What It Helps Address

• Front wheel bearing noise or growling
• Wheel vibration caused by hub runout
• ABS warning light concerns related to wheel-speed sensing
• Loose or unstable front wheel-end feel
• Reduced braking consistency from worn hub components

Installation Notes and Tips

Verify spline count, bolt pattern, flange offset, and pilot diameters before installation. Confirm front-position fitment for the specific Ram model and trim, including Mega Cab applications where listed. Inspect the mating surfaces, axle interface, and ABS connector condition during replacement to help ensure proper seating and sensor operation.

Quality Assurance

Timken manufactures hub bearing assemblies using OE-developed test procedures and controlled production standards. The assembly includes premium seals, precision bearing geometry, and a tested ABS sensor to support reliable wheel-end performance.
