looking at finding a 9 inch sometime in the near future and wondering what vehicles they came on and what ones are the more superb! tia fellas
 
For a guy with a tight budget to build his rig...... a 9" isn't a very budget minded axle.

-I dont' know for sure, but I believe most will be wider than XJ axles (the early Broncos being the exception - and hard to find). You gonna go "full width" in the rear and keep the D30 up front? :looney:
-The lug pattern will be 5 on 5.5.
-Gears and parts aren't any cheaper than the rest.
-Most will be 4:10 gears which can be a good thing - unless you're going with 33's or bigger.
-The diff housing isn't much different in size than the rock catcher 8.25 (especially with tires 32" and smaller)
-You'll have to cut off and move the leaf spring mounts.
 
Like Troy said, a full width mid-'70s and later 1/2 ton trucks.

There are some under the sedans, but they are not likely to be as strong. Another caveat: The narrower axles are just as likely to be an 8-inch. Yep, Ford made an 8-inch, looks just like a nine-inch. The giveaway is wether or not you can get a socket on the bottom two nuts that hold the third member in place. I don't know when production stopped on the 8-inch.

Yo can break a lot of D-35s for what it takes to set up a non-stock axle.
 
im just doin a little thinking for the future troy planin on grabbin some axles and builing them up and then tossing them under the rig i may just go with the 8.8 ?

Unless you find a car one or an EB one they are full width yes, there are a few big lincolns that had 5x4.5" in the "right" width, but they will have lower (numerically) gears than 3.50

-Gears and parts aren't any cheaper than the rest.

Actually they are often much cheaper since they are so popular with the hot rod crowd.

-Most will be 4:10 gears which can be a good thing - unless you're going with 33's or bigger.

Actually, most are 3.50 (from f-150's and supercabs even on the 2wd ones)

-The diff housing isn't much different in size than the rock catcher 8.25 (especially with tires 32" and smaller)

Yup, the pinion is pretty low, but that offset adds significantly to the strength of the gears

-You'll have to cut off and move the leaf spring mounts.

To find some more accurate info
I'd start by reading this
http://www.maliburacing.com/ford_9_inch/ford_nine_inch.htm
it's a great resource for 9" info
and has tons of widths and gear ratios and third member tech

good luck :D the 9 is a great axle and it's used by a large portion of the XRRA field and all of NASCAR, you can get 35 and 40 spline shafts that fit in the stock housing 9 with an aftermarket third member)
 
So, what would one be worth? I know a guy parting out a '91 with D44/F9", 4.10s i believe. Transfer case blew up and he's tired of screwing with jeeps. Axles were sold, but I don't think the buyer has come thru yet. Motor and tranny out of a '98 too. If anyone's interested lmk and I can check status. Don't know what he wants for 'em.
Big ole rack lights too, 4 front and 2 rear iirc.

GO WITH AN 8.8!!!! They are much more common making them cheaper. That compounded with the fact that the hot rod community, then the off road community saw the benefits of the 8.8 are makign them harder to find and more expensive. An 8.8 is the proper width for an XJ, and nearly as strong stock for stock as a 9". If you begin to modify, the sky is the limit. The aftermarket is making all sorts for goodies for the 8.8. (c-clip eliminators, lockers, axle shafts) The 8.8 is a dime a dozen as so many vehicles have them.

A few things to consider when looking into a 8.8. Ford began using these on their full size trucks int he 80s. Stay away from these. they are an "off center" axle. when you install these you must cut the drivers side tube down to size. Once you do that they are still a 28 spline axle. Short of it is to stay away from all full width 8.8s. The 8.8 was avalaible in the Explorer and Ranger (and Mazda versions). There are a few minor and yet major differences in these axles. Rangers are a SOA (Spring Over Axle)while the Exploreres are a SUA (Spring Under Axle). Explorers are a 31 spline, while the Rangers had a 28 spline. Rangers with the FX4 and FX4 Level II package have 31 spline axles, 4.10 gears and limited slip differentials. Rangers have rear drum brakes only while Explorers have discs in some. Explorer sports will ALL have 4.10 limited slip gears. These are preferential based on the fact that they usually are not too abused. The most common gear set is a 3.73 followed by the 3.55. They run from a 3.27 all the way to 4.56, however both of these are VERY difficult to find. A semi common gear set is a 4.10.


Hope this helps some!!!
 
My only advise for you is learn to weld, stay single, and take your time and do it right.

It helps to keep a piggy bank for that "deal of a lifetime" when it falls out of the sky...and a place to store the collection while you plan pulling it all together.

I almost feel bad for JAWA paying full price for his. He still made out like a bandit, got all NEW brakes. I got there before anyone else could molest the poor thang. He'd be paying extra for the brake parts if we waited.
