Timken 513017K Wheel Bearing and Hub Assembly - Front

Timken 513017K Wheel Bearing Hub Assembly

Timken 513017K is a front wheel bearing and hub assembly built for select Chevrolet Cavalier, Pontiac Sunfire, Buick Skylark, and related GM compact models. It combines OE-developed testing with precision bearing construction to support smooth wheel rotation, stable braking feel, and reduced noise and vibration.

Key Features

• Front driven wheel bearing and hub assembly for select GM applications
• Low runout design helps reduce noise and vibration
• Premium seals use reinforced and contamination-resistant construction
• Precision bearing profiles and uniform internal geometry support load capacity and bearing life
• Enhanced surface finishes help improve efficiency and durability
• ABS sensor is 100% tested for wheel speed monitoring in Anti-lock Braking Systems
• 33-spline design with 5 wheel studs, 3 flange bolt holes, and 100 mm bolt circle
• Cross-references SKF BR930028K for the same application

Detailed Description

Built for front-wheel applications, Timken 513017K is engineered to match the demands of compact GM platforms that use a driven hub assembly. The hub features a 2.244 in. wheel pilot diameter, 2.296 in. brake pilot diameter, 2.894 in. hub pilot diameter, 4.921 in. flange diameter, and 1.749 in. flange offset, with metric equivalents of 57.00 mm, 58.33 mm, 73.50 mm, 125.00 mm, and 44.43 mm. These dimensions support proper fitment on vehicles such as the Chevrolet Cavalier, Pontiac Sunfire, Buick Skylark, and Pontiac Grand Am when matched to the listed applications.

Timken uses OE-developed testing to control design, materials, and manufacturing process for hub bearing assemblies. That approach supports consistent performance, while the low-runout construction helps reduce brake pulsation, wheel noise, and vibration. The sealed bearing design and tested ABS sensor add the wheel-speed monitoring needed for anti-lock brake systems on equipped vehicles. Timken 513017K is a direct-fit service part for drivers replacing a worn front hub on 1984-2005 GM compact cars.

What It Helps Fix

• Wheel bearing noise from the front hub area
• Excessive vibration felt through the steering or chassis
• Brake pulsation related to hub runout
• ABS warning concerns caused by a failing wheel speed sensor
• Loose or worn hub performance on driven front applications

Installation Notes and Tips

• Verify the vehicle’s year, make, model, and front position before ordering.
• Confirm spline count, bolt circle, pilot diameters, and flange dimensions against the original hub.
• Inspect the knuckle, axle, and brake components for wear before installation.
• Clean mounting surfaces thoroughly to help maintain proper hub seating and sensor performance.
• Use the listed fitment for 1984-2005 Chevrolet Cavalier, 1995-2005 Pontiac Sunfire, 1985-1998 Buick Skylark, and other specified front applications.

Quality Assurance

Timken manufactures hub bearing assemblies using OE-developed test procedures that control design, materials, and production methods. The bearing elements use precision profiles and enhanced surface finishes, while the seals and ABS sensor are built and tested to support reliable operation in the specified front-wheel applications.
