Expert Reply:
Hey Jesse. The Terran Axle Trailer Idler Hub Assembly for 5,200 to 6,000 lbs Axle - 6 on 5-1/2 item # TX43VJ is indeed compatible with the #42 Spindle for 5,200-lb to 7,000-lb Trailer Axles - 2-1/4" Diameter item # TRU57FR. Both of these parts are sold individually.
Manufacturers don't give out CAD files because they don't people making their own parts. I have attached a diagram of the #42 Spindle item # TRU57FR below.
What kind of trailer do you have?

Hey Jesse, did the hub and spindle end up fitting together the way you needed for your trailer? Your update could make it easier for the next person working on a similar axle setup.
