    Finally got the K5 driving and noticed, I guess, the rear u-joint vibe ("humm" starting at about 30MPH). Installed the TC 4" tapered lift blocks for lift in the rear, shouldn't these help? The short end of the block should be towards the front, right? The pinion angle doesn't look as extreme at the axle as at the case. What next???

    Make sure the two angles are the same. Ultimately, most likely, lowering your transfer case.

    How far is it safe to lower it? Do I just put spacers between the frame and the support??
