Detailed Description

Timken 512002 is a rear hub bearing assembly for Saturn SC1, SC2, SL, SL1, SL2, SW1, and SW2 applications. The assembly uses precision bearing profiles and controlled internal geometry to support smooth rotation, while the low-runout design helps reduce vibration and braking noise. Timken also integrates a tested ABS sensor to monitor wheel speed for Anti-lock Braking Systems. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Rear wheel noise from worn hub bearings
• Vibration felt through the chassis or during braking
• ABS warning concerns related to wheel speed signal loss
• Excessive wheel-end play or rough bearing rotation
• Seal contamination that shortens bearing service life

Installation Notes and Tips

Confirm rear fitment by year, model, and position before installation. Inspect the knuckle, axle interface, and ABS wiring condition during replacement, and clean the mounting surfaces so the hub seats evenly. Proper torque and a careful sensor connection are important for stable wheel speed readings.

Quality Assurance

Timken uses OE-developed test procedures to validate the design, materials, and manufacturing process behind this hub assembly. The result is a wheel-end component built to meet the demands of daily driving on compatible Saturn rear applications.
