Can Bearing Protectors be Added to an EZ Lube Trailer Axle with Grease Zerk Fittings


My utility trailer has a 3500 EZ Lube axle with a frozen zerk fitting. Instead of simply replacing the fitting, is there an advantage to installing bearing protectors like the ones I have on my boat trailer? They do an excellent job there, but would it be overkill for a land-based trailer?


Expert Reply:

Because your axle has the zerk fittings at the ends of the spindles, a bearing protector like a Bearing Buddy physically will not fit. You would either need to remove the zerk to use a bearing protector or replace the zerk fitting an continue using it. Zerk fittings are not always easily replaced if they have been pressed in so removing it may be the only option.

Bearing protectors work well for boat or regular trailers and I would not say it is overkill for a strictly land trailer. To get you the correct size bearing protector I would need to know the bearing numbers on the trailer or the measurement of the hub bore where the bearing protector goes. The measurement needs to be as precise as possible so using digital calipers is the best way to get an accurate measurement.

I have included a link to the bearing protectors we carry.
