This 2001 Chevrolet Silverado was binding during tight turns with Auto 4WD selected. These shop photos document the automatic transfer case rebuild at AMR Automotive.

The sequence shows the transfer case removed and the housing opened, followed by views of the chain, clutch pack and clutch plates. Other images show assembly tooling used during the job.
