Great pack everything as advertised.. plenty of shims.. Note: these carrier shims fit only on outer race, not under the bearing, and pinion depth shims fit only In the housing, not between the pinion head and bearing.. works for me and I would highly recommend this pack. all fits 97-06 jeep wrangler dana 44 30 spline.

Bearings and bearing cups (races) are 1/8" larger than factory... Waited too long to instal, now outside of return window... Not as advertised!

Inspect your Koyo bearing races. Had a couple with defects that could be easily felt with finger. Quick return though. So that is appreciated. Get Timken instead.
