The last few months we have had numerous questions about changing Vault hubs to normal grease, instead of the thixotropic grease that turns to liquid when moving. Well, Dexter staff was in this week and we visited on this topic.
There is nothing necessary and we suggest hand packing the wheel bearings with red Valvoline grease and reassembling. The front seals in a Vault are tighter tolerance than Bearing Buddies and the rear seal is identical.
You just hand pack and reassemble.
