Hub Greese Seal Price Shock

I just bought a set of four wheel seals and I'm still in shock! $11.50 each - and that price is suppose to be discounted! My Airstream supplier was actually slightly less - but with shipping it came out within a dollar or two difference for the four seals. The last time I bought seals - for my Award TT - was about 5 years ago and I know I didn't pay more than $3.50 each. Incidentally, the Award uses virtually the same suspension and axle as the Airstream. These toys are sure getting expensive!

Bearing seals

I purchased a pair of them the other day from Camper's Inn located in Nashua, NH the other day and I think the pair was about $10. I have to get some more for the other set of wheels. I'll let you know the exact price.

BTW I have to replace an outer bearing on my 2001 30' and I'm having a terrible time getting the interface for the part numbers from AS to Dexter to Timken. When you pulled your wheel, did you happen to write down the bearing and cone numbers?

I plan to repack the bearings this weekend. I was able to get the seal part number from Marty's RV in Massachusetts ahead of time. The 2000 and the 2001 are probably the same - but somewhere along the way the Excellas went from 8300 lbs to 8900 lbs maximum. I'm not sure if this affected the axle assembly. In any event, I'll mark down the bearing number this weekend and get back to you.

You must be a member of the New England Unit of the WBCCI. If so, were you at the recent rally in Freeport?

Cracker,

We are members of the White Mountain Unit. This year is going to be tough in attending any events. We still have a child in high school, and he is very busy with life. Being responsible parents, we can't leave him alone while we are off airstreaming. That being said, we are planning a trip this summer without him, he will stay with relatives. Unfortunately, the trip doesn't include WBCCI events.

Let me know the numbers you find on the bearings. I think my axels are the same as yours. Somehow I remember the GVW and 8200 lbs.

Mark

Question Price of seals..

The price of seals vary greatly.. My Hubby just replaced all the seals on our Argosy for $16.00 Total.. not each but TOTAL.. and that is Canadian dollars.. got them local from a trailer fabricating place.. these are exactly the same seals as being charged an arm and a leg for at other places..

I'm in the NewEngland unit, but I didn't make it to the rally last weekend. Heard it was quite the mud-fest, though.

I will be at the Rendezvous in Saco, which starts tomorrow...

I'm beginning to feel like I've been had! I bought my seals at the local NAPA store where my company has a very large account. I'm going to do a bit more checking just to make sure somebody didn't goof up.

Also, I went to buy grease for the bearings - using a bit more research than I would have in the past - and I found that there are numerous types of grease compounds now offered. This may be nothing new to more active grease monkeys but, for a shade-tree mechanic, I stood there reading the labels and scratching my head! All of the labels advised against mixing different types. Can anyone tell me, with authority, what type grease Airstream, or the wheel OEM, packs the bearings with? The alternative is, of course, to completely wash the old grease out - but that's a real pain!

I'm still doing my prep work - so I won't be at the rendezvous in Saco. I'm overdue to start travelling and camping!

Cracker,

If you go to the Dexter Axle web page, they have a listing of the greases they recommend for their bearings. It is my understanding the wheels we have on our trailers are Dexter 12 X 2.

You should clean all the grease out of the bearing each time you repack, it is very easy, one large can of spray brake cleaner will do all four wheels. Marvin

I opened the Dexter Axle website - www.dexteraxle.com - as you suggested. It provides an excellent "how to" guide for repacking the bearings, replacing the seals, and adjusting the brakes - as well as the products to be used. It was a good refresher course for me and it served to correct some bad habits (---like driving out the old seals using the bearing as an anvil!) Additionally, Dexter recommends using PERMATEX on the rim of the new seals - which I had never done. The "lash" adjustment procedure for the spindle nut had some minor differences that I found to be of interest also.

The Outer bearing number is "China" LM 67048 UCF4. The inner bearing number is 7009A (25580) VPZ-15. For the life of me I could not locate or determine the manufacturer - however these are the original bearings for the Dexter axle. I got both of my street-side bearings done on Saturday. It was purely an exercise - since everything was in good shape. I'm not sure how the OEM packs the bearings - but let me tell you - there was enough grease in the inside hub to fill a coffee cup! I passed on Dexter's recommendation to coat the outer rim of the seals with PERMATEX. I've never done that before and Dexter didn't mention the particular type of PERMATEX to use. There was certainly nothing evident on the seals I pulled so I'm comfortable with my decision. I was concerned that the brakes might have the "automatic adjusters" but I was pleased to find that they were the old manual types. I've had a lot of trouble with automatic adjusters in my younger "grease monkey" days. I was surprised to find that you can get enough lift out of two 2 x 8's to raise the unsupported tire free and clear of the ground. I had a stack of four 2 X 8's and it was definitely overkill.
