Default Galvanic Corrosion

I have a 2004 Triton LT with a clam shell. Knowing about galvanic corrosion I have been keeping an eye on the frame where the axle bolts to. This past fall I knew I was going to have to do some repairs. This spring when I was getting ready to put everything away for the summer I was surprised at just how bad it had gotten.
The clam shell is now off and the axle is out. The trailer is upside down on my other trailer ready to go to a fab shop.

Good thing you're on top of things, Chris. That could've turned out really bad next season!

Here's a couple more pics.
A guy I know has a fab shop. He builds and works on a lot of hot rods and is a real good welder. He's going to get it fixed up for me.

There should be a protector between the frame and the axle mount. Those protectors last about 5 years. I've replaced mine three times and the aluminum frame has not shown any signs of GC. Trailer is an 02 triton.

that axle also looks like its on its way out, and YES< there should be a buffer between axle and trailer frame
metals just don't play happy with each other and being able to just replace a small part, makes life easier
I',m on my third axle(second one was a BAD axle from factory)
dexter axles are what I use and pay extra to have them galvanized , they last longer, my trailer is a 1997 yr model
over the yrs I had the main draw bar develop a crack at the pin hole for the tile, and had to replace that whole section, I up graded at that time and went thicker aluminum, so, should be stronger, and even added extra cross supports to help hold load better!

the last axle, I just BARELY caught in time, easy to take for granted there GOOD

I now inspect them every yr before season, better safe than sorry, and this time of yr isn;t a bad time to look, and FIX if needed!
