Overview of Dorman 630-420 Drive Axle Shaft Assembly

The Dorman 630-420 drive axle shaft assembly is engineered for reliable performance in select GM trucks and SUVs. Designed specifically for models like the Chevrolet Silverado 1500 and GMC Sierra 1500, this axle shaft provides a precise fit and durable construction to maintain driveline integrity.

  • Compatible with 6x5.5 wheel bolt pattern vehicles
  • Constructed from carbon steel for strength and durability
  • Inboard spline quantity: 28 for secure engagement
  • Shaft diameter measures 1.25 inches for proper fitment
  • Designed for independent front suspension (IFS) differential case design
  • Includes outer axle shaft only; no wheel studs or brake components included
  • Compressed and overall length of 5.04 inches

Detailed Product Description

The Dorman 630-420 drive axle shaft assembly is built to meet the specifications required by various Cadillac, Chevrolet, and GMC models, including the Escalade, Tahoe, Yukon XL 1500, and Suburban 1500. This axle shaft features a 6x5.5 wheel bolt pattern size and a 14mm wheel stud thread diameter with a 1.5 thread pitch, ensuring compatibility with factory wheel setups. The shaft is made from carbon steel, providing the necessary strength to handle torque and rotational forces while resisting wear over time. The 28 inboard splines ensure a secure connection to the differential, while the absence of outboard splines and additional components like ABS tone rings or brake hardware means this part is intended as a direct replacement for the outer axle shaft only.

Applications and Common Repair Uses

  • Replacement of worn or damaged outer axle shafts on compatible GM trucks and SUVs
  • Addressing axle shaft failure due to wear, bending, or breakage
  • Restoring driveline performance and eliminating vibrations or noises related to axle issues
  • Repairing axle shaft spline damage that affects power transfer
  • Upgrading to a factory-spec axle shaft during drivetrain rebuilds

Installation Notes and Tips

Installation of the Dorman 630-420 axle shaft assembly requires proper tools and mechanical knowledge. Ensure the vehicle is securely lifted and supported before beginning work. Since this part does not include wheel studs, brake hardware, or seals, reuse existing components or replace them as needed. Verify spline alignment carefully during installation to avoid damage. Torque all fasteners to manufacturer specifications and inspect the axle shaft seal and hub bearing condition during replacement.

Quality Assurance and Warranty Information

Dorman manufactures the 630-420 drive axle shaft assembly to meet or exceed OEM standards for fit, form, and function. The carbon steel construction and precise spline counts contribute to reliable performance. While this product does not include a rust-resistant coating, proper maintenance and inspection are recommended to prolong service life. Warranty coverage details should be confirmed at the point of purchase, as they may vary.
