Buying Trailer Hub Caps
It's a good idea to check the hubs on your trailer at least once a year. If you do, you'll have one less thing to worry about when you're reassembling the wheels. While you're at it, you should also make sure to replace the dust cap. This is a small item that costs between four and eight bucks for a pair.
A dust cap is an easy way to keep dust and dirt off of your wheel nuts. The best part is that they don't require much effort. Using a hammer and wood, you can pry the cap off without having to raise the wheel and jack the trailer. In fact, you can do it right on the ground with just a flat edge screw driver. You can then use a hammer to unscrew the castle nut that secures the hub assembly to the axle.
There's a good chance you've already purchased a wheel cap for your trailer. However, the dust cap is only one of many components to consider. Other parts you'll need include grease, a grease lubricant, seals and a cotter key. Once you have all your parts, you'll have a much easier time replacing your wheels. You may need to check out

One of the most important parts of the wheel hub is the bearing. These cylindrical pieces are filled with grease to reduce friction during the wheel's spin. Unfortunately, if you're not careful, you could damage the bearings or worse yet, remove the hub altogether. To avoid this fate, it's wise to install the aforementioned dust cap on a dry day. Keep in mind, however, that dust is a component that can easily become damaged over time. Also, if you have a solid rotor disc brake on your trailer, the oil-filled version is probably not the best option.
On the other hand, if your trailer has a non-oil laden hub, a grease-filled model isn't a bad idea. It should be noted, however, that oil-filled models can be prone to contamination if your trailer sits in a garage for an extended period of time. To learn more, click here:
