EZLube on 365BHS, Remove Wheels?

WeylanBryant · 09-08-2011, 12:55 PM

Greetings... We have a 2011 365BHS that has the EZLube Axle. I can't seem to figure out how to remove what I think is the hub cap to access the EZLube Grease Fitting. The hub cap simply will NOT come off. Is it an integral part of the wheel? Thanks!!

The end of the hub will pop off with a screwdriver. You can grease the wheel through the end. Very easy to grease hub.

As taylor J mentioned, pop of the center caps with a really flat screwdriver. Don't over fill them as it could lead to brake failure with potential grease getting in your drums. I think 4-5 pumps would suffice on each. Mine only took about 4 on avg before wanting to bulge.

Thanks taylorj and 3'senough... That's what I ***thought***, but wasn't sure how much "elbow" grease I should put behind "popping off" the end of the hub.

I hear you, 3's, in re: NOT over filling them - the owner's manual makes that VERY clear. The OM ***SPECIFICALLY*** says to watch for the grease coming out. Since I'm just doing PREVENTIVE maintenance, I'll probably only pump 3-5 times and call it a day. They've been working FINE (not overheating, as far as I can tell), so I just want to keep them running nicely. THAT SAID... This will be the FIRST TIME (I purchased the rig new and understand the JayCo does NOT typically "fill" the hubs with grease) I'm doing this on these axles. As such, do you think I'll need more than the 3-5, or just watch CAREFULLY and play by "eye/ear"?

Take it slow and watch the seals. I guess it depends on the tech who filled them initially for how much each will take. The second you see grease or 3-5 pumps, which ever comes first I would stop.

They also suggest you turn the wheels while pumping the grease. Of course you would have to use a jack to do this.

Will do 3's. Thanks for the tips!!

Crabman... Tough to do unless the rigs jacked up, like you say. I think I'll put 1-2 "squeezes" into each hub, drive around the block, and then finish with 2-3 per hub. That SHOULD get us to where we need to be.

Thanks all!!

The service manager at my selling dealership told me that the proper way to add grease is to jack trailer up by frame until the tire is off the ground. Then you add grease while turning the wheel at the same time. He also stated that if you add grease without having the tire off the ground and turning that you stand a chance of blowing a seal out.

You must raise the wheel and slowly turn it while the new grease is going in. Also it is advisable to keep pumping the grease very slowly until you see the new grease coming out. If you do not rotate the wheel the grease cannot flow successfully. These systems require a lot of grease... much, much more than the normal bearing disassembly method.

See the grease coming out???? NOOOOOOO just 2 or 3 pumps is all you should give it.. otherwise you risk blowing a grease seal and filling the brake drum with grease...not a good thing...

I agree with Seann, 2 for sure and 3 pumps maybe.

unfortunately this system requires replacing the old grease just as if you were repacking the bearings manually. You never use old grease to repack wheel bearings. It is messy but necessary. You slowly rotate the wheel and slowly pump in new grease.

Other than into your brakes, where does this old grease go? I am really curious.

volwing1 · 09-11-2011, 06:37 AM

The grease flows through the bearings and back out the outside of the hub near the Zerk fitting.

bad99ram · 09-11-2011, 09:02 AM

When you pump grease into a EZ lube system, it goes in from behind the inner bearing and pushes out from the backside of the outer bearing. The book states that when you see fresh gease coming out from the outer bearing to stop. This system is far different than the old Bearing Buddies.

Here is a PFD on Dexter`s Easy Lube Axles procedure for greasing bearings. # 3 States "Pump grease into zerk. The old displaced grease will begin to flow back out the cap around the grease gun nozzle". So volwing1 makes a valid point.

You have to replace the grease with new. I would use a synthetic grease. Rotation of the wheel is highly recommended. Never jack your 365BHS up by the frame. For multiple reasons I would jack it by the axle. If grease gets on the brakes you need a new bearing because you have blown the seal. Grease will come back into the wheel hub, I highly recommend trying to wipe out much of it as possible. If you blow the seal you dealer should of been doing it for you in the first place.

4. To raise the RV, place the jack (hydraulic
or screw) under the main frame rail. It
must be just ahead of the front tire or just
behind the rear tire.

Mocamper this is right out of the Jayco Owners manual

Ok, so that is how it is supposed to work. I had the same system on our Montana and the old grease found it's way into the brakes. There was nothing wrong with the bearings. The bearings were repacked by hand after the shop tech replaced the grease covered brake linings. The bearing pack and seal job was fairly inexpencive. The brakes were another expense.

So for me, two pumps every other year and then do it by hand. Our trailer is only pulled about 3000 miles a year.
