It is a pretty easy system but make sure to check your grease levels by adding grease now and then and you will be a happy camper....
The bearings were not a tube and a half low, they were actually packed properly the way wheel bearings are supposed to be packed. You just filled a cavity full of grease that is not meant to have grease in it. All that extra grease does in there is hold the heat generated rolling down the road up against the axle instead allowing it to dissipate through the air gap to the hub the way wheel bearing have done since they were originally designed. I can tell you it is no fun trying to clean coked grease off an axle.

What kinda of axle do you have, if you do not pump the grease in until it starts to come out you will not be filling the outside bearing only the inside. Am I doing this incorrect for a AL-KO rubber torsion axle? ..... my axle 4000lbs cap. x2 and is on a Rockwood 8289WS with the ultra lube system.

The only way you can get grease through the outside bearing is to fill the middle cavity that John (TheSasks) refers to, if you are using the easy lube hubs. What John is saying that it is best if that cavity is not full of grease, but kept empty to dissipate some of the bearing heat. The only way to keep that empty is to hand pack the bearings.

I use the Easy-Lube hubs. Except for a broken square flange that caused that rear seal to leak due to the brake assembly coming loose , I haven't had a problem. The repair shop that rewelded the flange checked all of my rear seals, and each were letting a little grease get by. The repair shop guy does not think using the Easy-Lube hubs caused the leaking seals.....they just plumb wear out or fail due to age.

Except for the broken square flange resulting in the brake assembly coming loose, my bearings have always stayed nice and cool.....no trouble keeping my fingers on the dust caps during my check at rest stops. Now, that was a whole different ball game with the square flange broke loose.....ouch !!!

Explain why it is designed that way and the mfgs recommend filling it. Lube is many times used to dissapate heat, not retain it. Never heard of it retaining heat on a bearing. Never too old to learn!

You did what the mfgs recommend. Just don't get carried away. If you get too much in them, they will bleed grease out around the rubber plug and sling it all over the wheels & tires. Mess to clean. Ask me how I know this!

At 25,000 miles, I did have the dealer re-pack and inspect the bearings, adjust the brakes, and replace the seals. All was well. No signs of wear or deterioration.

Thanks every one

The reason for my asking is when I was 22 I sat out in the desert , 108 deg. with a boat with a burned bearing with nothing but Ice chest water to drink from 9am till 7pm while the owner drove back to town to get parts.I know if I meet specs on the grease it should be ok but I still just don't feel good mixing products. I'm a steam engineer at a hosp and have seen grease get funky. I just don't want to pack bearings on a brand new trailer but when I do I'll buy spare bearings and seals , carry grease and tools . When I pack bearings I also stuff the hubs with grease so these new hubs with zerks sounds like a good thing to me. I know there are two schools of thought on greasing bearings, I'v had 2 supervisors that claim too much grease will overheat the bearing and when they turned their backs I pumped it full and never burned a bearing. They both had degrees. I always carry a thermal gun with me and every pit stop I shoot the bearings to see whats going on. this last trip it was 103deg outside by needles and I had 2 hubs at 136 and 2 at 143. 7 degrees diference is not bad, probably due to to brake shoes dragging.Once again thanks everyone for all the info, you guys know your stuff and your helping me learn. Mike

2 is the correct answer as 2/500 miles is a little excessive. 2/5,000 is about right IMO.

Thats what I was thinking. I'd be pumping the stuffing out of the bearings at 2 per 500.

I've used Lucas Red N Tacky for my other trailers without problems.

another product which has Xcellent reviews is JT6:
