Looking to build a high pinion 44 rear for my YJ. Can I uses the center from a high pinion Ford front, have it cut/re-tubed graft on all new brake stuff, have axles made and use it in the rear? Using standard rotation gears of coarse! Found a good deal on a front RR housing and just looking for some options. THX

yup

Yup, though you might want to be a little easy on the gas :) I know they are stronger than most people think though. I had one in the front of a ford I have had it on its nose more than once and backed up. This would duplicate the the application you are looking at...I didn't break it.

You can cut the brackets off the long side tube and cut it down to how long you need. That will save a little money.

I would try and stay away from gearing much below 4.56 though if you plan on using it a lot.

Use the big bearing ford 9" axle ends

There is a new 33 spline detroit now for the D44, and you can get shafts from superior axle, or you could have an ox locker.

I would think about forged bearing caps

brace the housing if you can, it will help make everything last longer.

later

I'd think a high-pinion 44 rear would be asking for it. Not a whole lot stronger ring-and-pinion-wise than a D35. Sure, you'd get the thicker shafts and tubes, but unless you're sticking with a 4-banger, you might wanna reconsider... I mean, why go to all the trouble and expense of upgrading if your upgrade turns out to be not much of an upgrade at all? ...And when it breaks, it'll probably be the innards that go instead of just snapping a shaft.

Hey,
If you do go ahead with a HP 44, use reverse cut gears! Not standard cut! Reverse cut gears are used in HP housings regardless of whether they are in the rear or front...

Yep. Standard cut gears won't work. The housing is for reverse cut gears, so you use reverse cut gears.

Ba Ha!:D
You use Standard cut gears in a standard housing and Reverse cut gears in a Reverse cut housing regardless of location ie: front or rear.

Thanks for the insight on the reverse vs. standard cut gears. I will be running 37" MT/Rs, a RR 44 front and am still looking for a rearend. I would like a high pinion 60, but they are $$$ and hard to find. From what it sounds the RR 44 may not be up to my 6cyl., 37's and 4.88 gears in a spool. How strong are the RR 44's in the front?
Thanks :beer:

Maxles will build you a 35 spline rc44 rear. They have lockers available for this. They also use a larger R/P, so you have more meat to that. The one I have seen is on a TJ with a 6 and 36's. It has been beat hard and not had any problems. They are working on a 35 spline front. Check them out, you can reach them at 605-941-6979. There site has a pic of the TJ. www.maxles.com

A RC44 is a15-20% weaker than a standard 44 when used in a rear so 37's will a bit to much for it. A RC60 housing is alot of $ but it is probably a one time thing.

Thanks Erin, I dropped them an E-mail. I'll see what they have to say on the matter. I would rather not have someone build the whole thing, too much $$$$. But, I want to have all my bases covered B-4 I start into this thing.

How can they use a bigger R&P ?

Thats a very good question. If it is bigger then is is a 50 R&P?

Why not look for a 9"???? IF you're willing to do all sorts of crap to make a RC 44, why not find a junkyard 9" and then buy a HP centersection??

Junkyard 9"s are dirt cheap, so even though a HP 9" is $$, the cost isn't that awful...

You can get a 35 spline Detroit or spool too.

Yes, I am looking for the least expensive way to build a HP rear and I already have a HP 44 from the front of a Ford that I want to put in the rear. Last time I checked the HP chunck for a 9" was running around $900+/-.

It will come down to how you wheel and what is your crawl ratio? Be kind to it and if you have low gears then also be careful with it.

I did this already.. I run 35 mtr's and 4:10 gears.

With an ARB. so far its a year old and nothing has broken.

Used Superiour Axles. Stock TJ brakes. Stock Tj splines.

And I dont drive easy on the road either.

They are correct when they say rr cut is 30% weaker than standard. But you want Hi-pinion for driveline . You have to deal with the chances...

Check my homepage. I will try and add some pics tonight of the rear end. It is much cheaper than the RR 60 and much cheaper than a high 9.

Unless you make Badassjeepguy an offer on his rear. I am sure his will be forsale soon. 456 and Detroit/ disc brakes. Curry.

my rear....

Hey BellyUp, Thanks for the picture. My plan is to run 37's, so I think the way to go is a HP60. The cost is steep, but I'd hate to be on the trail and break a R&P. 30% weaker brings me almost back down to the strength of the factory 35...eh! Thanks for all the insight,

Why dont you just run a standard cut 60 or 9"? Dont fall for the hype about low pinion angles, blah, blah, blah. If you set your angles right, you wont have a problem. My CJ is SOA with lift springs, raised t-case, standard cut 9", and non CV 1350 shaft. I have no vibes or UJ probs at all. If you absolutly want a RC rear, get a 60.

Jeeprz.

You might have been able to get the driveline angles correct and not have vibs... But look at how high my driveshaft is..

Measured on the level its 19inches to the lowest point and that is at the pinion yoke. My shaft hasn't hit yet. and thats a year.

Lance can back me up on this. I think his RR60 driveshaft is only 1 inch higher than my RR44. I like my driveshaft. Maybee you dont like yours.. But mine is staying put! :D

James thank you, i was just reading this , and was like wtf... glad another caught this also... btw imho a 44 in the rear isnt enough... i broke the r &p and a shaft on a regular 44... weak!

yeap it sure is, as a matter of fact i have a few considering before i put it up on paper.... let me know if ya want it

Bellyup...

holy crap, change your yoke and get rid of those straps! I've seen enough of these break to start a scrap metal shop!
