ford 9.75'' in a WJ?

alright, so I have been looking around for a while for an axle to start a long build on and swap into the back of the WJ. ultimately I will be doing both once i retire it from DD duty but I am starting with the rear. My goal is to ultimately run 36 or 37's. I was also looking to do something a little out of the box. I recently cam across a Ford 9.75'' out of an '01 F-150. It has disk brakes and the guy only wants $150 for it. it has 34 spline, 1.705'' shafts, a 9.75 ring diameter (same as a 60) and larger diameter tubes and higher torque rating. Its also 65'' wms to wms. I can get alloy shafts, an ARB and go as low as 5.13 gears. Basically the only down side I see is that its a c-clip. This will be my first swap and will take quite a while, mostly due to funds but I just wanted to get some input from more experienced guys and what they thought about it. Heard any positives or negatives? Also, I run clayton long arms so I would probably run his universal 4 link truss for the uppers....all opinions welcome

i have a semi float dana 60 in on of my jeeps. its a 35 spline c clip semi float axle. im running stock shafts and have the spider gears welded up running 40's. i have yet to break a shaft and i have beat the living piss out of it for many years.

you said its a 1.705" shaft but a 34 spline?? a 40 spline shaft is 1.708" and a 35 spline is generally 1.5". do the shafts neck down?

yeah, its 34 spline.....according to the specs ive found, its 1.705 for the '00 and up models...it does look like they neck down though because ive also seen where it compares the axle to a 60. it says "min shaft diameter on the 9.75 is 1.29 and the 60 is 1.36"

For $150, you really can't go wrong with those specs. Seems like it would take abuse from a 35-37" tire fairly well.

And with how popular the F150 is, I'm sure there is a pretty decent aftermarket for beefier shafts if needed.

the only real downside I had seen was the tube wall.....i think ill look into sleeving it. other than that i think it should handle 37's just fine esp with Yukon gears and shafts.

Yea, that was the only thing that really caught my eye. Tubes that are a little less than 3/16" might be a bit of concern. I would think if you made a decent, end-to-end truss it would be fine.

so once i get this thing broken down i'm going to stick with coils springs....im probably going to run Claytons truss for the upper control arms....anyone know of the best place for spring perches and shock mounts? Im thinking either use Claytons WJ brackets for the dana 60 (will have to grind them a little to fit the larger tubes on 9.75'') or maybe ballistic fab? any suggestions?

so at the end of the build what will be left of the $150 assembly? a housing with very thin wall tubing? with all the really cool 9" housings on the market for relatively cheap they tend to be the most economical part to upgrade. you have to give yourself a terminal point not to pass on any junkyard rebuild. its like taking a nice jeep and hacking it apart to the point where you have a jeep-shaped buggy. it really doesnt make sense. at that point youve ruined a good part-getting vehicle and replaced it with a mediocre buggy that would be much better if it was designed from the ground up as a buggy from the beginning. all im trying to say is if you plan to replace almost everything then just build from scratch.
