Correct Replacement Hub/Drum for Roadmaster Tow Dolly with Electric Brakes RM3477

Question:

My passenger side wheel is loos at the bearing and the bearing grease cap is missing. What parts do I likely need to repair this? 1. How do I find the grease cap 21-3-AL-100? 2. How do I order the 4755 cotter pin? 3. 4754 Spindle Castle nut? 4. 4753 Spindle Washer? 5. What are races? Do I need these if so, what is the order number? 6. Hub Assembly 94545? Do I need this? I dony think so? 7. Anything else for correcting the wobbly wheel assembly?

Expert Reply:

The correct replacement hub/drum for the Roadmaster Tow Dolly with Electric Brakes (RM3477) part # RM-2050-1 is the Dexter Trailer Hub and Drum Assembly part # DX68XR. This is a complete kit and what I recommend using to get back up and running.

The retainer or cotter pin likely came out causing the castle nut to back off and that is what caused the hub to become loose. There could have been damage to the hub or bearings and races which is why I recommend a full replacement.
