1780-20 – 20 – Center Support Bearing – 99 06 Vitara, Tracker Application – 1.181″ ID

The 1780-20 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 1780-20 center support bearing is the correct replacement for 99-06 VITARA, TRACKER series applications, with the exact inner diameter and mount hole spacing your application requires.

1780-20 Center Support Bearing — 99-06 VITARA, TRACKER Series Dimensions & Mount Specs

The 1780-20 center support bearing specs: 1.181" inner dia | 3.898" center-to-base | 6.690" mount spacing. Application: 99-06 VITARA, TRACKER 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.
