Yearly trailer maintenance for me includes new bearings and brake pads needed or not. Hub turning if necessary and an in-depth inspection of the calipers. I also tune or replace anything else that may need some love. My boat and trailer are old, born in 2006. My trailer torsion "arms" are cast (correct me if I'm wrong) and rust like hell. Each year I chip the rust off and spay with oil. They still rust and each year i chip a little off, but this year holly crap. When are these not safe anymore? Anyone have any knowledge around this subject?

I think it’s time to run to 6 Robblees for some new parts! I’d rather fix it now in your driveway vs on the way to the ocean.

I’ve had decent luck spraying rust spots on my trailers with Rustoleum cold galvanizing paint, it seems to hold off the rust better than normal oil based paint.

just spray paint that silver. Good as new.

Maybe hit the new parts with fluid film.

Take a look at LPS 2 or LPS 3. That is what they are made for.

I don't think you can replace the torsion arms. They are pressed in with rubber bushings. I've had to replace a whole axle before because a spindle was bad.

Last Winter, I noticed similar scaling on the torsion arms of my 2006 EZLoader. I chipped-off all the loose stuff, wire wheeled the surfaces, treated with Ospho, and painted them with POR15. I need to pull a couple wheels, and see what they look like after a year.

Whole axle has to be replaced on that style and I would replace it personally. The integrity of torsion arm may be fine with some material being gone but I would worry about the actual weld from shaft to torsion arm being degraded.

Treat with OSPHO first, and try the brush on ZRC cold galvanizing compound...

You can probably clean it up and it might last a little longer, but each time your trailer hits a bump you're going to be looking in your rear view mirrors to see if it broke. And if it was mine, it would break at the most inopportune time.
Get a new axle, protect the new torsion arms with some type of corrosion treatment, and trailer with less worry.

Mine were about that bad when I bought my boat 4 years ago. I took a needle scaler to blast off all the big chunks then wire wheel to bare metal. Surprisingly not much steel was actually removed with all that rust. I called ez loader about it and was assured I would be fine cold galvanizing it as there is a lot more steel there then is really needed. Anyway I haven’t had any issues with them since and rust is just starting to show again through the cold galv.

Tom....

After dipping trailer in salt they have this thing called freshwater to rinse the trailer off with....replace these parts and going forward give fresh h2o a whirl after each dip.
I little Salt-Away helps also. Rust really expands making it look a lot worse than it actually is.

If you don't replace those now, one will break while you're doing 60 going downhill on a curve.

    I've decided to replace these. Thanks for everyones input. Thinking my life is worth the 2 grand for two new axles. My boat sat for close to 12 months during my corrosion fiscal. Thinking as it sat the rust took charge as I rinse my trailer pretty regular.

    I shoulda never read this thread the other day. I spun a hub the next day coming home. Trashed my spindle and now I need a new axle. I keep up on my maintenance too, go figure. How long is the lifespan on the seals on hubs on a single axle ? Based off mileage, or years ? No saltwater too. I am interested in opinions.
