    Too Much Grease!

    Took our 397TH in for some warranty work (been waiting on parts). I told the service writer if they had time to pack the wheel bearings, we've had our 5th wheel for almost a year and put a lot of miles on it. He calls me later and asked if I had ever lubed the wheel bearings, I told him I have not. Apparently the brakes on 4 wheels have grease on them and need replaced. Has anyone else had a problem with too much grease in the wheel bearings from the factory? 7000lb Dexter axels by the way. Still waiting to see who pays for this, hope it's not me.

    Mostly not too much grease, usually mis-applied grease, as a result of shoddy assembly. You might want to check them out yourself just to be sure they aren't getting a bit overzealous and replacing parts that can be cleaned. But if grease has soaked the brake shoes, there isn't a lot to be done about that.

    Grease on brakes has been a problem for a long time. It has improved and is happening far less but it still does happen. If you search greasy brakes you will find plenty to read.

    If this is a warranty item ( it should be) and all were greased I would have them replace the all the brakes. If they want you to pay call GD and double check with service that it was issued as a claim and if not push for it.

    Grease on brakes is common straight from factory. Usually bad seals. I recommend anyone with a new trailer check the brakes for leaking seals. On our brand new 2019 351M, grease was on the brakes when I changed to disc brakes after 6 months of owning it.

    Which is why I disagree with those that believe servicing the bearings only requires pumping grease into the hubs using the hub zerks. My guess is your leaking seals are a direct result of an overzealous worker with a very heavy trigger finger on the air powered grease gun.

    You cant clean grease off brake pads, they need to be replaced. You can clean the drums though.

    I got good news! Grand Design is covering this and the dealer is mailing me a check as I already paid for repairs and have our toy hauler back home! The dealer and Grand Design have taken pretty good care of us since we bought our Momentum. Biggest problem has been getting parts for the repairs, it takes a while, seems like Covid has slowed everything down. Thankfully, it's all been little stuff and we can still enjoy our toy hauler (and the toy).

    Good t hear this has worked out for you. Grand Design’s customer service has a good reputation.
    For future reference avoid using the grease zerks to lube your bearings. The only way to properly lube your bearings is to disassemble, clean, repack and install new seals. What is occurring with both Lippert and Dexter axles is they do not contain a relief port for excess grease to come out, like on marine trailer axles. Due to this lack of a relief port excess grease and pressure flow past the seal and contaminate the brakes. The supposedly proper method is to jack the tire off the ground and spin the assembly while pumping in grease, still not a good idea. Grease will become contaminated from normal use, and can break down over long periods of time, however, sealed in a hub, with no direct light exposure this does not reduce the volume of the grease in the hub. So pumping in more grease each season is a bad practice.

    Not 100% accurate. The grease that gets pumped in, I'm talking EZ-Lube system, makes it's way through the axle stub, through the bearings, and out the end of the axle stub. That is where the excess grease comes out. I've used it in the past, but it really is unnecessary. Consider the wheel bearings in your car, they don't get fresh grease and rarely fail. IMO it's best to disassemble the bearings to check for proper assembly and amount of grease when you first take possession. Some of these trailers come from the factory with grease in the brake area, and dinged and damaged grease seals. Best to make sure all is well before doing anything.

    Once you know all is well, the you can disassemble and repack bearings every few years if you so desire. All depends on how many miles you travel, and the terrain you cover.
