Product Overview
The Timken 33013 Wheel Bearing is a critical component designed for automotive and heavy-duty vehicle applications. Manufactured from durable alloy steel, this bearing ensures reliable performance and longevity in demanding environments. It is engineered to facilitate smooth rotation of wheels, reducing friction and supporting radial and axial loads.

Safety Information
Always prioritize safety when handling and installing automotive components. Failure to follow proper safety procedures can result in injury or damage to the vehicle.
- Wear appropriate personal protective equipment (PPE), including safety glasses and gloves.
- Ensure the vehicle is securely supported on jack stands before beginning any work.
- Refer to the vehicle manufacturer's service manual for specific torque specifications and procedures.
- Keep work area clean and well-lit.
- Do not reuse damaged or worn components.
Setup and Installation
Proper installation is crucial for the longevity and performance of the Timken 33013 Wheel Bearing. This section provides general guidelines; always consult your vehicle's specific service manual for detailed instructions.
Required Tools and Materials:
- Socket set and wrenches
- Torque wrench
- Bearing press or appropriate installation tools
- High-quality wheel bearing grease (compatible lubricant: Grease)
- Clean rags
- Brake cleaner (optional)
Installation Steps:
- Preparation: Safely lift and support the vehicle. Remove the wheel and brake components to access the hub assembly.
- Old Bearing Removal: Carefully remove the old wheel bearing components. This may involve using a puller or press, depending on the vehicle design. Clean the hub and spindle thoroughly, removing any old grease or debris.
- New Bearing Preparation: Apply a generous amount of compatible wheel bearing grease to the new Timken 33013 bearing. Ensure all roller elements and raceways are adequately lubricated.
- Installation: Using a bearing press or appropriate installation tools, carefully press the new bearing into the hub or onto the spindle. Ensure it is seated squarely and fully. Never use a hammer directly on the bearing components as this can cause damage.
- Assembly: Reassemble the hub, brake components, and wheel according to the vehicle manufacturer's specifications.
- Torque Specifications: Tighten all fasteners to the vehicle manufacturer's specified torque values using a torque wrench. This is critical for proper bearing preload and safety.
- Final Check: Lower the vehicle and perform a final check of the wheel for proper rotation and absence of play.
Operating Considerations
Once installed, the Timken 33013 Wheel Bearing operates as an integral part of your vehicle's wheel assembly. While it requires no direct "operation" by the user, understanding its function and proper break-in is important.
- Initial Drive: After installation, drive the vehicle cautiously for the first few miles. Listen for any unusual noises or vibrations.
- Load Capacity: The bearing is designed to handle specific loads. Do not exceed the vehicle's gross vehicle weight rating (GVWR) or gross axle weight rating (GAWR) as this can prematurely wear the bearing.
- Environmental Factors: Exposure to excessive water, dirt, or corrosive materials can reduce bearing life. Ensure protective seals are intact and functioning correctly.
Maintenance
Regular inspection and proper lubrication are key to maximizing the lifespan of your Timken 33013 Wheel Bearing.
Inspection Schedule:
- Inspect wheel bearings during routine tire rotations or brake service.
- Check for excessive play by grasping the wheel at the 12 and 6 o'clock positions and attempting to rock it. Any significant movement may indicate bearing wear.
- Listen for unusual noises (e.g., humming, grinding, roaring) that change with vehicle speed or turning.
Lubrication:
The Timken 33013 is designed to be lubricated with grease. For optimal performance, use a high-quality, compatible wheel bearing grease. Follow your vehicle manufacturer's recommendations for lubrication intervals and type of grease.
- If the bearing is serviceable (not a sealed unit), repack with fresh grease at recommended intervals, typically during brake service or every 30,000-50,000 miles, or as specified by your vehicle manufacturer.
- Ensure all old grease is removed and new grease is thoroughly worked into the bearing rollers and cage.
Troubleshooting
Common issues related to wheel bearings and potential causes:
| Symptom | Possible Cause | Solution |
|---|---|---|
| Humming, grinding, or roaring noise from wheel | Worn or damaged bearing; lack of lubrication | Inspect and replace bearing if necessary; ensure proper lubrication. |
| Excessive wheel play (wobble) | Loose or worn bearing; improper installation | Check bearing preload and torque; replace bearing if worn. |
| Vibration felt through steering wheel or floorboard | Damaged bearing; unbalanced wheel; other suspension issues | Inspect bearing for damage; check wheel balance and alignment. |
| ABS light illuminated (if applicable) | Damaged ABS sensor or tone ring (often integrated with bearing) | Scan for diagnostic trouble codes; inspect sensor and tone ring. |
If you experience any of these symptoms, it is recommended to have the vehicle inspected by a qualified mechanic.
