Dorman Drive Shaft Center Support Bearing for Toyota T100/Tacoma/Tundra — Direct Replacement, Vibration Reduction

The Dorman 934-401 drive shaft center support bearing is a direct-replacement bearing engineered to restore proper drive shaft support and reduce drivetrain vibration on compatible Toyota trucks.

This center support bearing is crafted to match the fit and basic function of the original equipment bearing for selected Toyota T100, Tacoma and Tundra model years. Built with rugged materials and Dorman’s quality control, the part is intended to return smooth drive shaft operation after the factory bearing wears or fails. Before ordering, use the vehicle lookup tool to confirm compatibility for your exact trim and model year.

How does this bearing restore drive shaft performance?

When a center support bearing fails it allows extra movement and vibration in the drive shaft, which can cause noise and uneven wear. Replacing the worn bearing with a correct-fit unit stabilizes the shaft, reduces vibration, and helps maintain proper alignment of driveline components.

• Matches original mounting points and basic dimensions for listed Toyota models
• Re-centers the drive shaft to reduce vibration and drivetrain noise
• Replaces worn rubber and bearing elements to prevent premature wear elsewhere

What materials and construction features does this unit use?

This part is manufactured from quality materials chosen for strength and longevity under load. The bearing inner race and rubber isolation elements are selected to resist fatigue and handle typical highway and light off-road use found in trucks.

• Durable bearing race and sealing for long service life
• Robust rubber housing to absorb road shock and reduce vibration
• Corrosion-resistant surfaces for extended durability in varied conditions

How do I confirm fitment for my vehicle before buying?

Use the site’s garage or vehicle lookup tool and enter your year, make, model, and trim to check confirmed fitment. If an information icon appears, hover or click it to view additional notes that can affect compatibility—such as specific axle or drive configurations.

• Enter exact model year and trim in the garage tool to check the Confirmed Fit bar
• Look for an "i" icon for additional fitment notes and verify those match your vehicle
• Contact customer support with VIN details if fitment remains unclear

What installation or maintenance tips should I know?

Center support bearing replacement often requires basic driveline disassembly and proper torqueing of fasteners during reassembly. Inspect adjoining universal joints and mounting hardware while the shaft is removed to avoid redoing the job shortly after installation.

• Follow vehicle service manual for shaft removal and alignment procedures
• Replace worn U-joints, bolts, or mounts discovered during inspection
• Torque mounting hardware to manufacturer specifications for secure fit

Who is this for: The Dorman 934-401 center support bearing is intended for owners and technicians working on Toyota T100 (1993–1998), Tacoma (1995–2012) and Tundra (2000–2006) vehicles who need a direct-replacement bearing to restore driveline stability. It’s a practical choice for DIY mechanics, fleet maintainers, and independent shops seeking a dependable, vehicle-specific replacement part. Always confirm your vehicle’s fitment using the lookup tool or your VIN before purchase to ensure correct application and avoid returns.
