Description
81394106037 Center Support Bearing — Multiple Semi Truck series, 2.362″ inner dia | 3.750″ center-to-base | 8.625″ mount spacing. Professional replacement. Verify inner dia and mount spacing.
Full Description
The 81394106037 center support bearing supports the midshaft section of a two-piece driveshaft, keeping it running concentric with the vehicle's drivetrain axis. When this bearing fails, the midshaft droops and the driveshaft angles change — you'll feel it as a vibration that gets progressively worse at highway speed. The 81394106037 center support bearing is the correct replacement for Multiple Semi Truck series applications, with the exact inner diameter and mount hole spacing your application requires.
81394106037 Center Support Bearing — Multiple Semi Truck Series Dimensions & Mount Specs
The 81394106037 center support bearing specs: 2.362" inner dia | 3.750" center-to-base | 8.625" mount spacing. Fits multiple semi trucks Bearing: 70x25. Application: Multiple Semi Truck series. Inner diameter must match the midshaft stub OD exactly — a loose fit allows the bearing to walk on the shaft, which causes vibration and accelerates wear on both the bearing race and the shaft surface. Mount hole center-to-center spacing must match your crossmember bracket.
When replacing a center support bearing on a two-piece shaft, replace the complete assembly — bearing race, rubber isolator, and bracket together. A new race in an old hardened rubber mount still vibrates. The rubber isolator is what actually absorbs the midshaft movement; without it the bearing transmits every frequency directly to the frame.
