Using the grease zerk to lube the bearings can be risky to your brakes. Some have success, some don't .....Make sure you follow the axle manufacturers' exact instructions for best results.....
Bearing service intervals are really dependent on operating conditions and mileage, plus ambient conditions during periods of storage.
One thing that most forget about is brake inspection and maintenance -this needs to be done regularly too on electric brakes.
All that being said: The Dexter Axle Specs
I use Lucas Red-n-Tacky as it surpasses the above specs plus the Alko dropping point spec. The Alko axle grease specs are similar but ask for a dropping point temperature of 440F. EP and corrosion protection is real important for units that sit then get used for high speed operation. Corrosion protection is real important for climates with the potential for condensation when the seasons change.
