Will '93 D250 dually rear axle fit under '86 W350 cab and chassis dually?

[MRMiller0]

So I spun and inner wheel bearing on my '86 W350 cab and chassis dually with a dana 70 and moved a bunch of metal from the bottom of the spindle to the top. I have not been able to find this exact axle anywhere.

I did find a rear axle out of a 1993 D250 dually and I was wondering if it would bolt in?

I have 4.56 gears in my axle and the axle out of the '93 has 3.54. My plan is to swap my gears into the '93 axle if it will bolt in.

Thoughts? Any advise is welcome.
Thank you

Never heard of a 3/4 ton with a dually rear axle….

The complete rear end will 'bolt in' no matter what it is between those dodges. there are different widths. The dana model (i.e. 60 or 70) will decide if you can swap ring/pinion/carrier.

Oh ok, thats what I was told it was and I'm new enough to dodge I didn't know the difference.
Thank you for the info.

Good to know. So just to make sure I understand correctly, A Cab and Chassis dually will just be narrower overall than a regular dually axle but spring mounts are same? And as long as both are either Dana 60 or 70 the gearing will interchange?
Thank you

All the Dodge dana 60 rears i have found are singles. 70's can be either single or dual - 5/8" studs on a dual.
