Autopart International 1703-429920 Driveshaft Center Support Bearing

The Autopart International 1703-429920 is a replacement driveshaft center support bearing, also commonly referred to as a carrier bearing or center bearing. This component is engineered to support the mid-point of a two-piece driveshaft assembly, maintaining proper alignment between the transmission and rear differential.

Key Features:

• Direct-fit replacement designed to meet or exceed OE specifications
• Supports the junction of a split driveshaft to reduce drivetrain stress
• Helps minimize vibration and harmonic noise during vehicle operation
• Rubber-isolated bearing assembly absorbs shock and dampens driveline movement
• Built for reliable, long-service performance in demanding conditions

A worn or failed driveshaft support bearing can cause noticeable vibrations, knocking or squealing noises from underneath the vehicle, and — if left unaddressed — progressive damage to surrounding driveline components including U-joints. Replacing the center support bearing restores proper driveshaft geometry and smooth power delivery. This part is manufactured by Autopart International, a subsidiary of Advance Auto Parts and a trusted supplier of premium replacement parts for professional installers since 1957.
