Has anyone changed a wheel bearing from the "you pack" to a zerk fitting? I do not want the simple dust cover with the zerk - I would like to change the wheel bearing over to the zerk that is part of the bearing assembly.
Anyone?

If you are want to have the "E-Z Lube" system made by Dexter, you will have to replace your axles to ones that have "E-Z Lube" spindles mounted on them. That is not a cheap mod because you are looking at, at least a $1500 cost. That, to me, would not be a modification worth the money.

I have the E-Z Lube system and it's ok, but I still take off the wheels to inspect the bearings and repack them by hand.

I talked with Dexter a few years ago and they told me the E-Z Lube was never intended to be the primary method to pack the wheel bearings. Rather, the E-Z Lube system was designed for boat trailers so the bearing housing could be charged with grease to reduce the infiltration of water into the bearings. According to Dexter the E-Z Lube does not adequately pack the bearings to be used as the primary way to pack the bearings.

Thanks for all the great feedback guys!! I have decided, based on your sage input, to go the "pack my own" route. Kind of like the "roll yer own".....
Great forum - thanks again guys!

That is not what their literature says: http://dexteraxle.com/i/u/6149609/f/...-Lube_7-11.pdf

I would be careful with EZ lube hubs or any device that allows you to push massive amounts of lubrication into the bearing hub. Too much grease will blow the seals on your drums and allow grease to infiltrate your brake shoes. Grease on brake shoes or brake drums is bad. There is a proper way to use the ez lube hubs and that is to take the rubber cap off, jack up the axle so you can spin the wheel as you pump a few strokes of grease in the cavity. Wipe off all the excess grease, actually I try to remove any excessgrease near the opening before putting the rubber caps back on. This will prevent pressure build up from pushing the rubber caps off while you are under way. This is the proceedure I use on my boat trailer. On my 5th wheel I simply repack by hand every other season and have never had problems with this schedule. How often do you pack the wheel bearings on your truck??? That's right, practically never or everytime you replace brakes. Why do people think they need to continually lube the wheel bearings on their RV trailer. They don't get submerged like boat trailers.

Like Pulldog said do you repack the truck wheel bearings? This subject has been beat to death. I posted on this a couple years ago. If you use a hand grease gun and pump it slow you will be alright. I have never taken a trailer bearing apart and greased it that I own. My company has trailers that are pulled everyday all year and have the same setup. I work on them and we pump grease to them. The wheel bearing problem is the bearing gets loose and that is the trouble not the greasing. Same for the grease seal. Yes you need to jack them up and see if they are loose if so tighten them and go on. Hope this helps.
