Unless you are building one from the ground up, chances are your trailer came with a hub and drum assembly already installed. If not, it can seem a bit confusing selecting which one you may need.
And if you are building a trailer to certain specifications or for certain purposes – like hauling a boat – Camco Wheel & Axle is stocked full of all the brand name commercial truck and utility trailer accessories you’ll need to have a vehicle you’ll be proud of. Of course, if you need a new hub and drum, there are certain things you need to look out for.
- Find Out How Many Stud Holes Should be in the Assembly
Most hub assemblies come with four to five hole patterns within its circumference. These holes allow the studs through, joining the tire hub cap to the wheel hub. Of course, if the patterns don’t match, there is no way that the trailer tire can stay secured to the hub.
- Find Out What Type of Spindle You Have on Your Trailer
There are a few ways you can find the diameter of your bearings. You could use a digital caliper to measure the diameter of where the bearings would be riding on the spindle.
If you don’t have one handy, the next best thing you can do is to use measuring tape and wrap it around the parts of the spindle where the bearings will ride.
Perhaps the easiest options, you can scan your old hub’s bearings for a part number. This part number can then be relayed to a vendor who can then provide the accurate measurement as per the manufacturer if it isn’t printed on the bearing itself.
Keep in mind that measurements must be precise as possible for safety reasons.
