I have a friend with a 2018 Ranger trailer that has both hubs on the rear axle leaking. I have a Triton trailer, same year with spring axles and I have rebuilt 3 of my Vault hubs so I know how to do it on my trailer. Is a torsion axle the same, you just pull the caliper and then remove the hub? Can he pull the caliper and take the hub somewhere to be rebuilt? I don’t think he’s comfortable doing it himself. Thanks
