How to Grease Trailer Wheel Bearings with EZ Lube Grease Cert 

Thanks Mr. Hennessy !

Agreed. I "liked" for that reason. Just the facts that we need without showing his kids, cats, dogs, backstop, products in link...

vegasfordguy yes I this is the best answer . If you pump a lot of grease & you have drum brakes on this axle you will push grease past the rear seal and will contaminate your brake shoes. It is correct to jack and spin the wheel while adding grease just don’t go craze. I carry a complete bearing kit with me in my travels less than $20 in MOST cases on eBay

Desert Explorer 302 Thank you for further info! I have a vintage 1965 Trotwood trailer. Need to redo tires, and re do bearing.

My utility trailer has the same grease fitting zerk. If you have this style of grease cap it works!

The cavity would have to be full for the grease to come out the front of the bearing. The grease comes through the inner bearing , fills the cavity and then through the outer bearing.

Ditto

Me too. Why push ALL the old grease out every time? How old can it be if you do maintenance?

I absolutely agree. You just put lub in until the lub coming out looks clean. 1/4 tube at most

@@haug0099 hmm. For #3,500 axels, I find it’s more like 1/3rd of a 14 oz grease cartridge per wheel hub.

Good video

The bearing buddies that you speak of are not designed to grease the bearings😳 They have a spring in the cap and the ONLY THING it’s designed to do is when you fill that chamber with grease and then put an extra pump or two in it …..until that spring comes back halfway. it pre-loads the grease so there may be one or two psi inside the bearing assembly❤️ so when you drive to the boat launch your bearings generate heat that warms the grease and expands it, as the grease expands it pushes out on that spring a little more….. THEN when you take and dunk the ENTIRE bearing assembly in the COLD water it quickly contracts the grease in the hub and without the BEARING BUDDIES that grease could create a negative pressure while underwater! The seals on the bearings are slanted in towards the bearing because job is to KEEP GREASE IN🙂 so if there becomes negative pressure in the bearing assembly it will SUCK WATER INTO THE BEARING ASSEMBLY 🤮 and of course that water can turn into steam as you’re driving home and OVER TIME DEVELOPE’S RUST overtime ruins the back or the inner bearing. The bearing buddy is an excellent tool for boaters but most people don’t understand the BEARING BUDDIES PURPOSE🌹 I am going to attempt to use both of these because I think changing the grease halfway through the season in eight minutes would be a great benefit for me. ❤️GOD Bless our America🇺🇸

Just visually inspect them, If there is metal shavings in the grease or if when clean the balls look worn, then it would be time to replace them.

The old grease will be somewhat runny like warm Jell-O whereas the new grease will be firm and perhaps a different color from the old grease.

Ya cant turn a fixed axle wheel !

Good input. Thanks for taking time to comment !

No, I don't think so.

Yes, with a regular grease zerk but this grease zerk is different. The Dexter E-Z Lube system uses a tube from the grease cert to the back bearing so that the fresh grease pushes the old grease out from the back toward the front.

Yes, usually brakes on both axles is another option.

Dude it ain't a CERT!!!! THATS A BREATH MINT. ZERK!! ZERK you nerd

@@donschlonski2936 Minty fresh.

Ha ! I was 53 years old before I realized my hearing (or lack there of) had me thinking that fitting was called a sert, as in "insert grease here". If I hadn't made this video and had people correct me, I'd probably still be calling it a Cert !

Jim Thomas yea it's a zerk! And I advise people not to use it unless you take out the outer bearing first, if not the seal just usually comes out, due to the large air gap between the two bearings not letting you see grease flow.

Look up Dexter EZ Lube online and see what you can find out about the system.

Jim Thomas thank you

+littletoy01 If they are on a utility trailer chances are that it s not the Dexter E-Z Lube, but if they are on a RV then look inside the RV cabinets and see if you can find a manual on the axels. If there is no manual, then it is probably just buddy bearing.

The way it is engineered, the pressure of the grease just pushes thru a center straw to the back and then it flows from the back thru the bearings to a open portal in the front, so not much pressure is allowed to build up.

