How about a Ford 9\"

for my CJ? Only thing I can see wrong with them is that the pinion is kind of low, but that's not a factor in my Jeep.

A local yard has one with the right R&P in a 1/2Ton 4X4 for $75.00. Spend another $100 with Moser to get the shafts shortened, and the rest I can do myself.

Apparently there are Detroits and ARBs for it. Only problem I can see so far is that the axel shafts might be necked down next to the splines, and impossible to shorten.

I can put the truck yoke on the Jeep driveshaft, or vice versa, so U-joints aren't a problem. Worst little problem I can think of is that the Jeep parking brake cables might not hook up, but it has Bendix drum brakes, similar to the CJ.

This site makes them sound pretty good:

Re: How about a Ford 9\"

You could have moser make some complete shafts for it if they can't be shortened.

Re: How about a Ford 9\"

the only downfall tha ti can see is the low pinion like you mentioned. Talk to Pontiac58 he has a ford 9 in his jeep, and is very happy with it.

Re: How about a Ford 9\"

Like stated above, you can get moser to make you exactly what you need. My only problems with 9's are that their case is really weak and ive seen 2 explode after landing hard on a rock. You can fix this by getting a strange nodular case. also, if your gonna get custom shafts anyways, you might as well go with atleast 33 splines. to go to 35 you definately need a new case.

Re: How about a Ford 9\"

It wouldn't be worth the expense to buy custom shafts or case. I'm just trying to replace the AMC 20 with something that won't spin a hub or bend a tube. Since neither has happened in almost 28 years, I obviously don't need something super strong.

So Pontiac, how do you like your 9"? And how tough was it to narrow?

Re: How about a Ford 9\"

You might want to look for a 9" out of an Early Bronco (66-77), they are big 5 bolt pattern, leaf spring, and should be approximately the right width. Plus the later ones (74 or so) have better spline counts and bearings.

Re: How about a Ford 9\"

Even a Bronco is going to be too wide I think. If I have to narrow one it doesn't make a difference how much. And the one I'm looking at is 5 on 5 1/2.

But it sure would be nice to know in advance which spline it has. Anyway to tell for sure without pulling an axle?

Just my opinion but that is exactly why you should get a one piece axle kit installed and wheel it for another 28 years. You have lower gears but I haven't broken mine so it's very unlikely you will break your AMC-20 running 31" tires.

May as well go to disk brakes on there while you are at it...

<u>Jeep CJ 5-7 & Scrambler Rear Disc Brake Kit</u>

or

<u>Rear Standard Disc Brake Kit</u>

I put in the SSB kit at the same time as Superior one piece axles, only take it apart for a re-lube a couple times a year. Have yet to have any type of problem.

You might think that rear disc aren't worth the cost and trouble. But:
1. Handle mud and muck with out damage and still stop you.
2. Much easier to work on and need work less often.
3. Never need to be adjusted.
4. Clean up with a pressure wash.
5. Allow the axle to be removed without opening the brake lines.

If you are an eBay junkie it might be possible to find a SSB Kit for less than half price. I did.

TSM will sell a complete kit or just the brackets. Get lucky at the salvage yard finding an old Caddie with new brakes and you have a low cost setup.
