If both the inner and outer bearings are L44643 then you have a BT8 spindle. You can use # R104BT8, # TRU97FR, or # TRU59FR. All three of these spindles are rated for 1,000 pounds by themselves so they would be on a 2,000 pound axle. I have linked videos for all 3 spindles for you.

Please note that installation of a spindle is a precision job that requires someone with experience in welding on spindles. If the spindle is welded on a little off then it can cause tire wear, suspension, and tracking problems with the trailer.
