What It Helps Repair

Installation Notes and Tips

Confirm the transfer case model before ordering, since this kit is listed for 261HD and 263HD heavy-duty applications. Inspect the housing, shafts, and mating surfaces during disassembly so the new bearings and seals can seat correctly. Clean all sealing surfaces thoroughly before assembly, and verify that the replacement components match the original dimensions and bearing type.
