Hey guy just thought i would post about this, i'll add a picture later...

I was pulling the wheels off my boat trailer today to put new tires on, too bad UPS only dropped off one tire when i ordered two but its not there fault and the dealer is shipping another but it will take another five days.. ARGGHHH

But anyway.. I was surprised to find a grease zerk on the back of the hubs. It's nice that its there though! I took the caps off the hubs thinking i would clean, repack, and inspect them. But when i took off the caps i found nice clean fresh grease and the bearings are nice and smooth when spun by hand. I was even going to put bearing buddies on it but now i don't why i should bother if i already have a way to put a little grease in now and then!

Anyway, anyone had a trailer like this? I have dealt with a lot of utility and camper trailers over the years, but never have i come across one with an actual grease zerk. Its factory too, not added, there is a slightly embossed spot on the rotor that was drilled and tapped for the zerk so that it sits at an angle away from the hub to let you get a grease gun on there easier.

My trailer has grease zerk fittings too, on the inside of the hub. You remove the plug on the dust cap first, then shoot grease through.

I couldn't ever get clean grease to come out, so I'm going to clean/repack the bearings, then add grease through the fitting to fill it.

I'm guessing you must have an older trailer then too. Mines a 68/69 Dilly Trailers S-16. Not totally sure on the date as its hard to read the tag on the back end of the frame.

I took the dust cap off on one side and pumped some fresh grease in using the zerk on the back and had fresh grease coming out the front after a couple pumps, so its definitely flowing through nice on these.

On another note, i went to the other side and put two pumps into that one and it popped the dust cap loose.. Must have a good seal in there for pressure to build and pop that out a bit. The rear seals appear good as there isn't any grease coming out back there when i pump in some fresh grease using the zerk.

I'll let it go for now, i don't think its worth tearing them all apart as clean and smooth as everything seems to be in there. Just surprised me seeing a zerk back there! If i hadn't taken off the wheels to replace the tires chances are i never would have known.

If I remember, I think mine's around an '86 model.

My wheels were so dirty when I bought this trailer that I never saw the plugs in the dust caps. I just started pumping grease in to see what would happen. Then POW - the plug flew out like 6 feet away.

i have the same hubs, works well i pump a squirt of grease into it every month or so, it puts freash grease into bearing and old grease comes out.

i lost a dust cap and bering went out, can't find a new cap.
found one that fits hub but not deep enouph, so i am going to use cap and cut top off, and retrofit a deeper cap into ine one that fits the hub, i hope this will work, wisj me luck:D

they work good just dont loose cap!!!!

Sounds like Super-Lube hubs http://www.tiedown.com/ahubs.html

I have Super-Lube Spindles (same principle) on my trailer and they seem to work great.

You can get replacement caps for a couple of bucks each from Tie-Down or Champion Trailer if you need them.
