Knowing if You've Got the Right Trailer Wheel Hub

Trailer wheel hubs are an important part of making sure a trailer runs properly. Unlike the truck or car pulling the trailer, there is no central suspension that coordinates all the wheels together. This is where a trailer wheel hub comes in. Without the wheel hub to align the wheels together, you might end up conducting repairs more than traveling.

This is why making sure that you have the right wheel hub for your trailer is important. Some reasons for installing a new wheel hub may range from the old one having worn out to needing a total overhaul after an accident. The end result must always be choosing the correct wheel hub. To do this, there are a few things to consider:

• Check on the number of stud holes in the hub. They are either four or five depending on the make of your trailer.

• Check the bolt hole in the center of the hub and measure it. This is where the castle nut goes to hold the entire thing together and the correct diameter makes sure it is a snug fit. Castle nuts usually range from four to six inches, so measure carefully.

• There are inner and outer ball bearings in the hub and you need to know their sizes. Just check on their reference number.
