GM-29369-2 - The output shaft on the right side of the PTU is supported by a needle bearing inside the ring gear hub. The diameter of the hub prevents needle bearing removal using conventional methods, i.e., hammer and brass drift. GM-29369-2 is placed through the needle bearing, and its thumb screw is tightened to expand it under the needle bearing race. GM-02619-A Slide Hammer is attached to GM-29369-2 and used to remove the needle bearing without damage to the ring gear hub.
