Buying Guide
Choosing the right wheel bearing grease for your trailer involves considering a few key factors. Here’s a quick guide to help you make the best decision:
- Type of Grease: Lithium-based greases are common and suitable for general use. Synthetic greases offer superior performance in extreme temperatures and heavy-duty applications. Marine greases are specifically formulated for water resistance and corrosion protection.
- NLGI Grade: NLGI (National Lubricating Grease Institute) grades indicate the consistency of the grease. An NLGI grade of 2 is common for wheel bearings, providing a good balance between pumpability and staying power.
- Water Resistance: If you have a boat trailer or frequently encounter wet conditions, choose a marine grease with excellent water resistance.
- Temperature Range: Consider the operating temperatures your trailer will experience. Synthetic greases typically offer a wider temperature range than conventional greases.
- Load Capacity: If you frequently haul heavy loads, opt for a grease with good extreme pressure (EP) properties.
- Compatibility: If you’re replacing existing grease, check for compatibility. Mixing incompatible greases can lead to performance issues. When in doubt, clean out the old grease thoroughly before applying the new grease.
FAQs
Q: How often should I grease my trailer wheel bearings?
A: It depends on usage, but generally, every 12 months or 12,000 miles is a good starting point. Boat trailers may require more frequent greasing, especially after submersion in water.
Q: Can I mix different types of grease?
A: It’s generally not recommended, as incompatible greases can react and reduce lubrication effectiveness. If possible, use the same type of grease or completely clean out the old grease before applying a new type.
Q: What is the difference between lithium and synthetic grease?
A: Lithium grease is a common, general-purpose grease. Synthetic grease offers superior performance in extreme temperatures, provides better lubrication, and lasts longer.
Q: Do I need special tools to grease my trailer wheel bearings?
A: A grease gun is essential for applying grease to the bearings. Some trailers have grease fittings (zerks) that allow for easy greasing, while others may require removing the wheel and hub for access.
Q: What happens if I don’t grease my trailer wheel bearings?
A: Neglecting to grease your trailer wheel bearings can lead to excessive wear, overheating, and eventually, bearing failure. This can result in costly repairs and potentially dangerous breakdowns.
Conclusion
Choosing the right wheel bearing grease is a small investment that can save you big headaches down the road. Whether you opt for the robust protection of Lucas Oil Red ‘N’ Tacky, the all-around reliability of Valvoline, or the specialized water resistance of Mystik Marine Grease, keeping your trailer’s wheel bearings properly lubricated is essential for safe and reliable hauling. Regular maintenance and the right grease will keep your trailer rolling smoothly for years to come.
