Trailer Hub with 8 Lug Bolt Pattern to Replace Hub with LM67048 and 25580 Bearings

Question

Question:

I have an old dexter style axle trailer that has a 4 wide bolt wheel. I believe the axles are 5500lb. Im looking to replace the hub and drum assemblies with an 8 lug style. The bearings are LM67048 outer and 25580 inner. I need hub/drum assemblies with bearings and seals. Could you tell me what the part number would be or let me know what other information you need please? Thanks so much.

The Dexter Trailer Hub part # 42866UC3 would fit on your current spindle and has the 8 lug bolt pattern you are looking for. This comes with bearings and seals. The bearing numbers aren't an exact match but they fit the same spindle dimensions.

Answer 11

Your math is correct in your trailer weight load example. If a fully-loaded tandem axle trailer weighs 4000-lbs then each of the 4 tires will bear 1/4th of that load, or 1000-lbs. In this case a tire rated for 1300-lbs would provide a good safety…
