Re: '76 CJ-7 Axle Conversion??!!
 

Whoof! I've got 4.10's in the rear (LockRite Locker and one-pc forged
axles). When you combine the 4.10 with the 5.61 granny 1st, the tranny's
basically a 4 speed where I use second as first and so on and the 5th
overdrive gear's a fairly low fourth.

Re: '76 CJ-7 Axle Conversion??!!
 

It's not often that a Jeeper wants to re-gear to a numerically lower
(higher) ratio, but I think you can gear the D30 to 3.73, which is what (I
think) a lot of 8.8's have. You can also look for an XJ dana 44, which
should have the 3.73's and if the axle shaft's break, the wheels will stay
on.

Out of curiousity, why do you need to upgrade the AMC 20? I assume is an
issue of reliability / breakage?

Re: '76 CJ-7 Axle Conversion??!!
 

Braking and handling are pretty much the desired effect (wider w/better
brakes). The AMC20's built stout and I should be happy with as much as I've
put into it. Still, I'm not and the 4.10's are just too much. The front
Dana30's are shot enough to be swapped and that's where it all started. If
I went to larger tires, I'd have to lift more than the current 4" and the
body roll's a bit much for a daily driver as it is.
