4. Installation Guidelines
Installation of a drive shaft bearing requires specialized tools and mechanical expertise. It is highly recommended that installation be performed by a qualified service technician. Improper installation can lead to premature bearing failure, damage to the drive shaft, and potential safety hazards.
4.1. Safety Precautions
- Always wear appropriate personal protective equipment (PPE), including safety glasses and gloves.
- Ensure the vehicle is securely supported on a stable surface before beginning work.
- Disconnect the battery to prevent accidental starting or electrical shorts.
- Refer to your vehicle's specific service manual for detailed disassembly and reassembly procedures.
4.2. General Installation Steps (Consult Service Manual for Specifics)
- Preparation: Clean the work area and gather all necessary tools and replacement parts.
- Disassembly: Carefully remove components obstructing access to the drive shaft bearing. This may include track, suspension, and other drive train parts.
- Bearing Removal: Use appropriate bearing pullers or presses to remove the old bearing from the drive shaft or housing. Avoid damaging the shaft or housing.
- Inspection: Inspect the drive shaft, housing, and surrounding components for wear, damage, or corrosion. Replace any damaged parts.
- New Bearing Installation:
- Ensure the new bearing is clean and free of debris.
- Apply a thin layer of compatible grease (as specified in Section 5.1) to the bearing surfaces if not pre-lubricated.
- Using a bearing press or a suitable driver, carefully press the new bearing into its position. Ensure it is seated squarely and fully. Do not hammer directly on the bearing races.
- Reassembly: Reinstall all removed components in reverse order of disassembly, ensuring all fasteners are tightened to the manufacturer's specified torque values.
- Final Check: Rotate the drive shaft by hand to ensure smooth movement and no binding.

5. Maintenance
Proper maintenance is crucial for extending the life of your drive shaft bearing and ensuring reliable vehicle operation. Regular inspection and lubrication are key.
5.1. Lubrication
This bearing type is typically pre-lubricated and sealed for life. However, if the bearing features a grease fitting or if the seals are compromised, it may require periodic lubrication. The compatible lubricant for this bearing is Grease. Always use a high-quality, manufacturer-recommended grease suitable for automotive or snowmobile applications and extreme temperatures.
5.2. Inspection
Periodically inspect the drive shaft bearing for signs of wear or damage, especially during routine vehicle service. Look for:
- Excessive Play: Check for any noticeable looseness or play in the drive shaft.
- Unusual Noises: Listen for grinding, humming, or squealing sounds coming from the drive shaft area.
- Vibration: Feel for unusual vibrations that may indicate bearing wear.
- Seal Integrity: Inspect the bearing seals for cracks, tears, or signs of grease leakage. Damaged seals can allow contaminants to enter and cause premature failure.
- Corrosion: Check for rust or corrosion on the bearing housing or exposed surfaces.
If any of these signs are present, the bearing should be inspected by a qualified technician and replaced if necessary.

6. Troubleshooting
If you experience issues related to the drive shaft, the bearing may be a contributing factor. Below are common symptoms and potential causes:
| Symptom | Possible Cause | Action |
|---|---|---|
| Grinding or Humming Noise | Worn or damaged bearing races/balls, lack of lubrication, contamination. | Inspect bearing for wear. Replace if necessary. Ensure proper lubrication. |
| Excessive Vibration | Bearing wear, improper installation, unbalanced drive shaft. | Check bearing for play. Verify correct installation. Inspect drive shaft for balance. |
| Drive Shaft Binding or Sticking | Seized bearing, foreign object interference, severe misalignment. | Disassemble and inspect the drive shaft assembly. Replace bearing if seized. |
| Grease Leakage from Bearing | Damaged or deteriorated bearing seals. | Replace the bearing as seals are typically integral to the unit. |
For persistent issues, consult a certified Arctic Cat service center or a qualified mechanic.
