Hey guys just put a new mag hytec diff cover on and now I realize how rusty my rear axle is due to Wisconsin rust! I was wondering if where i could buy a sandblaster to blast and reprint my axle? arty018:Suggestions please..thank you in advance! Also do I just use a spray paint with primer?
i just spray painted over the rust on my axle and it looks fine as long as your not crawling up under it, if your looking for a cheap blaster though you can get one at harbor freight or northern tool

I would recommend just knocking of the big chunks with a wire wheel and painting it.
Sandblasting while it's assembled runs the risk of getting sand into the e-brake assemly, etc.
Not good. or anywhere else for that matter.
They also make a product you can get at most paint shops that sprays on with a windex bottle, chemically reacts with the rust and stops further corrosion. Just wire wheel it down, spray it on and then follow with paint
The rust battle up here is a twice a year deal I feel. Spring clean up and then fall protection. Like they said, knock off whatever you can. Clean with something like brake cleaner. Then nuetralize the rust. Don't go hog wild with the nuetralizer cause some versions are bad for the remaining paint. Then paint with a thick paint like rustoleum enamel or POR 15. Then in fall hit it hard with Fluid Film. Rinse and repeat next year. Usually I can get 2-3 years out of an area before it needs more paint. Recently I switched to gloss finish paint because I think it helps debris get washed off easier.
Using this method my frame and suspension are rust free. I keep the body rust free by washing twice a week during winter and fluid film in fall. In spring I go crazy with the garden hose in all areas where normal line washing can't reach.
Fluid film or some other similar corrosion inhibitor is a major part of the successfulness of any rust prevention method. This year I'm stepping it up and buying 2 gallons of it and a sprayer. I plan to apply it some time in early October.
Where in Wisco? This year I noticed a lot more sand usage than previous. The bedsides have a solid layer of sand clinging to them that need to be blasted off. Id rather sand than salt so I'm alright with that.
thanks for the reply man! And I am around the small town of Gilman.. It is north of Thorp wi. Lots of our roads are gravel so the truck gets a lot of rocks thrown at it. I will do what you suggested and soon I will have a new looking axle.. Every time I come home from anywhere I wash my truck with hot water. Then on the weekends I use the pressure washer underneath. My truck turns heads during the winter time because it is the cleanest truck around!
walnut shell blasing media can be used. (it's ground up shells, you can't use whole "walnut shells")
$1-2 per pound depending on where you buy it.
Walnut shells are normally used for soft metals as it's not as aggressive as sand (easier on the parts).
I only use them in a blasting cabinet where they can be "recycled". Depending on how much rust you have I could see it taking 50+ pounds to do the rear diff.
IMO just wire wheel it and paint it. It's gonna come back anyway. Never saw a diff rust through.
if you could take axle off and put in a blaster id say blast it! however, I think an angle grinder and a wire wheel is the best bet. you do have some brake lines and such I wouldn't wanna get near with a blaster, especially if they are already weakened by rust, so youd have to get next to em with an angle grinder anyhow.
Take a pic so we can see how bad it is. I don't think sandblasting is needed. POR is some mean stuff. It etches itself to the base and will seal up the rust quite well.
Clean it, neutralize then seal it up. U still have the sticker so it's not bad. I just went in and cleaned er up real good to weld the tubes to the pumpkin. Mine was only a bit better than ur pic.
Welcome wisco brotherin withthe rust battle fluid film is where its at. Broaner has me hooked on the stuff wish I would have bought a case of it.
Also for the axle agreed wire brush and gloss paint seem to work wonders . make sure to rinse your doors out and rockers a few times during the winter. Personally I wash mine with a hose(hot water hookup in garage) every time I drive it in the snow especially over the wells in the box
Yup. Your better off to knock off the bulk of the loose rust, degrease, and seal/paint.
It's a whole nother big project if you want to sand blast and do it right so it lasts.
Plus alot of people just don't have enough air supply to run a sandblaster. At least not a pressure pot.
If your project was to have a show truck. Then a differnt story.
I have blasted white a couple trailer frames and snowplows. There is alot of expense and time doing it right. My little 110# pressure pot takes alot of air. At 125 PSI at the pot my 2 stage 80 gallon compressor keeps up without a problem. But a single stage I'm pretty sure would never keep up.
Like that sled too. Looks just like my wifes 02 700 mxz-x.
I have a 30# pot and a 60 gallon single stage would keep up for only 5 minutes at a time. Then I had to give it a recharge break. Now I also have a 2 stage 80 gallon and I agree, its no prob.
Just a little highjack here rather than starting a new post, when you guys paint your frames (undercoat) do you do the underside of the bed and cab as well? Or just the frame/springs/axles?
Undersize of the cab is a good idea. I plan to line x the bottom side of the bed if I ever pull it off.
Once its well painted fluid film helps seal it all up for all but the last 2 months of winter. If you washed rarely the fluid film would stay on longer. I wash at least once a week and the fluid film gets slowly removed.
