O'Reilly has two offerings: the National price was $17.99 a piece, while the MPS brand was $7.99. Anticipating a repacking in 10000 miles, I bought 4 MPS brand seals for the lower price.
That seal is available from parts stocking Airstream dealers.
Airstream uses it because it is "superior."
We sell hundreds of them per year.
No, they are not cheap, because they are far superior to ordinary grease seals.
I don't think I could bring myself to use a cheap grease seal, when my life and my families lives, are at stake, as well as innocent peoples, just to save a few bucks.
When it comes to safety, those that walk on the edge, ultimately pay the penalties, as well as innocent people.
Others get out of my way, cause I'm coming out in full force, safety be damned.
Safety, is always something men and women alike, tip their hats to.
I wonder how many people, especially in todays economy, would fly on an airliner, if they knew that second grade parts were used? Not very many, I would bet.
I honestly think and believe that everyone that's tows a trailer, should be exposed to a mandatory FAA "Safety Seminar."
They would all learn, in a matter of minutes, how a foolish dollar saving decision, could cost lives.
Your family, relatives and friends as well as your Airstream, will love you for it.
Davidz71, was very lucky. But, I would bet that same mishap will never happen to him again. He won't let it. Yes, even brake adjusting springs go bad and break when you least expect it, as it did to him. Some circles suggest that brake adjuster springs be replace every 2 to 3 years, or every 30,000 to 40,000 miles.
Things happen in all of our lives that are beyond our control.
Proper running gear care IS IN YOUR CONTROL.
Be safe, not sorry, when choosing running gear components. Dollars be damned.
