Product Details

The American Axle & Manufacturing (AAM) 15552845 is a genuine OEM pinion end yoke washer designed for the GM 10.5" 14-bolt rear differential. This hardened steel washer seats between the pinion nut and the companion flange (end yoke), ensuring proper clamping load and preventing the nut from backing off under load. It is a critical component during any ring and pinion swap, yoke replacement, or pinion seal service.

Key Specifications:

  • Outside Diameter (OD): 47mm (approx. 1.85")
  • Inside Diameter (ID): 24mm (approx. 0.94")
  • Thickness: 5mm (approx. 0.197")
  • Genuine AAM OEM part — same washer used in original factory assembly
  • Replaces alternate part number 74002845

Key Features:

  • Genuine AAM OEM quality — not aftermarket
  • Designed for use with pinion nut AAM 15552844 (sold separately)
  • Essential component for pinion seal kits and differential rebuild kits
  • Ensures correct pinion bearing preload and yoke retention
  • Compatible with 1988 and newer GM 10.5" 14-bolt rear axle applications

This washer is included in AAM differential rebuild kits such as the AAM 74010014 and various pinion seal kits, but is also available individually as a replacement. It pairs directly with AAM pinion nut 15552844 for a complete pinion fastener set. Cross-reference part numbers: 15552845 (AAM), 74002845 (alternate AAM number).

Shipping too expensive!

Quick shipping, great product

Thank you. You are cheaper than West Marine Pro, (although I have to pay shipping,) and faster than Amazon. My poor planning of immediate boat projects, and your products and ease of ordering and two day delivery work well.
