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.
