'76 CJ-7 Axle Conversion??!!
 

Okay, first things first: Don't kill me for asking:)
Now... I want to do an axle conversion and need some advice on what to
swap (Dana 30 frt/AMC 20 Rr, 11" drums). I've done a lot of searching and
scrounging but can't find the right axles. A friend in a tranny shop
recommends 10/12 bolt Chevy's. Another guy want $800 for Dana 44's from a
79 Cherokee. Another guy who customs Jeeps wants to unload a 14 bolt rear
and 44 front for $600 (and $1500 in labor).
I've read everything from a 8.8 Ford rear to how Scout axles have
unacceptable drawbacks (for me at least). I either can't find the silver
bullet website or am overwhelmed with a million "Hey! I did this and don't
like this about it" hits.
Can you guys give me some solid advice on axle swaps? I don't mind if
it's wide since that'll help handling. Don't care if it's spring over or
under either since I live in the flatlands. I'd really like better braking,
though. I just don't want to go straight to a machinist off the bat.
P.S. tire size and gearing are a thought as well since I have a NV4500;
granny 1st is unuseably low right now and wiiiide gear ratio makes it drive
like a dump truck:)
Regards,
Jim

Re: '76 CJ-7 Axle Conversion??!!
 

Well, a lot depends on what you want to do.
1. How deep are your pockets, and how long are your arms?
2. What type of terrain do you intend to conquer?
3. Do you want lockers?
4. What size tires do you want to run?
5. What engine do you have?
6. What is your overall goal for this Jeep?

I ran my 89 Wrangler 2.5L on 33's with stock axles (Dana 30, Dana 35)
without any axle problems. Generally stock axles are OK up to 33" tires w/o
lockers. I've heard of people daring for 34's and 35's, but I probably
wouldn't go that far. Lock it up and wave goodbye.

Unless you want to lift your Jeep, keep it Spring-under. If you go
spring-over, you will get quite a bit of lift, on average about 6". If you
do want to lift it, during the axle swap is the time.

Anyhow, assuming you want lockers and/or tires above 33", any of the axles
you mentioned will be just fine, I would pick the one You can get the best
deal on. Remember that a full-size truck's axle will need to be narrowed to
fit under your Jeep properly, it'll look silly and probably be illegal
someway, somehow if you don't have it narrowed.

I suppose if you really wanted to pick one rear that would be the best bang
for the buck, it would be an 8.8" rear from a 96 and up Ford Explorer and
keep the Dana 30 front. The 8.8 is pretty close to the same width as your
front axle, has larger, stronger tubes and axle shafts, than your AMC 20 and
has factory rear disc brakes. I'm not sure if your CJ has the wide-track or
narrow-track axles, but someone who knows will likely chime in.

Re: '76 CJ-7 Axle Conversion??!!
 

I would say get an 8.8" rear w/disc brakes and lock it up. It should come
with 3.55, 3.73, or 4.10 gears.The stock D30 will be fine unlocked, and with
a locker in the back, you'll do really well. I think that setup with 4.10 or
4.56 gears would be optimal. Usually 33's couple with 4.56's, but withthe
350 and your transmission I don't know. What gears do you have now?

Re: '76 CJ-7 Axle Conversion??!!
 

I would say get an 8.8" rear w/disc brakes and lock it up. It should come
with 3.55, 3.73, or 4.10 gears.The stock D30 will be fine unlocked, and with
a locker in the back, you'll do really well. I think that setup with 4.10 or
4.56 gears would be optimal. Usually 33's couple with 4.56's, but withthe
350 and your transmission I don't know. What gears do you have now?
