This is a discussion thread titled "Rear Axle Rust already?", within the Engine & Drivetrain forum, part of the Technical & Vehicle Assistance Forums category.
Climed under the truck while washing it and noticed alot of rust on the rear axle The weather in this this region is good and I always hose off the salt when it snows maybe 3-4 times a year. It's an 02 model and I never go off-road, only twice, and it was hosed off underneath immediatly afterwards. Does anyone else have this problem? It's not tiny spots, it is very visible. About 30 spots, 1/2 in. in diamater all over the rear axle.
yeah...same problem. a coat of POR-15 before winter should prevent further rust, but i'm not sure of the best way to remove the rust that's on there. i'd hate to seal it underneath the paint.
The paint is being constantly chipped off from sand, rocks and rain from the road. Amsoil sells a product called Heavy Duty Metal Protector. It's great as an undercoat, lube and motorcycle chain lube. It drys to a smooth, shiney, waxy finish that does not attract dust and dirt. It's alot tougher than regular paint in the wear department as well. Just watch out for the overspray as it is real hard to remove once dry and stinks real bad when wet!
I don't consider it to be a problem, but if I did, I'd wirebrush the rust off and paint the whole thing with some Hammerite paint from the hardware store.

POR stands for Paint Over Rust, and it does what it says. Good stuff, will make you pass out from the fumes though.

i'm with ken, it'd be best to grind off the rust with a wirebrush on a die grinder or angle grinder, it's never a good idea to paint over it. i repaint semitrailers at work and it doesn't matter what kind of coating i use, if i apply it to rust it will rust again. and not stick very well either.
POR15 is a different animal and does an outstanding job relative to painting over rust and rust prevention but it's pricey. http://www.por15.com/

Ken,
Where do you find Hammerite? I checked their website and it doesn't show who carries it in the U.S. since its a product of the UK.
My local hardware store carries Hammerite brand paint in spray cans and pint & quart cans. Check around locally. I've found Hammerite paint to be far superior to Rustoleum. In all cases, remove as much rust as you can, prime well, and paint well. Two coats of primer and two-three coats of enamel work well.
Naval Jelly is a brand of a phosphoric acid product in a gel. When applied to rust (iron oxide) it converts the iron oxide to iron phosphate which is a very good base for paint. It does little or nothing on clear iron/steel. Naval Jelly and similar products do almost nothing on loose rust...scrape and wire brush first.
