: Shaving a 9" for 1& 1/8" better clearance
Aggro 08-20-2002, 05:31 AM A ford nine doesn't have bad clearance if you run it pinion parralel to ground. That gives you a rather low pinion entrance to the diff though. The more you rotate the pinion up (as most wheelers do) the more ground clearance you lose. This is how to fix that problem. I cut 1.25" off the bottom and plated the void with 1/4" inset into the cut on the front of the axle and on top of the cut at the rear for an overall gain of roughly 1.125" clearance under the diff- the same as going from 38's to 40's.
Marking for the cut:
Aggro 08-20-2002, 05:32 AM Making the cut:
Aggro 08-20-2002, 05:33 AM Clearance to gears when everything was said and done = .25"

rkcrawl 08-20-2002, 05:41 AM Very cool. :D I will have to remember this one, and think Currie charges $150 for that. :rolleyes:

Nice work -- got a pic of inside the housing, before you installed the third member?
I'm curious about the three-holed chunk of metal, here. Was this just used for fixturing purposes, or does it tie into an internal brace?

I can get a pic of the inside if you'd like. I won't re-install the diff for a couple more days. The verticle 3 holed piece is a gussett to resist denting from the bottom of the diff and it ties into the front and rear of the housing. It is parallel to and right next to the ring gear.

In that case, nice 'speed holes,' ya ricer! :flipoff2:
Seriously, nice work. Heckuvalot easier working with stamped steel than big chunks oh Dana-cast, ain't it? :D

welndmn 08-20-2002, 02:07 PM cool, I have been meaning to do this for over a year, i just don;t want to pull the diff out.
PS still looking for a junk 3rd member so i can do this
Oxjockey 08-20-2002, 02:29 PM Nice! :beer:

A guy I know has Currie 9" axles F/R that are shaved by Currie.
He was told by Currie not to run them long distances on the street
because there's less gearlube in the pumpkin to disapiate heat
and the bearings could over heat.
Good job.
But for 1/4" gain.... I don't think I would waste my time.

Hey newbie pull your head out and read the post before you reply, he said he gained 1.125" and 1 more thing
:flipoff2: welcome newbie:flipoff2:
Whoa! I guess I fucked up!
Wilson 08-20-2002, 06:50 PM Damn, I didn't even think of that when my housing was sitting in my shop for 3 months while I was finishing the rest of the truck.
Jason R 08-20-2002, 09:46 PM Nice job, but I don't think its worth the effort. Tell us how everything works out. :D

THe NOOB isnt that far off the actual gain is going to be close to that..
NOtice the gear housing is not going to drop
Notice that his cut is going up hill to match the ring gear
Notice the actual distance between the ring and the housing @ 1/4 inch...
Now he did remove the lip and make the bottom smoother overall and easier to slide over rocks however REAL Gain from the ground up is not 1 1/4 inch...
Well, you might be right...It all depends on what the pinion angle is set at. If it was 0 then there would be no gain. But as the pinion is tilted upword the shaved part comes into play.

Dude! Lay down the crack pipe NOW. If you don't understand you shouldn't let this type of thing come out of your brain. My pinion angle is set to 25*, and and I had better than 1.25" of housing under the ring gear at that pinion angle. I removed all this material and added 1/4" plate to fill the void, for an actual gain of roughly 1.125". Like I said in the original post, The more you rotate the pinion up (as most wheelers do) the more ground clearance you lose. If the housing was parallel to ground, I would have gained NOTHING, but since the housing is rotated I truely gained ground clearance back that was lost due to rotating the housing. Nearly any axle housing you rotate up you WILL lose ground clearance, with one exception being the ultra gimmick tera50 "with crd" (!)

OOOOH! I think dem's fightin' werds. :flipoff2:

the more you rotate the pinion op the more fluid you have to add inorder to have fluid come out of the fill spout.... so you gain any lost fluid back IMO
SWEET WORK

Kind of, but where the oil goes is in the Tubes and it tends to blow out the axle seals
^^^ never heard that one ^^^ :confused:
Goose 11-15-2002, 02:16 PM Hey Aggro,
Do you have any update on this since you finished?
Any problems that you ran into since you did the High Clearance.
(The Rockslut) said it frickin look tight underneath your rig and work out good on the trail.
Just curious
Do you have any pics installed in your rig?
Thanks!
:D

Sweet job - Deja Vu! - I just did mine about 6 months ago - I ended up with more ground clearence than the D35 that came out :eek: The 9" is really fun to work with...

AAAA housing rotation.... I have to keep mine perfectly level for 6X6 this is of no benefit to me.... I didnt even think of housing rotoation...;)
Good try at a cover up :rolleyes:
Anyways good job with the 9" got any pics of it mounted under the rig?
bignissan 11-15-2002, 06:19 PM very nice work...i think i may tackle that when i pull my axle to weld in a drain plug...
greg
TNToy 11-15-2002, 06:52 PM I would put some thought into it before i installed a drain plug. Toy housings are similar to 9" ones - and they come with factory drain plugs.
I can't wait to cut the bottom of the housings to get rid of that stupid plug. It ALWAYS leaks after it gets tagged by a rock or two on the trail, and it likes to snag on things. This is a very low-pro drain plug, with a guard around it.
I would do what the toyota guys do. Replace the bottom two studs with bolts to use them as drain plugs. IIRC the 9" studs are pressed into the housing like wheel studs, so you'd have to pull the 3rd, pop out the bottom two studs, and simply tap the holes for whatever size bolt you choose.

Yeah, go ahead and get back to me in a couple more days! :flipoff2:

Moab Austin 01-10-2006, 09:42 AM which Daniel is this guy?
also I thought you werent suppose to run any currie axle very far at any speed?

Davethorik 01-10-2006, 10:12 AM Well, since he mentioned a 6x6 and his dumbass post is deleted for no apparent reason.... :flipoff2:
