Hello: I have a 28ft Starcraft Aruba travel trailer with I believe to be 3500lb axles with the dexter ezlube hubs I recentley repacked the bearings for the first time ever and now the little rubber nipples are sticking out after I drove the trailer for a few miles and parked is this anything to be concerned about.

Maybe too much grease? I'd look behind the rubber and remove excess with a popsicle stick or something.

Heat expansion, don't worry about it. If you would have had hard metal bearing covers, you would have blown them off. Sounds like the rubber nipples worked fine. Might try to work the edge to get the air out.

by little rubber nipples your referring to the rubber plug dust cover that you remove to insert the grease gun nozzle ?
with a dexter ez lube, you pump a tube of grease in and the old grease pumps out the bearing closest to you and you clean it up as it comes out... what rubber nipple are you referring to ?

That diagram is misleading since you have to fill the entire axle cavity to get the grease to the outer bearing and the grease only comes only at one point at the inner bearing.
Here is where the grease exits which is on the inner face of where the grease seal fits and exits at only one small hole.
and a pic of the new grease coming out
Here is how much grease was on the inner bearing and grease seal and notice even the cavity in the grease seal wasn't full.

Just lift one side of the rubber cap to let the air out and re-seat it.
While you pump the greese in you are supposed to rotate the wheel or drum. This is to ensure the greese gets packed in evenly through out the hub and bearings.
I have had these axels on boat trailers for many years. I pump fresh grease in every month or so and have never lost a bearing or had one show marks on it. My current boat trailer is on the same set of bearings after 6 years and they look like new.
