Detailed Description

This Dorman axle shaft assembly is made for select front left inner driveline applications on Cadillac Escalade, Chevrolet Silverado 1500, Tahoe, Suburban 1500, Avalanche, and GMC Sierra 1500, Yukon, and Yukon XL 1500 models. It is intended as an OE-style replacement for vehicles with the listed spline and differential specifications, helping restore proper axle function when the original shaft is damaged or the bearings are worn. Dorman 630-420 is supplied as an outer axle shaft and uses carbon steel construction for the specified application.

This part cross-references GM applications such as 26058813 and GM8.25FAX-001 for the same application.

What It Helps Fix

  • Broken or bent front axle shaft components
  • Noise or vibration from worn axle-related parts
  • Driveline issues caused by damaged inner splines
  • Loss of proper front axle engagement in the listed 4x4 setups
  • Service needs after differential or axle wear

Installation Notes and Tips

Verify the vehicle’s year, make, model, front left inner position, RPO axle ratio, and differential casting number before installation. This axle shaft assembly does not include wheel studs, hub bearing, axle shaft seal, brake hardware, brake dust shield, brake backing plate, or ABS tone ring. Confirm the 28-spline inboard configuration and 6x5.5 wheel bolt pattern match the original setup before assembly.
