We do not have any hub with that specific number, but what you may need is the the Dexter Trailer Idler Hub Assembly for 2,000-lb Axles - 4 on 4 - L44649 Bearings # 8-91-05UC1.

This doesn't have the "4" at the beginning, but will work so long as your hub has a 4 on 4" bolt pattern, uses inner and outer bearing L44649 (1.063" inner diameter) and grease seal 10-9 (1.500" inner diameter). It does come with the bearings, races and seal.

Otherwise, to determine the correct replacement hub you will need to know what bearings your current hub has. You will need to take apart your current hub assembly and look at the bearings themselves; wipe away the grease and you should be able to see the part number stamped directly on them.

If you are unable to find them, you need to use digital caliper and measure your spindle to the thousandths of an inch where the bearings and grease seal ride. You can use the photo I've attached to see exactly where you need to measure. Additionally, you need to know your hub's wheel bolt pattern; if you do not know what it is I have added a help article which details how you can find it.

I have also added a link below to our entire selection of hubs for you to come back to if # 8-91-05UC1 is not correct for you.
