Expert Reply:

It looks like you have the Dexter Trailer Hub and Drum Assembly part # 8-174-5UC3 which is for old 6,000 lb to 7,000 lb axles that have the 5 on 5" bolt pattern. If that is the case then you can use the Trailer Idler Hub Assembly part # AKIHUB-655-6-K and the 10-10 Grease or Oil Double-Lip Seals part # RG06-090 to switch to a more common 6 on 5-1/2" bolt pattern.

In order to confirm the above, you simply need to find the axle tag and look for the weight capacity and or serial number or if the axle tag is not present you can pull the old hubs off and measure the spindle or bearings to compare to the above.

I have attached a selection of our wheels and tires for you as well below with the above bolt pattern.
