Description

Visco Unit Bearing for the rear propshaft, supporting the viscous coupling unit (VCU) in the four-wheel-drive driveline.

The bearing locates on the propshaft alongside the viscous coupling unit, holding it in position so it rotates smoothly while drive passes through the VCU to the rear axle. A bearing sits on each side of the coupling and they are normally renewed as a pair; a worn bearing typically shows up as driveline whine and vibration under load.
