Detailed Product Description

The Timken SP940203 is a wheel bearing and hub assembly designed to meet the exacting standards required for non-driven axle setups. Its 10-wheel stud configuration and 4-flange bolt holes provide a secure and stable connection between the wheel and hub. The assembly’s multiple pilot diameters ensure compatibility with both wheel and brake components, facilitating proper alignment and reducing vibration. The flange offset and diameter are engineered to maintain the correct wheel positioning relative to the suspension and brake system, which is critical for vehicle safety and handling.

Compatible Vehicles and Applications

This wheel bearing and hub assembly is compatible with a range of vehicles requiring a non-driven axle hub with a 10-lug wheel stud pattern and specific flange and pilot dimensions. It is commonly used in trucks and SUVs where precise fitment is essential for wheel and brake system integrity. The part number SP940203 is referenced for fitment in applications requiring a 170 mm bolt circle diameter and a 203 mm flange diameter.

• Resolves wheel vibration and noise issues caused by worn bearings
• Addresses wheel hub looseness and play affecting steering stability
• Corrects brake rotor misalignment due to damaged hub pilots
• Prevents premature wheel stud failure and wheel detachment risks
• Supports proper wheel mounting on non-driven axles with 10-lug configurations

Installation Notes and Tips

Ensure the vehicle is securely lifted and supported before beginning installation. Clean the hub mounting surface thoroughly to remove rust and debris. Verify that the flange bolt holes and wheel studs align correctly with the vehicle’s wheel and brake components. Use a calibrated torque wrench to tighten flange bolts and wheel studs to manufacturer specifications to avoid over-tightening or under-tightening. Inspect the assembly for smooth rotation and absence of play after installation.
