Difference between AMC 20 and Dana30
Hey,
If anyone remebers I just dropped the driveshaft out of my '85 CJ7,
turns out I need to replace the rear-end yoke too.
Searching around it seems there are a few options u-bot style or
strap. Seems like the consensus is U-bolt. My question is:
Is there a difference between the AMC 20 and Dana 30 yokes?
>From what I've read they used both in the '85 CJ7's. In pictures they
look alike. The reason I ask is I can't find one locally and will
probably just buy online and want to buy right the first time...
Thanks for the help and sorry if I sound like an idiot, I am new to
the Jeep, but insist on doing everything myself...

I an not sure about the outside diameter in seal area and such but the
AMC 20 and D30 have same pinion diameter shaft and spline count. I
would suggest though that if you are having issues with drive shaft
and yoke staying together that you should consider deeper axle gears
because you are reaching the limits of drive shaft loading and it is
kinda a "fuse" of sorts for drive line.

Re: Difference between AMC 20 and Dana30
Dana 35 on the rear. Your CJ7 probably has the AMC20. "Want to buy
right the first time"...you don't want much, do you? The rear end
covers are definitely different shapes. Browse around on the Jeep tech
sites until you find a good picture. The AMC20 cover is more oval,
flatter as I remember it.
Replacing that pinion yoke is not a job for a beginner. You need the
proper puller, not a bmfh, to get the old one off. You need to torque
the new one just so, or you will have pinion bearing and ring and pinion
problems down the road. You really want the special tool/wrench to hold
the yoke too. Don't rely on the emergency brake and wheel chocks for
this. Maybe a big pipe wrench will serve for this, if it doesn't slip
while you are tightening the nut. The nut too is a one time locking
throwaway nut. Some high strength thread locker might help here, but
get a new pinion nut. This looks like a simple job, but there are so
many ways to screw it up.
Hope this helps some.
Cheers,
Earle

Re: Difference between AMC 20 and Dana30
You would be asking for a 1310 yoke for an AMC 20 rear end, or model 20
some places call it.
