How often should you re-pack grease hubs? I run oil hubs on all my trailers, but I fitted new K-Hitch axles on my converter dolly and they have grease hubs. A Google search didn’t come up with much relevant info.

I pull them down and inspect and repack along with new seal at every brake job. I believe it is a recommendation of hub mfg’s
Ozdriver and Pamela1990 Thank this. -
Problem is my brakes last forever. The dolly has done 330,000 kms (205,000 miles) and the brakes are barely worn. I just took a little play out of the bearings yesterday and I was thinking it’s about time I re-packed the bearings. About one third of the mileage is when there is no load on it when I tow it behind a trailer.

A large fleet I worked for did them at 5 years. Hendrickson standard hub repack and seal schedule is 2 years or 300,000 km. Preset hub schedule is 5 years or 800,00 km. -
Welcome back….
How much dirt and flooded areas do you deal with……? I would guess that changes the service interval…..
I’m an oil hub guy too….Ozdriver and Diesel Dave Thank this. -
With 2 trailers at 79 tonnes about the same fuel mileage as a modern truck as long as you drive it correctly.BoxCarKidd Thanks this. -
Yes, oil hubs are best imho, as long as bearing pre-loads are correct and you use properly installed quality seals. -
Oxbow and Diesel Dave Thank this.
