Timken 513186 Wheel Bearing and Hub Assembly - Front or Rear

Timken 513186 Wheel Bearing Hub Assembly

Timken 513186 is a wheel bearing and hub assembly built for front and rear applications on select Cadillac, Buick, Chevrolet, and Saturn vehicles. It is engineered for low runout, stable wheel-speed sensing, and consistent hub performance in everyday driving.

Key Features

• OE-developed testing helps control design, materials, and manufacturing process
• Low runout construction helps reduce noise and vibration
• Premium seals use reinforced and contamination-resistant features to support sealing life
• Precision-profile bearings with uniform internal geometry support load capacity and bearing life
• ABS sensor is 100% tested for wheel-speed monitoring in Anti-lock Braking Systems
• 5 wheel studs, 3 flange bolt holes, and a 115.00 mm bolt circle diameter
• Wheel pilot diameter: 70.10 mm; hub pilot diameter: 91.42 mm

Detailed Description

This Timken hub bearing assembly is a non-driven wheel hub designed for direct replacement in select GM platforms. The assembly uses precision bearing surfaces and controlled internal geometry to support smooth rotation, braking consistency, and efficient wheel-speed signal performance. Timken 513186 is a strong match for drivers searching for a front wheel bearing hub assembly for 2003-2007 Cadillac CTS, a front hub assembly for 2005-2011 Cadillac STS non Brembo brakes, or a rear hub bearing assembly for 2005 Buick Terraza, 2005 Chevrolet Uplander, and 2005 Saturn Relay with independent rear suspension.

This part cross-references SKF BR930298 and Monroe Shocks & Struts 172286 for the same application.

What It Helps Address

• Wheel bearing noise from worn or rough internal bearing surfaces
• Steering wheel or chassis vibration related to hub runout
• ABS warning lights caused by inaccurate wheel-speed signal output
• Uneven braking feel linked to hub instability
• Excessive wheel play from a deteriorated hub bearing assembly

Installation Notes and Fitment

Compatible With:

• Fits 2005-2011 Cadillac STS, Front, Non Brembo Brakes; 5 Stud
• Fits 2003-2007 Cadillac CTS, Front
• Fits 2005 Buick Terraza, Rear, Independent Rear Suspension - Triangular Flange
• Fits 2005 Chevrolet Uplander, Rear, Independent Rear Suspension
• Fits 2005 Saturn Relay, Rear, Independent Rear Suspension - Triangular Flange

Verify flange offset, bolt circle diameter, and pilot dimensions before installation. Confirm ABS connector and sensor alignment during replacement, and inspect the mating surfaces for corrosion or damage so the hub seats correctly.

Quality Assurance

Timken hub assemblies are manufactured using OE-developed test standards and controlled production methods to support consistent fit, sealing, and bearing performance. The ABS sensor is individually tested for wheel-speed monitoring accuracy.
