Wheel bearings play a critical role in the safe operation of camper trailers, allowing wheels to spin freely and bear the load of the vehicle. Too much or too little play in the bearings can lead to heat, premature damage, and even spindle failure. The ideal amount of play in camper wheel bearings is a maximum of 1/16 of movement when pushing and pulling the entire trailer tire. Some sources suggest a maximum play of 1/8 for lighter trailers, while others recommend no play at all. Regular maintenance, including repacking with grease every two years, is essential to ensure the longevity of camper wheel bearings.

What You'll Learn
Wheel bearings should have no more than 1/16 of play
Wheel bearings play a critical role in allowing your wheels to spin. If they are too tight, the wheels won't spin, and if they are too loose, the wheels may fall off. Therefore, it is essential to ensure that your trailer wheel bearings have the correct amount of play.
The ideal amount of play in trailer wheel bearings is about 1/16" of movement side to side. This means that you should be able to move the entire trailer tire by up to 1/16" with your hands. Anything more than this can cause excess heat and added wear and tear on your bearings, axle, spindle, and trailer. This is especially true if your trailer is loaded with weight and travelling at high speeds.
To check for the correct amount of play in your wheel bearings, first, ensure there is no load on the trailer. You can do this by jacking up your trailer and using wheel chocks on the opposite trailer tire. Once the trailer tire is raised enough to spin freely, grab each side of the tire at the 3 and 9 o'clock positions and push one hand in while pushing the other hand out. You should feel the play between the bearing and the spindle. While a maximum of 1/16" of play is recommended for safety, some people suggest a maximum of 1/8" of play for lighter trailers with lower loads.
If you find that your trailer wheel bearings have too much play, you can easily adjust them by following these steps:
- Remove the grease cap and cotter pin.
- Loosen the castle nut to allow for more play on the bearing.
- Spin the wheel hub assembly to ensure the bearings are not bound or off-center.
- Tighten the castle nut while spinning the wheel hub assembly until it slowly stops spinning.
- Loosen the castle nut slightly so the hub spins freely again, then tighten it again.
- Set a new cotter pin in the hole without adjusting the castle nut position.

Too much play can cause heat, damage, and spindle failure
Wheel bearings are an essential part of any vehicle, including campers. They allow wheels to spin freely and support the weight of the vehicle. However, too much play in camper wheel bearings can lead to several issues, including heat generation, premature damage, and spindle failure.
Firstly, let's understand what is meant by "play" in wheel bearings. Play refers to the amount of movement or looseness in the bearings. Ideally, you want your wheel bearings to have a minimal amount of play to ensure optimal performance. If there is too much play, it can lead to adverse effects.
Now, let's delve into the potential consequences of excessive play in camper wheel bearings:
Heat Generation
Wheel bearings are designed to reduce friction and prevent the build-up of excessive heat. However, when there is too much play in the bearings, they can generate additional heat due to increased friction. This excess heat can lead to several problems, including the breakdown of bearing grease, which lubricates the bearings and prevents wear. Overheated bearings can also increase the risk of fires in the wheel well area, posing a severe safety hazard.
Premature Damage
Excessive play in camper wheel bearings can lead to premature damage and a shortened lifespan. The increased friction caused by loose bearings can result in abnormal wear and tear on the bearings, compromising their integrity. This can lead to unexpected failures, leaving you stranded on the road.
Spindle Failure
The spindle is the central shaft that the wheel bearings rotate around. When there is too much play in the bearings, it can place additional stress on the spindle. The excessive movement can cause the spindle to fail prematurely, resulting in a loss of support for the wheel and potential wheel detachment. This can be extremely dangerous, especially at high speeds.
To avoid these issues, it is crucial to maintain proper wheel bearing play. Regular inspections and maintenance are essential to ensure the bearings are in good condition and adjusted correctly. By keeping the play within the recommended tolerances, you can help prevent heat generation, reduce the risk of premature damage, and ensure the safety and reliability of your camper's wheel bearings.
In summary, too much play in camper wheel bearings can lead to heat generation due to increased friction. This excess heat can cause bearing grease breakdown and increase the risk of fires. Additionally, loose bearings can result in premature damage and compromise the integrity of the bearings. Finally, excessive play can place added stress on the spindle, leading to potential spindle failure and wheel detachment. Therefore, it is vital to maintain proper wheel bearing play through regular inspections and adjustments to ensure the safety and longevity of your camper's wheel bearings.

