So I just bought a 1990 f350 4x4 with a bad transmission (E4OD) for $600. It has a Dana 60 Kingpin front end and a Ford 10.25 limited slip rear with 4.10 gears. Any idea of how much the axles are worth?

 

As much as someone is willing to pay. I've seen axles go from $1-$500 or more, depending on what it is and the condition of what's inside.

 

exactly. supply and demand. i have seen kinpin 60's sell for $1200 with no brake hardware, and i have also seen them sell for $100 complete.
i paid $250 for the last one i got complete with springs plates, springs, shocks, driveshaft, and complete brakes system including lines.

 

There''s been a kingpin Dana 60 for sale for sometime for $1,500 on CL in my area.

I was looking for quite a while and most of the ones I found had the wrong gears or was to far away or sold before I had a chance to get to them.

Couple months ago I got one that was just listed. It was a ball joint with the rear axle, paid $1,200 for the both. He wouldn't sell them separate and they had dually adapters on them.

So as long as it's in good condition you can ask about anything you want for it. Also depends on how long you want to sit on it.

 

Same as said above. I've waited and waited and waited for a 1 ton axle to come around at a good price. They were either sold or hours away. Bought a jeep yj with the cash finally. Next day I met a fella who was going to scrap both his kingpin 60 and sterling rear. He dropped em off at my house instead.

Working on the 60 now to put into my 250. Everything is there.
