Hey Brian, the Grease Seals 10-36 # RG06-070 are most commonly found on 8k trailer axles so you could potentially use these, but I'd recommend measuring the inner and outer diameter of your current seals to make sure they fit.

If you measure 2 1/4 (2.25") for the inner and 3 3/4" (3.376") for the outer, these will work for you. If not, feel free to come back and let me know and we'll see what we have for you.

If you have any other questions in the meantime, please feel free to let me know!

The #84 spindle is just a common way to identify the spindle dimensions typically used for 3,500 lb axles. So instead of listing out the parts, people can just say they have #84 spindles and it's easier to know what fits it. The CE Smith Trailer…

The Demco Hydraulic Trailer Brake Actuator part #DM72VR should be a direct replacement for the Atwood 61101 Brake Actuator that you have now. This newest updated it rated at 7K instead of 6K. This is a bolt on option that mounts on 3" centers.…

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…

That's a very good question, we tend to be extra cautious and say to use 10 gauge wire because that would be more than enough. When you get into longer trailers that will end up using a lot of wire the heavier gauge wire becomes more necessary.…
