Transmission & xDrive

Propeller-shaft center support

Supports a multi-section propeller shaft while isolating vibration.

Where it sits

Around the intermediate shaft section under the car.

How it works

A rolling bearing and resilient mounting locate the shaft while allowing its intended movement.

Think of it as

A cushioned support halfway along a spinning pole.

Symptoms when it fails

Vibration under load can involve the support, shaft alignment, joints or mounts.

Lifespan

Use the exact gearbox and axle service guidance. Loads, seals, lubricant condition and driving use influence wear.

Repair cost

An accessible mount or seal differs from internal transmission work. Gearbox identification and diagnosis are essential to a useful quote.

The BMW angle

BMW shaft service can require attention to assembly position and preload specified for that drivetrain.

Used in

BMW rear-drive, front-drive and xDrive applications as equipped; layouts differ by platform.
