Question Got a Question Scary Thought

ok i found a 89 Ford ext cab diesel. instead of having 6 wheels it has 10 wheels on it the very back axle is a drag axle is all, has a flatbed on it, stacks with mufflers yuck, 5 spd, the motor everything looks like a 7.3 but valve covers say 6.9 diesel on them, didnt look to see what the block said though, but its got new alternator, vacuum pump, water pump, ac, power steering, batteries, injectors, glowplugs, alot of new stuff on it. but was wondering if the drag axle could be somehow connected into the other one so it wouldnt be a drag axle if it could be id buy this pickup in a heart beat but if the drag axle cant then i dont want no part of it all it would do is get me stuck the places i go lol . any info regarding this would be nice. thanks

The 7.3 and 6.9 are externally identical. so it could be a 6.9 swapped in. yes there are ways of making it a live tandem, but you will probally have to swap out the rear end for it too work.

The best thing to do if you like the truck is remove the drag axle, it is only extra weight for nothing.

The drag is to be able to haul more weight, remain "legal" and support the weight. If the preice is satisfactory, and you don't need the capacity, ditch the axle and use the truck as you wish. In a light duty it would be troublesome to get both axles live. On the heavies the driveshaft goesinto the front axle, and then there is a shaft that comes out the back side of the axle to the other axle, I personally do not know of any available with the pass through shafts, so it would either require a heavier axle, or somehow to tie the drive shaft into another drive shaft to the rear. I really don't see the feasability in it. My uncle has a grain truck, and it has the dummy axle on it, and single axle driver. It does well for his needs and keeps the weight legal on ok on the chassis.

I guess it also depends on where you live, here they just look at it as more weight thus lowering the amount you can leagally carry. Then if you up your GVW to allow for the extra weight (flat deck and or the axel) they will make you go for yearly inspections just the same as an F-450.

k yall i live in texas so yearly inspection aint no big deal as for the extra weight dont matter to me wont be using it to pull much just for looks and get back and forth to the drilling rig and so on. But DT where and how much would one of them axles cost or the conversion cost , and how much trouble are we talking about doing to this too. any help would be nice.

You are looking at a good bit of work, and more dollars than the truck will cost you. Axles big enough to have a live tandem will have at least 10.00 - 20 or bigger tires on it and air brakes. If you have a military salvage yard near you, you may find something there. But those old military trucks that had hydraulic brakes had about 6 to 1 for an axle ratio.
