I want to see your pictures of ford 9" that you have in your jeeps. I am also open to ideas of what you think you would have done different in your 9" build up. So bring the pics on.

muhaha $5 and you can see all the pics you want of 9"!!


seriously go with a hp housing and at least 31 spline shafts (aftermarket) those stock ones suck. The 9 is a great axle when set up right

i just got done swapping in a 9" in my yj and it worked out perfect, it's not a hp and i didn't have a prob at all. also the 31 spline is a great upgrade, slap in spool and call it done. make sure you've got a sye,and a cv drive shaft from jess and no prob's at all.

I just did a 9" swap in the rear. I went with a standard pinion because Currie does not recommend the high pinion 9" for over 33" or so. I also did not go with the full floating option I was planning on because Currie also recommended against it for leakage and strength. (BTW - I am running 33's now and I will do 35''s or 36's later this year with ARB). I did not want to spend the $$ either for discs. Also, rear discs causes master cylinder and prop valve complications.


If I had it to do again, only thing I would do different is an aluminum carrier (a-la 4wd article) to save TONS of weight. You give up very little strength and save like 50-100 lbs. That is worth it.

Also, I might have upgraded the yoke size, but I didn't have the $$ leftover to modify the driveshaft, AND I wanted to carry only 1 replacement U joint, not 2 types. I guess they are small......

I say the best part of a 9" build up is throwing it away and building a 60:flipoff2:

Sounds like currie took you on a ride full of B.S. Full floaters leaking? Not stronger??? Are you crazy?

So you payed curry to build you a stock 9"? :rainbow:

We went to http://www.sunrayengineering.com/
The reason for this is we are in the UK and the junkyards don't have the goodies you do!!!!
They are being fitted to a Challenge prepared Cj7 360, spring over 36x12.50x15 Super swampers 4.88/ARB

The reasons for the hybrid 9inch is simple the weight compared to the D60/D44,the better ground clearance compared to a D44 ,the Sunray 1550 front and rear axles ARE a lot stronger than proroc 60 and I can have "behind the pumpkin tie rod" all highsteer,all shafts are 35 spline
I look forward to trying to break them!!!

Not to impugn your judgement, but let me get this straight: so you are unwilling to plumb a prop valve into your junk, and maybe pull an o-ring or two in your M/C, which will let you run the (arguably more effective) disks and save like 50 lbs right there or something, but you are thinking that the costs and drawbacks of an AL housing are worth the weight savings? Hrm. The setup of disks, with the brackets and brakelines on the axle, is the hardest part of the setup - and if someone else is doing this so-called "hard" part, then go disks ALL THE WAY!

PS The person who told you about FF being undesirable as a weak and leaky option (??????) should avoid getting high on their own supply.

Good luck making your own decisions,
Bob

1) 9" drum brakes vs disks will not save you 50lbs. They run much small drums than a FF rear like a 14bolt or a 60. (I'd still run disks though)

2) The FF leaking part sorta makes sense. Most 9"s that I have seen use 1/4" tubes and are butt-welded to the center section. They flex a lot more than a D60 or 14. Sure you can weld on a gusset, but maybe Currie doesn't like doing this for customers since this could affect leaf mounts, or coil mounts, etc.

I can never decide if it's best to yell and scream at these people to search or to just ignore them and hope they just go away...
First off I did search but I did not find what I was looking for or what people would have done different. Plus the search would not accept 9 as a search term.

The 9" I have is a 31 spline big bearing unit with 4.88's which I would like to shave the bottom as much as possible, so any pics of 9" inchers wich have been clearenced would be great.

UPNOVER-----You underestimate the power of the low compression, High blowby 2.5HO.:flipoff2:

what diff does the currie HP unit use? i know they use an 8.8 ring gear, so i'm assuming they have to use an 8.8 diff? a buddy just picked up an 8.8 diff to replace the busted spool he has in his HP currie 9 and called me to say the 8.8 carrier is too wide.:confused: :confused:

anyone have any ideas?

The Currie HP 9" uses a reverse cut 8.8 ring and pinion with 8.8 carrier bearings on a 9" carrier. They do use a slightly different carrier bearing race, it's not as wide. I'm in the process of setting one up know.

You have a good point about the brake weight, I didn't look into that, but modifying the m/c doesn't make me comfortable, and it seems most people I talk to who modify the prop valve have mixed results (some work, most others have problems with balance on the street)

As for the aluminum center section, that would save only 20lbs, so maybe it wouldn't be worth it.

As far as FF, The weakness we due to using a stock locking hub on the rear. I wanted this for flat tow, and if I couldn't use a locking hub, then I didn't want the FF. Although Currie did say it is prone to leaking.

As it was, I was at the end of my budget, so even if I wanted the discs or Aluminum center, or FF, I couldn't have pulled it off.

Thanks for the comments. :flipoff2:



Oh, and Jason R: I have more time than money these last few months, so I had Currie build me a 9". It was not stock, they modified the width to my CJ, installed the ARB, set up new 4.10 gears, and put a CJ type yoke on. Most of these things I don't have the tools to do on my own, so :flipoff2: :D Thanks for the input, though.
