Two years ago, after our September beach trip, I parked my trailer at my house and didn't touch it until the following year when it was time to leave again. As I hooked it up I noticed this:

Yes, that is daylight. I honestly had never considered this sort of failure, and am eternally grateful that it failed in the yard and not five miles down the road. Needless to say the boat didn't make it to the beach that year but I did order a replacement axle for this year. The trailer has a 50" spring center which greatly limited my choices but I found a
nearly perfect match at Eastern Marine (aka Trailer Parts Superstore).
When I jacked up the broken side of the trailer the other side gave way:

The corrosion at the ends was unbelievable. I have had this trailer since 1991 and it looks like the axle was made from plain painted steel 2" box, possibly without treating the welds where the spindles were attached. The center still had intact blue paint, but the areas under the clamps was gone. The new axle is smaller, galvanized, and has spray galv on the welds. It is about 1" longer than the original at each end, but the wheels are still within the fenders.


I had to change from 1" bearings to 1-1/16" bearings which turned out to be a good thing, as the outer races were in poor shape. So with new bearings and seals I assembled the complete axle:

and slid it under the trailer with new hardware.

It feels SO good to know that this is now solid. If I ever have enough free time I may replace the leaf springs - they could be a bit softer next time - and clean up the hubs, and replace the crossbeams on the trailer since both have been welded... but I still think I will end up with a Getaway so the trailer situation may change anyway.
So... inspect your trailers regularly!!
