I have a vault hub leaking out of the front. I have watched videos and don’t feel comfortable doing the work myself. Where on the east side of Dallas can I take it to get the bearings replaced and new vault hub put on? Or should I just buy the entire assembly and just replace it? I’m new to vault hubs.

Don't fear the Vault, you can do it!

Buy new one and replace, then rebuild it as a backup

Not that hard to redo them just a little messy because of the oil in them. If you want someone to do it I'd check with McGill Trailers in Lewisville.

rockwall marine did mine excellent job no problems since

I had 2 vault covers fall off. Replaced them with bearing buddies. Had more problems than ever with those 2 tires.

I finally just bought 4 hubs/spindles from the factory and replaced all 4.

I feel much more comfortable on the road than had i repaired myself. Just depends on how much co fidence one has in their abilities. I was once pretty confident in my repairs, not so much anymore.
