Key Features

• OE-developed testing used to control design, materials, and manufacturing process
• Low runout construction to reduce noise and vibration
• Premium bearing profiles with uniform internal geometry and enhanced surface finish
• Premium seal design with reinforced outer case, ribbed inner diameter, and contamination exclusion features
• ABS sensor is 100% tested to monitor wheel speed for Anti-lock Braking Systems
• Non-driven rear hub assembly with 5 wheel studs and 4 flange bolt holes
• Cross-reference: SKF BR930026 for the same application

Detailed Description

This Timken wheel bearing and hub assembly is designed around OE-style engineering controls to help maintain consistent fit and performance. The hub uses precision bearing geometry and improved surface finishes to support load capacity, bearing life, and fuel efficiency, while the low-runout design helps reduce brake pulsation, road noise, and vibration. Timken 513018 also includes an ABS sensor that is tested for wheel-speed monitoring, making it a practical replacement for rear hub service on vehicles such as the Chevrolet Lumina, Pontiac Grand Prix, and Buick Regal.

Compatible With rear hub replacement needs on 1983-2001 Buick Century, Regal, LeSabre, Riviera, Reatta, and related models; 1985-1990 Cadillac DeVille, Eldorado, Seville, Fleetwood, and Commercial Chassis; 1984-2001 Chevrolet Celebrity and Lumina; 1983-1993 Oldsmobile Cutlass Ciera, Cutlass Cruiser, Cutlass Supreme, Omega, 88, Delta 88, 98, and Toronado; and 1985-1996 Pontiac 6000, Bonneville, Grand Prix, and Trans Sport applications.

Common Problems This Part Can Address

• Rear wheel bearing noise or growling
• Excessive wheel vibration or runout
• ABS wheel-speed signal faults from a worn hub assembly
• Brake feel issues related to hub instability
• Loose or rough rear wheel rotation

Installation Notes and Tips

• Verify rear fitment by year, make, model, and brake configuration before ordering.
• Confirm the 4-bolt flange pattern, 5-stud wheel mounting, and non-driven rear application match the original part.
• Inspect the knuckle, axle area, and mating surfaces for wear or contamination before installation.
• After installation, check for proper wheel-speed sensor operation and confirm there is no abnormal noise or play.

Quality Assurance

Timken uses OE-developed testing and controlled manufacturing processes for hub bearing assemblies. The design emphasizes low runout, sealed contamination protection, and tested ABS sensor performance to support consistent operation in service.
