This uses a sealed pressurized oil chamber to protect your bearings, which means no routine maintenance. Just install it and enjoy the peace of mind of having this installed.

So this is designed specifically for your 7,000 pound Trailer Buddy axles with 2.717 inch hubs. So this is a heavy duty solution for those heavy duty trailers.

And this kit includes everything that you see here. You are going to get these two Trailer Buddy Vault assemblies. Lemme see if I can set that there without it rolling away there. And then you're also going to get two O-rings, as you can see there. And there, you're gonna get two vault lube tubes, one vault installation tool, one grease fitting, and then a small tube of thread locker.

Now because this system is completely sealed, water and dirt, it's gonna stay out, which is gonna help prevent wear and it's gonna keep you out of the shop. So overall, this is really a hassle-free way to keep your trailer rolling smoothly for the long haul. Now if you happen to have any other questions, whether it's about this kit or anything else that we carry here at Etrailer, don't hesitate to reach out because ultimately we wanna make sure that you're getting exactly what you need.

  • Dexter Vault Hub Service Kit Replacement Kits
    Hey Daniel, I'd be happy to help! We actually have replacement kits for the Vault style hubs, but it really depends on what you're needing to fix. Here are the kits listed out according to axle capacity: - 2.5K-3.5K # DX52UR - 4.2K-5.2K # DX23ER - 6K # DX83ER - 7K # DX73ER Do these kits seem to have what you're needing, or are you needing something else that's not included in the kits?

  • Dexter Vault Hybrid Lubrication System for Boat Trailer Axle
    Hey Chad, we do have Dexter Vault kits like it sounds like you are looking for but it comes down to what capacity axle you have to determine which kit you need. # DX52UR is for 2500 to 3500 lb axles # DX23ER is for 4200 to 5200 lb axles # DX83ER is for 6k axles # DX73ER is for 7k axles. Since you mentioned 1.98 inch diameter its very likely what you need is the part # DX52UR for 3,500 lb axles.
