Detailed Description

Timken HA598679 is engineered for front axle service on 1999-2004 Jeep Grand Cherokee models. The hub assembly uses precision-machined bearing surfaces, enhanced surface finishes, and controlled internal geometry to support load capacity and bearing life while helping maintain smooth operation. Its low-runout design helps reduce brake pulsation, wheel-end noise, and vibration, which is important on a front hub assembly that also supports braking and ABS function. This part cross-references SKF BR930335 for the same application.

What It Helps Solve

• Front wheel bearing noise or growling
• Wheel-end vibration during driving or braking
• ABS wheel-speed signal faults tied to the hub sensor
• Excessive hub runout affecting brake feel
• Wear-related looseness in the front wheel end

Installation Notes and Tips

Verify spline count, bolt circle diameter, flange offset, and pilot dimensions before installation. Clean the mounting surface thoroughly and inspect the axle, knuckle, and brake components for wear or damage before fitting the new hub. Confirm ABS connector routing and sensor alignment during installation, and torque fasteners to the vehicle manufacturer’s specifications.

Quality Assurance

Timken uses OE-developed testing to control the design, materials, and manufacturing process for its hub bearing assemblies. The result is a front wheel bearing and hub assembly built with premium seals, precision bearing profiles, and 100% tested ABS sensors for dependable wheel-speed monitoring on Jeep Grand Cherokee applications.
