I couldn't find any information on the LM11710 race that you have and the L44610 is the race for two bearings, L44643 and L44649.

In order to pick out the correct hub assembly for a trailer you are going to need know a few key pieces of information. The first thing you will need to know is the bolt pattern of your hubs. This is so you get a hub that is compatible with your wheels. I attached an FAQ article on determining bolt pattern for you to check out.

Next thing you will need to know is what spindle you have on your trailer. In order to do that you can either get the inner and outer bearing numbers from a hub or use a dial caliper to get exact measurements of the spindle. The measurements needed are the parts of the spindle where the bearings ride.

If you get back to me with that information I will help you pick out the right hub assemblies. Or, you can follow the link I attached that will take you to the page that has all of our replacement hubs.

You would want to first select the bolt pattern that you have, next select the inner bearing you have, followed by selecting your outer bearing, and then all the correct hubs will be listed.

A BT8 spindle would have a diameter of .99 of an inch where the bearings would both install and would have a diameter of 1.24 where the great seal would ride. That would require a hub part #AKIHUB-440-2-1K for an idler hub. A BTR spindle would have…

From the numbers you provided it sounds like you need replacement grease seals. In my research, the grease seals I found with the GS-1719DL number have a 1.72 inside diameter and 2.565 outside diameter. The replacement double lip grease seals you…

To determine the size of the brake assemblies you need you have to measure the depth and width of the hub drum on the axle like what you see in the picture I attached. The most common size is 2-1/4 inch wide like the #T4071600-500 that you…

Hey Dave, what you gave me is enough info to get you replacement bearings. The grease seal 471750 matches the part #TMK48ZR. For a Timken replacement for the L44610 part number you'd need #TMK63VR. Then for a bearing for the L44649 you'd want…

Answer 8

The BTR and BT8 denotations refer to the spindle, not the trailer hub. The difference between a BTR and BT8 spindle is that the BTR spindle uses a 1.063" diameter L44649 bearing and the BT8 spindle uses a 0.99" diameter L44643 bearing. In…

We do have a compatible grease seal for your 168255TC oil seal, however, we do not carry rubber coated seals in this size. The 168255TC oil seal was designed to work with oil bath hubs on a 3,500 lb axle. For the most part, axle manufacturers have…

The #99 trailer spindle is typically found on 9,000 lb and 10,000 lb axles. This is not a spindle that we carry at this time, but I did find some of the measurements. I have attached a diagram showing the dimensions of a #99 spindle for you to check…
