Mercedes Sprinter Rear Driveshaft Center Support Bearing – OEM | NCV3 | #9064100381 (2006–2018)

DESCRIPTION:

A worn rear driveshaft center support bearing is one of the most reliable sources of driveline vibration on a high-mileage NCV3 Sprinter — and because it develops gradually, it's often attributed to other causes before the bearing is finally identified. When the rubber isolator cracks or the bearing wears, the rear section of the two-piece driveshaft loses its center support, introducing a vibration that worsens with speed and load. This OEM-spec replacement restores proper driveshaft alignment and eliminates vibration at the source.

What This Part Does

This is the rear center support bearing in the NCV3 Sprinter's two-piece driveshaft system. It mounts to the chassis and supports the driveshaft at the midpoint between the transmission and the rear differential, maintaining alignment and absorbing driveline vibration through a rubber isolator. This rear variant features a 3mm spacer at the mounting holes — an important dimensional difference from other bearing variants in the same family. Always verify your exact part number before ordering.

How It Differs from 9064100281

The NCV3 Sprinter driveshaft uses multiple center support bearing variants depending on wheelbase, configuration, and production date. The 9064100281 is the front support bearing; this 9064100381 is the rear unit with the 3mm mounting spacer. They are not interchangeable. Always verify your VIN and existing part number before ordering.

Common Symptoms of a Failing Center Support Bearing

• Vibration felt through the floor or seat, especially under acceleration
• Humming or rumbling noise that changes with vehicle speed
• Clunking from underneath when engaging drive or reverse
• Visible cracking or deterioration of the rubber isolator

When to Replace

Replace at the first sign of driveline vibration or rubber deterioration. Always replace the driveshaft flex discs (guibo) at the same time — these components wear together and replacing just one often leaves the other near end of life.
