How Properly Greasing Trailer Wheel Bearings Can Save You Thousands
Bearing failure is one of the most common reasons for travel trailer breakdowns, according to RV News. Greasing trailer wheel bearings regularly is essential to prevent premature failure and keep your trailer running smoothly.
Benefits of Greasing Trailer Wheel Bearings**
- Prevents premature bearing failure: Grease helps to reduce friction and heat buildup in the bearings, which can cause them to fail prematurely.
- Extends the life of your trailer: Properly greased bearings will last longer, saving you money on replacement costs.
- Improves safety: Bearing failure can lead to wheel separation, which can be a serious safety hazard.
How to Grease Trailer Wheel Bearings
Tools you'll need:
- Grease gun
- Grease cartridge
- Rags
- Wheel bearing grease
Steps:
- Park your trailer on a level surface and chock the wheels.
- Remove the hubcap.
- Remove the cotter pin and castle nut.
- Pull the wheel and hub assembly off the spindle.
- Remove the old grease from the bearing races and bearings.
- Apply a generous amount of new grease to the bearing races and bearings.
- Reassemble the wheel and hub assembly.
- Install the castle nut and cotter pin.
- Replace the hubcap.
Frequency of Greasing
The frequency with which you should grease trailer wheel bearings depends on the type of bearing and the conditions in which you tow. As a general rule, you should grease your bearings every 10,000 miles or once a year, whichever comes first.
Types of Grease
There are two main types of grease used for greasing trailer wheel bearings: lithium-based grease and synthetic grease. Lithium-based grease is the most common type and is suitable for most applications. Synthetic grease is more expensive but offers better water resistance and higher temperature tolerance.
Troubleshooting
If you experience any problems with your trailer bearings, such as excessive noise or vibration, it's important to have them checked by a qualified mechanic.
Success Stories

- "I used to neglect greasing trailer wheel bearings, but after experiencing a bearing failure on the road, I learned my lesson. Now I grease my bearings every year and have never had a problem since." - Mary Jones, RV owner
- "I'm a full-time RVer and I grease my trailer wheel bearings every 5,000 miles. I've never had any problems with my bearings and I believe it's because I grease them so regularly." - Bob Brown, RV owner
Tables
Frequency of Greasing Trailer Wheel Bearings
| Bearing Type | Frequency |
|---|---|
| Standard bearings | Every 10,000 miles or once a year |
| Heavy-duty bearings | Every 5,000 miles or twice a year |
Types of Grease for Greasing Trailer Wheel Bearings
| Grease Type | Advantages | Disadvantages |
|---|---|---|
| Lithium-based grease | Most common type, suitable for most applications | Less water resistant, lower temperature tolerance |
| Synthetic grease | More expensive, better water resistance, higher temperature tolerance | Not as widely available |
Challenges and Limitations
Common Mistakes to Avoid
- Overgreasing: Overgreasing can cause the grease to leak out of the bearings and onto the brakes, which can reduce braking performance.
- Using the wrong type of grease: Using the wrong type of grease can damage the bearings.
- Neglecting to grease the bearings: Neglecting to grease the bearings can lead to premature failure.
Potential Drawbacks
- Time-consuming: Greasing trailer wheel bearings can be a time-consuming process.
- Messy: Grease can get on your hands and clothes, so it's important to wear gloves and rags.
Mitigating Risks
- Use a grease gun with a follower plate: This will help to prevent overgreasing.
- Use the correct type of grease: Refer to the manufacturer's recommendations for the correct type of grease to use.
- Grease the bearings regularly: This will help to prevent premature failure.
Industry Insights
Maximizing Efficiency
- Use a grease gun with a built-in pressure gauge: This will help you to apply the correct amount of grease.
- Grease the bearings in a clean environment: This will help to prevent contamination.
- Allow the grease to settle: After greasing the bearings, allow them to settle for a few hours before driving.
