Please Note: Some axles rated at 2,000 lbs require a different seal and bearings. Be sure that the bearings in the hub being replaced have L44649 stamped on them. If the bearings have L44643 stamped on them, use # 8-258BTUC1 trailer hub.
Note: Most trailer tires that are smaller than 15" and have 5 bolts, have a 5 on 4-1/2" bolt pattern.
How to Measure Bolt Pattern
The first number in the bolt pattern is the number of bolt holes. The second number is the diameter of the circle the holes sit on. To determine the diameter on wheels with an even number of bolt holes, measure center-to-center on bolt holes directly across from each other on the circle (Example: 8 on 6-1/2 would mean 8 bolt holes with 6-1/2" center-to-center diameter). When the number of bolt holes is odd, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from it on the circle (Example: 5 on 4-1/2 would mean 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolts).
AND / OR
The distance between the center of one bolt hole on the wheel to the center of the bolt hole right next to it will also help determine the bolt pattern.
- If D = 2-5/8" then the bolt pattern is a 5 on 4-1/2
- If D = 2-3/4" then the bolt pattern is a 5 on 4-3/4
- If D = 3" then the bolt pattern is a 5 on 5
- If D = 3-1/4" then the bolt pattern is a 5 on 5-1/2

- Which Hub fits an Outer Bearing L44649 and Outer Race L44610
- Trailer hubs have two bearings, one is referred to as the inner bearing, closer to the trailer. The outer bearing is the one furthest from the trailer. If we have both of these bearing numbers we can identify which spindle or hub is needed.
So far you have L44649 as your outer bearing and L44610 as your outer race. We carry 8 hubs that use outer bearing L44649. Your inner bearing should either be another L44649 or an L68149. Once you provide us with the second bearing number, I can provide yo

- Hub and Drum Assembly Recommendation
- For an idler hub I would recommend that you get a Trailer Hub Assembly, part # 84545BX. This hub has the same inner/outer bearings and seal size as your current hub so it would work well for you.
For a brake hub I would recommend that you get a Trailer Hub & Drum Assembly, part # 84557UC3.
Both these drum assemblies use the same bearing and seal size that came off of your old hub, so this will work on your spindle perfectly.

- Is There a Hub Available with L44649 an LM11749 Bearings
- It sounds like you might have an older agricultural hub and spindle on your trailer based on the LM11749 bearing that you referenced as I can not find any information on hubs with that bearing number.
I am going to send you a separate email that is going to have a picture of a spindle with measurements on it. If you could use a dial caliper and give me those measurements I would be able to know for sure if there is a hub that I could recommend for you.

- Bearing Numbers not Readable
- For your inner bearings and grease seals, if the reference number cannot be located, having an accurate measurement of both the inner and outer diameter of the bearing and seal will be very helpful in finding a replacement. A digital caliper is called for, as a ruler or tape measure will not give an accurate enough measurement.
If you can reply with the measurements, I will find replacements for you.

- How to Determine the Size of a Trailer Hub Assembly for Replacement
- To determine the size of the hub assembly you need to purchase you have to determine which bearings are in the old assembly.
