Will a 10.25" Sterling axle from a mid 90's F350 single wheel truck replace the D60 rear axle in my '79 F250 with out a ton of work? I have read both yes and no. Has any one done this swap? Can the wheel studs be changed from 9/16" to 1/2"? If no, can the studs on my '79 D60 front be changed to 9/16" ? The reason for the question is I have found a Sterling with the right gear ratio (3.55) to replace the 4.10 rear I now have. I have a set of 3.55's for the front axle.

The 4.10's have my Cummins wound up tighter than a cheep gutar

 

I am answering the stud question in a round about way. From my experience, as long as the wheel will fit over the 9/16" stud, the acorn nuts for the 9/16" lug will fit just fine and hold the wheel properly that you are using on the 1/2" stud wheels.

I start to tighten from the top and make sure everything is centered before I torque to 140 pounds.

 

I would have the front D60 machined to accept the 9/16 studs.

 

i did mine without machining.....sorry dont have the part #'s, all i did was get the specs on the factory 1/2" studs where they press in then matched them to some long 9/16"
