Leaking Hub

[PoPo Cliff]

Need help. I have noticed one of the hubs leaking grease. All 4 hubs have grease from factory, whatever brand it is. I have not added any grease. I have towed camper 850 miles since new. Could it be a bad seal on the cap? Could it be grease not thick enough? Is this something I need to be concerned about? Any ideas, solutions would be appreciated.

I put a bead of black RTV around the lip of the cap. No more greasy wheels.
Service manager said they just leak sometimes.

Thank you. I'll give that a try.

If the grease is breaking down enough to leak out like yours I'd recommend pulling the wheel for inspection and a manual cleaning & a hand repack using a high quality grease. The grease breaking down could mean it's been hot or it seperated and now isn't lubing the bearings. From the factory it may only have a wipe of grease.

I pulled mine off and the grease was completely fine. Checked the hubs while traveling, not getting too hot. They just leaked.
I chalk it up to the mating surface between the two not machined smooth enough.

Mine did the same thing took it back to the dealer 3 times. Finally convinced them to replace the grease seals. They finally agreed! No more leaks.
