    I've posted over 100 responses to your questions in my first month here. Now I need some help.

    I just bought a 1980 Ford F250 a V-box salt spreader in place of the bed in back, on a single axel. I'm wondering if I should replace the single axel with a dually because of the weight it will have to carry. It was used by a school the last 14 years so it never had to run more than around their parking lot. They even had a little 3 gallon gas tank to replace the regular tank when they took out the bed. We'll be using it to go from job to job and alreasdy bought a bigger gas tank.

    The tires are dry rotted and need to be replaced. My friend told me 8 ply 16.5" tires will hold 2700# each (5400# total) and should be enough to carry the spreader filled with salt. I think it's a 1 yard hopper.

    Would you guys recommend putting a dual axel on there and getting 6 new tires or just keeping it as is with the 4 tires?

    The Ford, 4.10 and 5.13 rear axels are set up for dual rears as well as single. At least that is how they are set up on all of my trucks. All you have to do is buy two extra rims, and the extended studs.

    Snow Pro,

    What is the rating of the current rear axle? I am not sure what a 1 yard spreader weighs fully loaded, maybe some one else does.

    FYI.. the rear tires on my Ram must be rated for over 3K lbs each, since the rear GAWR is 6K+lbs. They are 16" Michelins.

    I would find out how much the spreader weighs when full, then make my decision, based on the rear GAWR.

    Load range E 16 inch tires are good for 3042 each when properly inflated. There is a 16 inch F rating used on the new Fords which is how they can milk 9900 lb GVW out of a SRW truck.

    Those 1 yard spreaders are designed for Ranger and S 10 type trucks so I dont see the need for adding duals, fender flares, then changing the front hubs to fit the dual rims unless you carry 2 spares, etc.

    Geoff, do those Fords run the offset wheels in the SRW configuration? If not you would need 4 wheels to accomodate duals.

    Alan, your right on that one, you would need to buy four wheels. The point I was trying to make, was you don't need a new axle, Just extended studs, and like Alan said, 4 off set wheels.

    Does anyone know if there some place I can find out what the rear axel ratio is. Is it coded into the VIN? Can you figure it out by looking at it somehow?

    Thanx guys!

    is it a full floating rear axle?meaning the wheel bearing carries the load,or is it a semifloating axle where the axle shaft itself carries the load. full floater is stronger! you can tell a full floater by looking at the rear wheel, is there a big round hub sticking thru the rim? if so you have a full floater.
    axle ratio can be identified by a tag bolted to the rear axle cover,but it is probably rusted off by now.there are other ways to find out but my guess is they are either 3.73 or 4.10 gears. both will suit you fine for plowing and or salting. if you really want to find out the ratio let me know and i'll tell you how.

    This is what DYNAPLOW is talking about. This is a GM axle, but it' a "fullfloater". Looks almost the same as the Dana 60. Not sure what fullfloater Ford uses, but if the axle you have is a fullfloater, the hub will look very similar to this one.

    Thanks Chuck for pointing that out, ford has used DANA axles
    as well as their own axle they call the 10.25. meaning 10.25" ring gear.
    further more i agree with you that cv joints and ifs suspensions in pickup trucks are not heavy duty.
    leaf springs for me!
