All Toyota trucks I see have there rear axles rusty. Is there any way to prvent or coat them woith something better. My fience's father has a '04 Tacoma Double Cab V-6 4 X 4 with 27k and the rear axles is already starting to rust! (IMG:style_emoticons/default/w00t.gif)

Are you worried about how it looks or whether it will rust through? It will last as long as the vehicle and is not a problem. If you want it to look good use a specialist paint that can be applied to rusty surfaces.

Are you talking about the axle housing or the axles themselves? Why the heck are you pulling the axles at 27K? Don't mean to offend you but you can't see the axles unless you pull them out of the housing. I have just never heard anyone pulling axles at 27K. Can you be more specific.

I know AXLES are insiode the HOUSING and the housing and PUMPKIN are oon peice on imports. The HOUSING IS RUSTING!!

You may check out any POR-15 website by doing a Google search. However, this stuff is nasty to get on you when in use, so I'd sure look at their instructions closely at the web site. The axle can then be topcoated with their product or any other, such as Rustoleum paint. Rustoleum paints are nice as well, but from what I have learned in researching a bit with others who used it on chassis parts, it is all in the prep. Some claim it does not hold up to dings well, and some swear by it. Myself, I believe it is probably in how it is mixed and applied, more than anything. The POR-15 does not have to be topcoated, but does react to UV light with changes in color if exposed. Not that your going to expose the underbelly of your truck though. Any rate, the POR-15 works best on rust, in my opinion. It isn't all that cheap, but what the hey.
Good luck in what you decide. I am sure there are other products out there that would work well too.

I would use an "anti-rust-paint." Here in Canada it's available at any automotive paint supplier. It will only last 2 years, then reapply. Less if you're off-roading and kicking up alot of dirt, or driving on alot of dirt-roads.

Now, if you're in the northern USA, where there's snow, and consequently salt usage, I would "undercoat" using an oil-based product. This can be done yourself using a compressor and a special undercoating gun (Princess Auto). Otherwise it's about $100 every year (actually every 2 years reapplication is good enough). This product displaces water and can be applied if the undercarriage is wet.
