No crush sleeve on the H052 or HO72 Eaton. The center spacer for the pinion bearing is matched to the two bearings so that when its assembled the yoke applies force against the center race and the retainer forces the outer race against the shims in the carrier housing creating preload. The shims are used to set the pinion depth which establishes the mesh pattern with the ring gear. Backlash is adjusted using the adjusters. I strongly caution against attempting to do a rebuild without the benefit of a shop manual. Below is a helpful link:
