Will Upgrading Hub Capacity Fix Leaking Grease

Question:

I have a 12k 5th wheel with 5200lbs axels. I continue to have grease leaking from my bearings. By upgrading to 7k hubs, would I gain anything. I have been using Amsoil red synthetic grease.

Hubs with a larger weight capacity will not ensure you stop leaking grease, though all new hubs may fix the issue. The reason you are leaking could be a few different things, from using a powered grease gun if you have an EZ Lube spindle to a seal not being installed flush with the hub or the hub could be somehow damaged.

I recommend taking you hubs off and inspecting it for damage while also ensuring the bearings and seal are correctly installed.
