shaving

[BIGoffroadXJ]

i was wondering if anyone knows how to shave an axle housing... my 9" could use a slimming

[BrettM]

it's slightly complicated with a cast housing like a D44 or D60, but with a stamped steel housing like a 9" or 8", it's a piece of cake. cut, measure, weld. weld about an inch at a time allowing time to cool and either post-heat or leave it to cool slowly in sand.

[BIGoffroadXJ]

when i do this, how close can i get to the carrier inside, and how do i deal with the center chunk bolting up?

[BrettM]

don't cut the mounting ring for the third, if you have a junk third lying around, I would weld it all up with that in place.

you can get as close as you want to the ring gear, just don't touch it and make sure your material won't get bent close enough to touch it. on my Toy 8" I used 1/4" plate and about 1/8" off the ring gear.

any pics?

[BrettM]

i don't have any pics of mine, it was very straight forward, but here is a thread of my favorite shave job: http://www.pirate4x4.com/forum/showthread.php?t=353293

I'll take some pics of my shaved 9 tomorrow and post 'em up for you.

while were on the topic of 9" rears, does anyone know, if i get a HP center chunk, will it bolt up to my LP housing?

Yes, both Currie and hi9 will bolt right in. If your getting a new one go with hi9. Much stronger.

[BIGoffroadXJ]

did anything come stock with a HP, being 17, im poor... so im trying to find something i can swap my gears in and bolt up for cheap. I live in PA redneck capital of the noth east so i should be able to find one if its off of an earlier ford muscle car/POS. Right now im running a LP out of a 67 bronco. How much would it cost for an aftermarket center chunk w/o gears, im putting a $15 minispool compliments of ebay into mine soon, and i might as well move the gears to a different carrier while im at it.

[David Taylor]

No hp in a stock application. If your tight on funds don't even think about a hp
center.

[BIGoffroadXJ]

No hp in a stock application.

Are you sure? i am almost positive that my friends 70' mustang mach1 has a HP 9"... of course i could be wrong, its been a long time since ive been underneath it.

[magoo117]

No,no such thing as a Ford issue high pinion 9.My Currie Hi 9 is for sale.I have somebody who is going to buy it,if that falls through I'll let you know.It is a 31 spline,4.88 gears and a full spool.I'm thinking around $700-.Let me know if your interested,I'm in NJ,so I'm not that far away.

lets not confuse a currie hp and a true hi9. Big diferance.

[magoo117]

No,your right,thats why I said CURRIE.They are both hi pinion 9's.Right,Currie is technically an 8.8 but thats a whole different thread.Currie is coming out of mine and True Hi is going in.

[BrettM]

magoo, it looks like you shaved the 9 at an angle not parallel to the ground, why? I shaved my Toy8" with a plate parallel to the ground and it slides over stuff great and affords the most possible clearance.

on another note, what did you change the wheelbase too? have you run the numbers on your 4 link?

[SeanP]

I don't know why people insist on Hi-pinion 9"s. Sure, in a SWB wrangler where pinion angle is crucial, but XJ's are fine with low pinion. Whenever I have a clearance issue, I just keep hammer down until the rock grinds away :)

I guess the pictures are not showing it right because it does sit parallel to the ground.The MJ is sitting kinda tall in the pic also because there is nothing on it or in it.The wheelbase we set the same as my Chero because that worked well.Yes,Wheley Ent. set up and installed the rear suspension.They are our east coast competition buggy builder. www.whaleyent.com

I beg to differ,I had a low pinion 9 in it before the Currie.I killed driveshafts dragging over rocks way too much.I've still crunched a couple with the Currie,part of the game I guess but it still better to have them tucked up out of the way.

The difference between hi and low pinion is what, 4 inches or so? I don't think that it's going to make that much of a difference in whether you crunch your driveline or not. At least not enough to pay TruHi9 the money they want for the third, carrier and R&P.

I know first hand,like I said it made a big difference between the stock lo and the Currie hi.Bigger tires require the use of the True Hi 9.I was running 38's with the Currie,and that was pushing the limits.Now I will be using 39.5's on the MJ so I need the extra strength of the True Hi 9.

Are we talking the benefits of the clearance or strength in a high pinion9? Clearance: The 4" or so at the pinion probably isn;t going to be the difference between a twisted driveline or not a twisted driveline. If you manage to high center yourself on a rock on your driveline I don't think it matters. Again, driveline angles on a SWB rig, and the corresponding weakness of the u-joint because of steep angles are why the wrangler folks want HP.
Strength: Yes, I have heard that the 8.8 R&P in the Currie HP is a weak point. I have a Strange Nodular 3rd with the 3.25" carrier bearings and 35 spline dutchman shafts (lifetime guarantee). I am not at all concerned about the strength of my LP center section. In face, my same set up is put behind 1000+HP top fuel dragsters, albeit with less traction available than a 38 SX on granite.

I'm gonna have to disagree here. Though it's mostly due to my 115" wheelbase, I banged/twisted 2 driveshafts last summer on the Rubicon and Fordyce. Both times it was in the back third of the driveshaft which would be 3-4 inches higher with a Hi9 and would have easily cleared in those situations. I also noticed I have some new shiny striping on my driveshaft from Hell Hole on saturday, again on the back third.

I would love a Hi9, but certainly am not gonna shell out 2 grand when my I have under $300 into a locked geared Toy axle that is basically bulletproof on 35s.

I'm confused. How can you not see the huge benefit to having your drive shaft
4.5" higher up. The difference is night and day. When you look at my junk from the side you can hardly see the drive shaft it's so high up. I see this as only being a good thing.

I am talking about clearance.4" is a huge amount.To get your drive shaft 4" more clearance without a hi pinion it would take 4" more of lift or tires 8" taller,thats alot I think.Strength issues for me are why I'm switching from the 31 spline Currie to the 35 spline True Hi.

Ditto!

Some of us just have to have the best.......others mostly web wheel.

:D

There's plenty of times that I've barely scrapped my rear yoke, if it was low pinion I would have been in trouble. This is especially true since my driving style has changed to first give it some more gas, then back up if it doesn't go. If I had a low pinion rear end, I'd be backing up more rather than risking hitting the rear yoke or driveline......just a little more piece of mind.

[BIGWOODY]

The hi9 seems to be the way to go, but $2000 is a little pricey. I took my $2k and bought an Atlas, then some 39" krawlers . I also have a strange nodular 3rd with 35 spline spool and chromo shafts. I have nice custom drive shafts that I have pivoted my MJ on and haven't broken one in 5 years. I carry an extra one and 2 extra yokes. I have broken a yoke and it took all of 10 minutes to repair...just not worth $2k to me.

so where do you get an atlas and 39" Krawlers for 2 grand?

[BIGWOODY]

Just the Atlas...the 39" krawlers required some more cash as well as the Walker Evans beadlocks. The Hi-9 went way down on the priority list.
My point was I got more use out of other $2k mods...

[magoo117]

My Atlas cost about 2000-,does that mean I was supposed to get a free set of 39 Krawlers with it?