10-4 learn something new , thanks

Depends on the load and the mileage - hauling heavy loads like heavy machinery on long haul trips, then every 3000 miles would be about right. .. lighter loads 4000 + ought to be OK

Armando Perez most trailer supply stores have them or also utility trailer supply stores Also amazon

Armando Perez they sell them on Amazon. Pack of four is like less than $5

Not sure of the PSI but the cartridge is 14 oz. I have never used a gun with a bleeder valve but most of my problems I have with my grease gun are from getting air bubbles that cause a failure to feed, so a bleeder valve might help... but I'm not sure. Best wishes - BTW Cute thumbnail Lisa !

Thanks!

Jim, when installing a new cartridge pack the head of the gun with grease from the bottom of the new cartridge, I find that it eliminated 90 percent of air pockets on my gun and starts pumping right away. Hopefully not telling you something you already know

Joe Rasberry With an EZ Lube axle, yes. You should still repack the standard way periodically to make sure everything still looks good.

Bike and motorcycle chains, trailer hitches and the paper towels help start damp brush piles on fire. Also, used motor oil mixed two parts diesel to one part motor oil, makes pretty good wood preservative when sprayed onto a trailer deck (top and bottom). In the summertime, the wood really soaks it up.

I usually just get my grease at Walmart but I try and go with "High Pressure" for my RV trailer and larger utility trailer or "Marine" grease for the boat trailer.

The bearing are top quality, this is for a boat. Your bearings go under water every time you launch a boat. YOU HAVE TO OCCASIONALLY REPLACE THE GREASE DUE TO THIS. It's very important. Otherwise, I replace mine once every couple/few years with a regular trailer

bearings are all made in China now

YEG Drone Photography - the video you just watched was for a boat trailer. Boat trailer go under water all the time. They go out extremely father than a Car you are comparing to.

@@Dojautlopez Haug009 - this is a camper trailer, NOT a boat trailer. It says Jayco on the fender. Plus you would never put a dust cover over your lug nuts on a boat trailer.

mdees88 you are correct. Idk why I thought it was a boat trailer.

Ha ! ... and all these years I have been calling it a cert ! Funny what being half deaf can get started ;-) Thanks for the correction !

@Joe Casson people that print manuals are often idiots anyway. The circle of life

zerk

Better to have bearings packed than to run a trailer on bearings without grease.

Kirk Klag you missed the guys point completely

Not true. You simply feel the bearings/hub after driving a while, they will be hot if bearings going bad. Mechanics have been doing that for 50+ years for a reason

@@Nate_HarietteRU-vid_Adventure No he didn't. Zerg fitting are there to add lub so you don't have to repack it. You don't have to tear out the bearings every time you add lube

This usually just pushes the seal out anyway.

Watch it again, this is a different system. Clearly explained and proper cautions given regarding not getting grease on your brakes.

You've never disassembled a hub and cleaned & repacked the bearings, have ya Gavno? This is much faster and easier if you have the E-Z Lube system installed.

@@jcwoods2311 so what is the point of having ez lube system if you still need to "disassembled a hub and cleaned & repacked the bearings", eh?

With the Dexter technology, the grease follows the path of least resistance and is easily pumped thru the center soda straw tube to the back bearing and then the fresh grease pushes the old grease out the front. There is very little pressure on the back seal.

You are a nerd

Brian Schmidt I have found with mine that any thermal expansion is outward into the rubber plug making it expand outward. After parking and hubs cool it contracts the plug inward

Dumb ass. Then why do the manuals of Dexter axles say to pump until you see some old grease?

check out the dexter EZ Lube website Rick

You have no idea what you're talking about...

Dave Maple I was talking to Rick...

Rick. I can see your concern. A buddy bearing / easy lube / grease cert is not the best way to deal with the back bearing. I will change the name of this video and add a more appropriate description to reflect the difference between this type lube system and the "proper" method... which can be seen in my other video called " How to Pack / Grease Trailer Wheel Bearings". I appreciate your comment. Best wishes - Jim

Rick Drysdale All I can say is that I am glad I did not follow the directions in the above video. I am getting ready to take a 7,000 mile road trip and though since I have been greesing my bearings using the above method I better do a complete teardown and inspect the inside of the assembly. Upon taking the hub off thee first think I noticed was that greese was everywhere. Zon the brake pads, all over the backing plate,all over everything,what a mess. I completely disassembled everything and greesed the bearings with a $10 bearing greese tool and cleaned everything up and put it all back together and they are good as new. Rick Drysdale is right folks, don't follow this video as it may mean trouble down the road.
