Hub grease seal.

Yep blew one, actually believe it was defective from factory. As the complete axle was replaced and it never seemed to take grease. Well. they found it when they took it off. So, now I have not only a new seal, but a new backing plate as well.
Ye ha!

and no I couldn't do it my self. I don't have the tools.

The original owner of my boat and boat trailer simply used the EZ lube system instead of repacking the bearings. When I took it apart last year to repack the bearings I found a very brown inner bearing on one side that I had to replace and a TON of old grease throughout the entire hub on each side. What a mess!!! I'll stick with repacking them manually thanks.

2015 my DRW was delivered to me with 4,000 miles on it or so. I towed til the next summer then back to MORryde, that added another 4k or so. Later that fall with at least another 4k I raised up the RV and checked the bearing play doing the push/pull on the user edge of the tires. The play was well within spec. So I had a friend spin one tire at a time while I pumped the grease into the EZ Lube ZERK as fast as I could stopping to wipe the old grease off as it came out. I stopped once the fresh grease started coming out.

I did the above because I didn't trust the grease or how well it was greased.

Until a person actually uses the system they really don't know.

I agree nothing replaces hand packing bearings , EZ lube is asking for problems .
Bosh. Although I've used the EZ Lube grease zerk in the past, I've come to believe that it isn't really necessary. Once the grease is in the wheel bearings and behind the seals, it isn't going anywhere, so there's no real need to add new grease. In all the years I've been driving, over 56 years, I've never disassembled a wheel bearing, on any vehicle, simply to regrease it. I might use the EZ Lube zerk after a few years to put in some fresh grease, just depends on how I feel about it at the time.

I pulled wheels apart last year to check brake pads, and wheel bearings and grease were just fine. But after looking at the nicks and dings near the seal surfaces, I'm surprised more don't leak grease directly from the factory. It looked like they stood back about 3 feet and threw the pieces on, and called it good. This is on a 10 year old toyhauler with around 25,000 miles.

IMO annual repacking of wheel bearings is a waste of time and resources. Maybe every 3-5 years if a person were really anal about stuff like this.

EZ lube with disk brakes is a great system. BUT I went to another level with changing mine to oil bath with US Made National Oil bath Seals. Nice system but you need to use QUALITY parts.

Absolutely NOTHING wrong with using the EZ Lube system. Use quality synthetic grease in a REGULAR grease gun, rotate tire while pumping while wiping off used grease as it comes out. Stop pumping and wipe off excess when fresh grease appears.

Problem is they most likely used no name Chinese made seals!
