Consult the Timken application guide or catalog to find the exact part number for your vehicle's year, make and model. For example:
| Year | Make/Model | Timken Part Number |
|---|---|---|
| 2016-2020 | Toyota Tacoma | SP500310 |
Verify Dimensions
Use a caliper to measure the critical dimensions of your vehicle's wheel hub assembly mounting points. Key measurements include:
- Bolt circle diameter
- Stud diameter and length
- Axle shaft diameter
- Axle flange-to-flange dimensions
Compare your measurements against the Timken SP500300 product specifications to ensure compatibility.
Test Fit Before Install
Do a test fit of the new bearing assembly before fully installing. Slide the Timken unit onto the axle flange by hand without torqueing anything down. Check that the bolt holes line up and the unit seats flush against the flange surface. If it does not fit cleanly, double check you have the proper part number.
Taking the time to verify proper fitment ensures a smooth install and maximizes the performance and longevity of your new Timken wheel hub assembly.
How to extend the life of the Timken SP500300 axle bearing and hub assembly?
The Timken SP500300 is a heavy duty wheel bearing and hub assembly designed for optimal life and performance. Here are some tips to help extend the lifespan of this component:
Proper Installation
Follow the manufacturer installation instructions precisely. Torque all fasteners to the specified values. This ensures the unit is properly preloaded and minimizes stress on the bearings.
High Quality Grease
Pack the Timken SP500300 with high temperature, lithium complex wheel bearing grease. This provides excellent lubrication protection. Re-grease at every brake service interval or 12,000 miles.
Avoid Contamination
Be extremely clean during installation. Any dirt or debris can contaminate the grease and cause premature wear. Thoroughly clean all mating surfaces and use new seals.
Proper Wheel Alignment
Incorrect wheel alignment applies extra load on the wheel bearings. Have your alignment checked annually and anytime you notice uneven tire wear.
Watch for Leaks
Inspect the seals around the bearing assembly when changing oil. Detecting small leaks early can prevent hub assembly damage.
With meticulous installation, routine maintenance, and contamination prevention, you can expect up to 100,000 miles of reliable service from the Timken SP500300 axle and hub assembly.
How to maintain peak performance of your vehicle with the Timken SP500300?
The Timken SP500300 bearing and hub assembly is engineered to provide ultimate performance. Here are tips to help maintain peak operation of your vehicle:
Regular Inspections
Visually inspect the wheel ends when changing oil. Look for any signs of leaking grease or loose/damaged components. Address any issues immediately to prevent bigger problems.
Proper Torque
Ensure all fasteners and mounting hardware are torqued to the vehicle manufacturer's specifications. This prevents looseness that causes premature wear.
Quality Grease
Use only high temperature, heavy duty wheel bearing grease. Grease designed specifically for wheel bearings provides superior lubrication and cooling.
Axle Alignment
Misaligned axles place extra stress on wheel bearings that lead to early failure. Have your axle alignment inspected annually and adjusted as needed.
Balanced Wheels
Wheels that are out of balance create damaging vibrations. Have your wheels balanced with each new set of tires to reduce wear on bearings.
Smooth Braking
Aggressive braking can overload the wheel hub. Drive smoothly without excessive heavy braking to ensure reliable bearing operation.
With diligent maintenance and preventing damage from vibration, misalignment, and overload, you can enjoy maximum performance from the Timken SP500300.
