Availability of Replacement Hubs for a Harbor Freight Trailer

Question:

Will this hub fit a HF 1720lb utility trailer axle? Ive read that 1inch I.D. bearings will work for this trailer. Im having issues with one of my seals leaking, even though its been replaced several times, and like the idea of having a more standard and accessible setup. I understand that in using this hub, I may need to use a HF compatible axle seal.

Harbor Freight trailers do not typically use standard hubs or spindles. In most of the situations that we have encountered, we do not carry a hub that uses the same bearings and seal that Harbor Freight uses.

The best way to determine if we have a hub that will fit your trailer would be to find the bearing and grease seal part numbers and search for a hub that uses the same bearings and seal. I have attached a photo that shows where the part numbers are located.

If you do not have the bearings or they are too hard to see, you can also measure the bearing and seal journals on the spindle. The photo I attached also shows where to measure on a spindle. With these measurement we can determine if any of our hubs will fit. We strongly recommend using a precise measuring tool such as a digital or dial caliper because these measurement must be exact to the thousandths of an inch.
