VAICO V20-8140 Drive Shaft Center Support Bearing Propshaft Mounting

The VAICO V20-8140 is a replacement drive shaft center support bearing and propshaft mounting assembly, designed to restore proper driveline alignment and eliminate vibration caused by a worn or failed original unit. This part replaces OEM reference number 26127513218 (also cross-referenced as 26127507318).

The propshaft center support bearing — also known as a driveshaft center support, carrier bearing, or CSB — is a critical driveline component. It mounts to the underside of the vehicle's chassis and holds the two-piece driveshaft in proper alignment. The rubber-isolated bearing absorbs vibration and prevents noise from transmitting into the cabin. Over time, the rubber isolation element can dry rot, crack, or collapse, leading to driveline vibration, clunking, or accelerated wear on adjacent driveline components.

Key Features:

• Direct OEM replacement for propshaft center support bearing
• Replaces BMW OEM part number 26127513218 and 26127507318
• Rubber-isolated bearing design absorbs drivetrain vibration and reduces NVH (noise, vibration, and harshness)
• Restores correct driveshaft alignment between the transmission and rear differential
• Manufactured by VAICO to OE-equivalent quality standards

Symptoms of a failed center support bearing include driveline vibration felt through the floor, clunking during acceleration or deceleration, and unusual noise from beneath the center of the vehicle. Replacing this unit with a quality part like the VAICO V20-8140 is essential to maintaining smooth, vibration-free driveline operation.
