side to side and up and down it is solid. If you try to spin it, the play is in the t-case/rear axle not in the u-joints. Is it possible it is still the U-joints on the driveshaft. My front drive shaft was redone about a year ago, since the slip joint in it seized.
How do you check the unit bearing? Also if it is in the front driveline, why would it chirp in 2wd only when accelerating/going up hill? I never get the noise if I am holding a constant speed on flat ground or decelerating. The front driveline should have no load on it in 2wd.
