Greasing wheel bearings, super easy

[bingraham66]

Just finished using the ezlube hubs on our A122 to grease the wheel bearings. To my surprise it took longer to jack up each wheel then the time to spin the wheel while using the grease gun. The whole process took less than thirty minutes.

They are great but you still need to check your bearings occasionally which requires disassembly.

[bingraham66]

You do indeed but following the manual. No grease came out the rear of bearing and all is well.

Since the A122 is an A Frame and doesn't have brakes, you can see the rear seal so E-Z-Lube works well on them. You can tell if grease is blowing past the seal, unlike larger RV's with brakes where you can't see the rear seal.

Depending on state requirements, the A122 may come with brakes. My T12RB (Flagstaff version of the A122) has brakes. Just mentioning so people are aware.

[bingraham66]

Yup.. the A122 has electric brakes.

I used EZ lube on my trailer in the fall of 2018 near the end of the season. Initially all is well but that next spring the brakes were not feeling like they were working as well. I decided to pull each of the drums to check the brakes. On the last wheel I found the brakes covered with grease. The pressure from the grease gun had literally pushed the seal out of the drum allowing the grease to then enter the brake assembly. I rcognize this is probably not the typical finding but that's how it went down for me. The brake shoes were a mess and I ultimately decided that it was easier to just change the entire assembly.

My theory is that when I did this the weather was a little cooler and perhaps that caused the grease to thicken and making it harder to flow through the hub. This is the only time I've actually used EZ lube. Prior to this experience I have always packed hub bearings by hand.

Since it has brakes how did you see the rear seals to see if grease was getting past them?

On mine there's enough difference in seal to shoe alignment i can see rear of hub. You're able to look at an angle.

The trick is to get lighting right and turn drum so you can look for moving part.

Cussing and discussing the EZ Lube invention no matter how the thread gets started always brings out the best and worst of us. Although I'd never use the EZ lube myself as no one has ever been able to tell me why pushing the old grease out of the rear bearing into the front bearing makes sense ... I hope owners keep using this invention. I work on RV's on the side and have made lotsa money these past years by replacing brake assemblies due to EZ lube failures.

So is it alright to put some grease in but not enough to push out the old grease?

[dieselguy]

LarryS ... this invention is designed to work ONLY after you initially pump about 1 tube of grease into each hub filling the cavity between the front and rear bearings ... oddly even Dexter does not do this straight from the factory which is very telling to me. Once you get the entire cavity filled and you don't blow out the rear seal in the process ... it theoretically will work. Just 4-5 pumps at the beginning and end of each year will only create "a placebo of doing good" in your mind because as I said ... it takes usually almost a tube of grease to fill the hub the first time around. Yes I know ... there are some of you that swear by this invention ... It obviously has worked for you.

I've found that lots of things work as intended if you follow the instructions as written.

I'll bet that Dexter has cone a @#$%-ton of testing with this system and have found it to work just fine----------If you follow their instructions and BTW, use the proper grease.

Don't like it? Don't use it. How much more simple does it get?

[dieselguy]

TitanMike, I've read your position on this subject dozens of times on this form and will not argue that for some this invention does work well. No matter the reason, sometimes you have to weigh failure rate against what a given invention is designed to do. Me and dealership service techs will continue to make good money off that failure rate.

[Larry-NC]

Our little trailer (the one that actually moves) does not have this feature. Even if it did, I'd be uncomfortable using it. It's like working blind.

Would you complete an oil change on a 4, 5, or 6 gallon crankcase vehicle by just pouring in a random amount from a closed 10 gallon can?

[5picker]

So we got 2 dozen guys that say E-Z Lube hubs are junk and 2 dozen who use them per the manufacturers directions without incident.

Who wins?
Geez....

Add this to:
Gas vs diesel
Toilet paper in the toilet vs wastebasket
Tow/don't tow with a full tank of water
Tow/don't tow with the refrigerator running on propane
Tow/don't tow with tires at MAX air pressure
X brand hitch is the best
Slide toppers or no toppers
Campfires that make smoke or propane firepits
Bikes on the bumper
30a R/V plugged into a 50a receptacle with an adapter
Antifreeze or blow out
12v battery or two 6v

And the list gets longer every discussion... [emoji6]

If you have a Camco Trailer Aid for lifting tires, it becomes even easier.

[bingraham66]

I'll have look into that. I just used a wood block and scissor jack from my truck.

From everything I've read in Dexter literature, the EZ lube seems to be primarily designed for things like boat trailer, where the wheels become submerged in water. It is an easy way to push out some old grease and replace with new grease in between 'official' bearing service jobs. Even Dexter recommends removal, cleaning, inspection, and repacking of bearings. It's not terribly difficult (now that I have a grease seal removal tool), and you don't have to waste a tube of grease in each hub, which you need to do or you will never push old grease out.

I used the EZ-Lube on my TT when I brought it home and only used about half a tube of grease on ALL wheels, only pumping until grease started to come out front bearing.

This summer I removed hubs, serviced brakes (Clean and lube contact points, adjuster). Cleaned and inspected bearings, replaced dry, inserted new seal, and then applied fresh grease using my hand grease gun. Even with no grease in system it only took ONE tube for all four. Working fine and several trips since service with no issues whatever.

Hands only got greasy when cleaning out hubs initially.

What's the difference between using EZ-Lube that works like this:




Or using one of these that works the same only gets the hands greasy:




As for those who find the seals "blown out and sitting on the spindle", that is a problem totally unrelated to the EZ-Lube. Considering how much trouble people have getting the old seals out even with the proper tool I'd say that someone installed the wrong seal somewhere along the way or did so improperly. That would have been an issue with or without using the EZ-Lube.
