Quick question about Ford 9\"

I've got a chance to trade some wheels for the rear axle out of an 81 Ford Bronco. That should have the 9" rear right? I haven't see it yet, but the Bronco has a siezed 302 w/4spd. I've asked my Dad to go look at it since it's only a few miles from him (and 170 from me). If it is a 9", the housing doesn't change based on gears does it? Isn't is just the carrier that changes for lower or higher gears (i.e 3.55 and numerically lower are one carrier, and 3.73 and numerically up are a different carrier). I don't know much about axles/carriers/gears, but the 9" seemed like a good candidate for upgrading my current offset D44 (w/19 spline axles). I want to run 58" WMS axles w/ 36" tires so that I can widen my stance for a little more stability. The 9" should hold up to 36's. TIA... Bret

Re: Quick question about Ford 9\"

The 9" uses the same carrier for all ratios. When you take the 3rd member out you'll see you can adjust the carrier so the ring contacts the pinion properly. The EB 9" fits great on my CJ; it's a little wider (something like 6", 3" per side) than the stock narrow-track AMC 20. I would go out and measure it for you, but it's frosty cold out. Sorry. I think, but I'm not sure, that the big Bronco 9" that you're looking at is wider than that, like F150 width. Measure to make sure.

Re: Quick question about Ford 9\"

Yes, the later model bronco's ('78 up) have axles that are wider than 58". They would make a good canadate to have narrowed however, and I am looking at doing the same. They have the same carrier for all gears, but the late model 9's have 31 spline shafts, unlike the EB's which only have 28's. If you want to run an ARB locker in the rear, they only come in 31 spline.

Re: Quick question about Ford 9\"

I think the later Bronco's were 62" or 65" wide, but I'm not sure. I've been diggin around on the net trying to find more info on them. Some sources are saying that the axle tubes are thicker on the post '78 9" axle. I do remember reading that the older (late 60's) 9" tubes were fairly thin. I used to have this stuff bookmarked, but I'll be dang'd if I can find thise links [img]images/graemlins/mad.gif[/img] I think I'm going to move forward with this trade. Too bad it has that TTB front axle, since the whole Bronco can be had for $200.... The rear axle's the only thing I want from it. Anyone convert a 9" for front axle use? I'm sure I could find another 9" fairly cheap... I see that Currie has them (but dat's a whole lot of coin [img]images/graemlins/shocked.gif[/img] [img]images/graemlins/tongue.gif[/img])... Hmmm, I wonder how hard it would be... [img]images/graemlins/smirk.gif[/img] Thanks for the info [img]images/graemlins/grin.gif[/img] Bret
