Chevrolet Avalanche Transfer Case Seal

The Transfer Case Seal for the Chevrolet Avalanche keeps lubricant inside the transfer case so the gears can remain cooled and protected. Positioned around the output shaft, this Transfer Case Seal does not allow leakage of fluid, which would drop the fluid levels leading to overheating, gear wear, and weak power delivery. While driving, pressure and rotation of the shaft push outward on the fluid. The flexible lip of the Transfer Case Seal grips the shaft, and the metal case of the seal is anchored in the housing. A failed seal leads to puddles under the case and drips down the driveshaft. Replace the Transfer Case Seal before losing fluid damages synchronization between the transmission and the transfer gears. The majority of the production run, Avalanche models use this one radial-lip style. As such, the differences center around minor diameter changes that suit specific driveline options rather than distinct types. Thus, replacement procedures are the same on any Chevrolet 4x4 built on an Avalanche chassis. The prompt installation of a new Transfer Case Seal with inspection of the supporting bushing to ensure that the shaft sits centered will preserve smooth operation and extend the life of every Chevrolet drivetrain.

Each OEM Chevrolet Avalanche Transfer Case Seal we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
