Hi Danny,
Evangeline asked if I could get you helped out as she is climbing around the roof of an RV at the moment and couldn't get to a computer, so here I am. Let's get into it.
Since you have a 3,500 pound axle with Dexter's Vault system, you are going to need our # BK2-100 bearing kit. This is specifically comprised of bearings, races, a tang washer, and a cotter pin, and a seal for your size axle/spindle. However, the Vault System does throw a small wrench in the preverbal spokes.
The seal that comes included ( # 58846 ) is for a standard grease style set up, so it isn't the best option for you. The Timken # TMK58ZR will work with grease or oil, so I would also grab one (or however many you need to replace). The Vault System is kind of odd and basically turns from grease to oil as it heats up so the Timken will do a better job of keeping everything contained. The # 58846 seals that come in the kit can be kept in the case of an emergency as they will technically work, but the Timken ones are better to have on for every day use.
If you are also needing this grease stuff, we have it in 14 oz. tubes with part # DX94TR.
Let me know if you need anything else or have any other questions : )
