3580-40 – Center Support Bearing – Nissan Application – 1.574″ ID – 2.250″ Center Bearing To Base

The 3580-40 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 3580-40 center support bearing is the correct replacement for Nissan series applications, with the exact inner diameter and mount hole spacing your application requires.

3580-40 Center Support Bearing — Nissan Series Dimensions & Mount Specs

The 3580-40 center support bearing specs: 1.574" inner dia | 2.250" center-to-base | 6.665" mount spacing. rubber cushion w/o canister. Application: Nissan 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.
