Installation Notes and Tips

Verify the axle and ring gear size before ordering, since this kit is listed for front 8.25 in. ring gear applications. Confirm the vehicle year, model, and front position against the fitment table, especially on Chevrolet Tahoe, Chevrolet Suburban 1500, GMC Yukon, GMC Yukon XL 1500, and Cadillac Escalade variants. Timken markets DT Components rebuild kits as bearing-and-seal service kits, and DRK321T is the standard kit version.
