Detailed Description

Mahle P27857TC is an axle housing cover gasket for rear differential service on a wide range of GM trucks, SUVs, and vans. It is listed for vehicles such as Chevrolet Silverado 1500, GMC Sierra 1500, and Cadillac Escalade rear axle applications, along with many earlier Chevrolet and GMC light-duty platforms. The cork with metal carrier design helps maintain gasket shape during installation and service, while the OEM standard grade supports a direct replacement approach for axle cover resealing.

Mahle gaskets are used by technicians and OEMs around the world, and this part follows that sealing-focused approach for rear differential maintenance. If you are servicing a leaking axle cover on a Chevrolet Tahoe, GMC Yukon, or similar 10-bolt rear axle setup, P27857TC provides the correct sealing profile for the specified ring gear and bolt-hole pattern.

What It Is Used For

• Rear differential cover leaks
• Gear oil seepage at the axle housing cover
• Service replacement after axle inspection or fluid change
• Sealing wear on 10-bolt rear axle housings
• Restoring a proper seal on compatible Chevrolet and GMC rear ends

Installation Notes and Tips

Clean both mating surfaces thoroughly before installation and remove all old gasket material, sealant residue, and debris. Verify the axle cover pattern, ring gear size, and rear position against the vehicle notes before assembly. Tighten cover fasteners evenly in a crisscross pattern to help seat the gasket uniformly and reduce the chance of leaks.
