    Well I think I am going to give a go at re-packing my bearings myself...I have a 1991 Coleman Roanoke. Is this too daunting to take on myself, I am pretty handy. I want to save myself the expense of having someone else do it for me...most importantly what type of grease to I need to re-pack with and I need brand names/types that I can find at Wal-mart or local auto parts store.

    Well, I buy this stuff labeled "axel bearing grease". :)

    It comes in a small tub and you just scoop it up in your hand and press it into and through the bearing until all the dirty grease is pressed out.

    Do not forget to get both bearings on both wheels and have a spare inner and outer seal handy "just in case" you mess one up.

    The last batch I got was brand named Gunk I belive.

    I like the red colored stuff as it makes it easier to see where the old grease ends and the new grease begins.

    It's really not to bad and well worth the work.

    You can get also get an attachment for a grease gun that has two plastic"plates". After you clean the bearings you clamp these plates around the bearing and it forces the grease into the rollers. Should be able to get it a Napa or equivalent.

    Well I took the wheel off and took the bearings out, when I took the nut off, there was no washer behind it! and the front bearing had the tapered side pointing towards me! I went and purchased new bearings and races I have to go pick up two washers this afternoon from a place that sells trailers; hopefully I can get all this back together before saturday so i can go camping this weekend.

    When putting the bearing back in the hub, they both go in with the tapered ends facing one another correct?

    Also do I have to use a brass punch to seat the races in the hub with or can I use one of my nail sets?

    As long as the nail sets aren't hardened, then they're fine (albeit generally a nail set is a bit shorter than I'm comfortable using, and hardened to boot). Personally I use a piece of key stock and it works fine. Brass is nice because it won't nick up the bore like key stock sometimes can.

    And yes, the bearings face each other. If they face the same direction, it'd be impossible to get the wheel to stay straight as it would walk to one side or the other.

    Well my Labor Day Weekend of camping is shot! Freakin guy at the parts store gave me the wrong damn size bearings, found that out after i had already hammered in the races on both ends and inserted the inner bearing and the grease seal!!!!!! I am pissed!!! I am going to make him take it all out of the hub and get new bearings and all, I am not paying another cent!

    I don't want to sound like I'm sticking up for the parts guy on this one but I think the problems encountered where caused by both of you. Since it seems that you may not have replaced wheel bearings before you should have compared the old bearings against the new ones before installing the races. Even today I compare the parts I by before installing them (and I had been a mechanic in a past career).
    The positive side of this experience is that these problems happened at home and not because a bearing went out on the way to the campsite and, the next time you repair something you won't forget the wrong parts that you were given this time.

    Trailers are the hardest things to get bearings for. Just because the parts book says this bearing is what is in there doesn't mean that's what is thare ( as you found out). The only way to buy bearings is to take the old one in and comapre the numbers on it to a cross reference chart and get the proper replacement.

    I agree with Alex. I just installed brakes on our 2007 Flagstaff with an AL-KO axle. The same axle number could have two different bearings and seals. I had to check what was installed before ordering parts.

    I ordered bearings from Internet and got the wrong ones, they were not both the same size, had to get them from the auto parts store the second time...they are right you need to pull the old one and know the number...

    As a former manager of a NAPA store, I can say that most bearings and races are stamped with a number. This number is either a standard bearing number or can be crossed referenced to a standard bearing number. It can also be cross-referenced to the make-model of trailer that it applies to. Pull all races and bearings and take them to a reputable parts store.........not an "Advance Auto" with no reference books, only computers.

    As a side note to the person that uses "red" grease to distinguish when the old grease is out of the bearing. Good call.....one for the obvious, but two...normally red grease indicates a higher heat rating, ie less prone to breakdown.

    Also, the bearing buddy deal with grease fittings accesable for easy lubing.....seems nice....but doesn't lube inner bearing well. They push old grease from outer bearing into inner bearing. Overgreasing will blow out inner seal.

    Happy Camping.

    hey to all above i did get to go on my labor day retreat, but not before i stayed up till 1130pm at night working on my bearings and getting it all ready to go...and to barb_dave who "sided on behalf of the auto parts guy" it was totally his fault; i might be new to popup camping but not an idiot. i took the old bearings and races to him just so happened to be a bumper to bumper store that has parts books and he cross referenced the numbers and and he handed me some new bearings and said here are your new bearings i hope you have a good trip this weekend! so to sum it up again, total mistake on the parts guy, when you go into an autoparts store with the old parts you are supposed to trust the guys ability to give you the correct parts...the only thing that i will do different next time is when i get back to the house with new bearings i will slide them on the spindle to make sure each one fits...because there is an autoparts store guy somewhere in your town that doesn't know how to read numbers

    Please not there is a difference between Bearing Buddies and EZ-Lube Axles. The EZ Lube Axles have a grease fitting on the spindle that allows you to pump grease into the space behind the inner bearing between the inner bearing and the seal. That forces the old grease forward through the inner bearing, then through the outer bearing, and out into the cup. In some cases, it'll blow out the rear seal instead of oozing through the bearings. An over-zealous grease gun (or a pneumatic one) will do that very easily.

    As has been mentioned here before, Bearing Buddies are a waste for trailer axles, except in cases where the axle will be submerged (e.g. boat or jet ski trailers). They have a purpose; popup campers are not one of them.