Bearings should be checked and repacked every 1-2 years
The first symptom of wheel bearing trouble is usually noise. A rumbling, growling, chirping, or cyclic noise from the vicinity of the wheels is a good indication that the bearings need to be inspected without delay. Wheel bearing noise is usually proportional to vehicle speed and does not change when accelerating, coasting, or decelerating. The noise may change when turning or become louder or even disappear at certain speeds. However, it shouldn't be confused with the clicks and pops produced by a worn or damaged outer CV joint on a FWD car.
If you notice any abnormal movements when you move the trailer wheels, this could indicate that you have loose or failing bearings. For example, if the wheel doesn't move as expected and has a bit of a wobble, this could be a sign of an issue.
To check for bearing play, you will need to ensure no load on the trailer. The best way to do that is to jack up your trailer. Once the trailer tire is raised enough to spin freely, it's free enough to check for bearing play. Grab each side of the tire (3 and 9 o'clock work) and push one hand in while pushing the other hand out. You should feel the play between the bearing and the spindle. The ideal situation is no play, and your wheel does not move at all but still spins freely.
The maximum recommended play when moving the wheel in and out is 1/16". Some recommend a maximum of 1/8" play, which is fine for a lighter trailer with not much load. However, if you have a travel trailer or a boat trailer going at high speeds, it is better to stick with the tighter tolerance of 1/16" maximum. If there is more play than that, it can cause added stress and friction to your axle, spindle, and bearings, especially when your trailer is loaded with weight and travelling at high speeds.

To check play, jack up the trailer and spin the wheel
To check the play in your camper's wheel bearings, you'll need to jack up the trailer and spin the wheel. Here's a step-by-step guide to help you through the process:
Step 1: Jack Up the Trailer
Ensure your trailer is parked on flat ground and securely parked. Use a jack to lift the trailer arm at the designated jacking point. It's important to use jack stands for added safety. If you're checking the bearings on only one side, use wheel chocks on the opposite trailer tire to prevent any accidental movement.
Step 2: Remove the Wheel
Once the trailer is safely lifted, remove the wheel. You can do this by using a lug wrench to remove the lug nuts securing the wheel to the trailer. Set the wheel aside, as you'll be performing tests on it later.
Step 3: Inspect the Wheel Hub and Spindle
With the wheel removed, you can now visually inspect the wheel hub and spindle for any signs of wear, rust, or damage. Pay close attention to the grease seals and the cap on the outside of the wheel hub. If you notice grease splatter, it could indicate a leak, contamination, or over-greasing.
Step 4: Spin the Wheel
Now, grab the wheel you removed earlier and perform a spin test. Hold the wheel at the 3 and 9 o'clock positions and push one hand in while pushing the other hand out. This will help you feel the play between the bearing and the spindle. Ideally, there should be minimal to no play, and the wheel should spin freely.
The maximum recommended play varies, with some sources suggesting 1/16" and others suggesting up to 1/8". Lighter trailers can handle a bit more play, up to 1/8", while heavier trailers or those travelling at high speeds should stick to a tighter tolerance of 1/16" or less.
Step 5: Listen for Noises
While spinning the wheel, pay close attention to any noises coming from the hub. If you hear growling, whining, grinding, or other rough noises, it could indicate that your wheel bearings are in poor condition and may need to be replaced or regreased.
Step 6: Shake Test
In addition to the spin test, perform a shake test. Gently shake the wheel and listen for any abnormal noises. Also, pay attention to how the wheel feels. It should have a slight shake but shouldn't be too loose or too tight.
Step 7: Reassemble and Adjust
If you find that your wheel bearings need adjustment, you can follow the steps outlined in the previous section on 'How to Adjust Bearing Play'. This includes removing the grease cap, cotter pin, and castle nut, spinning the wheel hub assembly, and then tightening and readjusting the castle nut to achieve the correct amount of play.
Remember, it's crucial to maintain your camper's wheel bearings properly to ensure a safe and smooth towing experience. Regularly inspect and service your wheel bearings, especially before long trips or during regular maintenance intervals.

If bearings are too tight, they can be loosened
If your camper wheel bearings are too tight, they can be loosened. Tight bearings will not allow your wheels to spin, so they will need to be loosened to avoid this issue.
To check if your wheel bearings are too tight, you can try moving the wheels on your trailer from side to side. If there is less than 1/8" of movement, or play, then your bearings are too tight. Some sources suggest that even less play, as little as 1/16", can indicate that your bearings are too tight. If your wheel bearings are too tight, they can be adjusted to have the correct amount of play.
To loosen your wheel bearings, you will first need to raise the trailer wheel off the ground. You can then follow these steps:
- Remove the grease cap.
- Remove the cotter pin by bending it with pliers and sliding it out of the hole.
- Loosen the castle nut.
- Spin the wheel hub assembly.
- Tighten the castle nut as the wheel hub assembly is spinning, just enough to slow the spinning.
- Loosen the castle nut again so that the hub spins freely.
- Tighten the castle nut again.
- Set the cotter pin in the hole without adjusting the castle nut position.
It is important to note that adjusting wheel bearings requires specific tools and knowledge. If you are unsure about how to adjust your wheel bearings, it may be best to consult a professional or a mechanic. Improperly adjusted bearings can lead to safety issues, such as wheel separation, and can cause damage to your vehicle.
Additionally, if your bearings have suddenly come loose, it may be a sign that they are failing and need to be serviced or replaced. In this case, loosening the bearings may not be the best solution, and consulting a professional is recommended.
