EZ Lube Fail

I have never used the EZ Lube zerk on my axle, read to many cautions from more experienced members than myself.

We purchased our '12 29QBH private party in Feb 2014. It is in great shape, you could tell the previous owner really cared for it and was very sad he was losing it do to a divorce.

Since owning we have used it twice, both short trips on realtively flat routes. Both times I felt as though I wasn't getting the breaking that I expected. At first I thought it was just pulling a much heavier trailer, then I thought maybe my P2 needed to be readjusted. But since the trips were short and flat I didn't think much about it.

This weekend we are heading up high in Sierra Neveda Mts, which at one point there is 11 mile 9% grade. I wanted to make sure the breaks and controller were A-OK. After messing with the controller I couldn't get it where I liked it. Since I was out of time I took it to a friends tire shop asked him to repack the bearings and adjust the breaks.

10 min later I got the picture below texted to me , clearly the previous owner did use the EZ lub zerk, blew out the seals on each wheel and the brake assmeblies were full of greese.

On a positive note, my 2012 JayFlight 29QBH does have self adjusting breaks. My 2012 JayFlight 26BH didn't.

Wow, that's ugly! Glad you found out this way rather than the "bad" way.

That's what mine looked like, I hand pack'em now AND take out all the extra grease that is floating around in there. That bit me too, Brakes get hot grease gets loose.

Mine came from Jayco full of grease. You will sure like having brakes.
I will never use those Zerks. Have them packed manually every other year.

I am one that likes this option. But you need to understand that if grease is not coming out the front then its going out the back. There is no front seal on this system so there is no reason that pressure is pushing on your rear seal. The excess comes out the front side. I think that what actually causes this issue is old hard grease in the front bearing blocks the grease from coming out the front and people blow out the rear seal before they blow out the old hard grease. The proper procedure is to jack up the wheel, add a pump of grease and rotate the wheel. If you don't see old grease coming out the front side then it's going out the back, that's when you should stop and pull the hub. If it comes out the front it will not build up pressure on the seal, it can't do that.

I never touched mine and after about a year I noticed my brakes weren't working, took them apart and they were all packed with grease. I would never use the ez lube zerk.

This is what was explained to me and shown to me the first time I had to do this by myself. Works correctly every time and I do it approx. every 4,000 miles. The problem is buying used and that person never maintaining the TT resulting in old hard grease.

When I took delivery my technician told me never to use it. He said Jayco recommends repacking bearings once a year or 12000 miles. He said if you follow this recommendation there is no need to add grease.

Makes me wonder why they have EZ lube axles on their trailers if they're just going to tell you not to use them?
