So I'm thinking about not doing a 14b rear...

I was just thinking. They have these kits to fit dana 70 ring and pinions in 60 cases now. I'm gonna be doing a 4 link rear so I want to build a rear I'm gonna stick with. I was just thinking that if I built a dana 60 with 70 gears in it I would pick up a serious amount of ground clearance w/o loosing any strength wouldnt I?

That is an idea.
I already have a rear D60, and I have some D70 HD shafts.:dunno:
 
If you're going to go to that much "trouble" I'd be sure to use 1.5" axles which most likely means boring the spindles.

I wonder if there is a way to put my 35 spline 1.5" HD shafts in the D60, maybe cut and spline them on the outside and have some locking hubs on them.:confused:
 
I can't think of who but somebody makes a full floater kit that uses drive flanges. Given enough budget I'm sure locking hubs would be possible but it would require custom hubs.

The biggest problem is the spindles on most D60 housings (even HD's) have something like a 1.4x" inner diameter so 1.5" shafts wont fit. I bet you could find a boring tool moderately reasonable on boeard somewhere. That's got to be one of those tools you have to buy but really only use it once.

Isn't the 14bff spindle same size as a D60 spindle?
Can't I put a 14bff hub on if so?
Or did I get my facts mixed up?
 
Would be a lot of work to make the 60 with 70 internals work right. I know the 14 can be an anchor but its cheap to build and stupid strong. Do a little smoothing on the bottom of it and it'll be a lot better, makes it catch a lot less. Gets smoother as you drag it over rocks too :whistle::haha:.

I'm not sure about using a 14 bolt hub on a 60. I know 70 and 14 bolt hubs interchange.

As for the work required to use 70 parts in a 60, it's easy now because JanztEngineering offers a kit. A few special bearings and a little grinding and your done. From what I read on pirate it takes about 2~3 times longer than a typical gear set up. Not bad considering the strength benefits.

Hey man you holdin out on me? Where the **** did you get rocks from!!!!! :thumb:
 
What is wrong with a stock D60 rear? I've always thought a 14BFF was a bit overkill anyway in 95% of the rigs out there.

Nothing wrong with a D60 rear if it's a full floater.
It's just the thrill of building something different.:haha:
I most likely will stick with the D60 rear, with a d44 front on my waggy, I already have 14bff in all my GM's.:waytogo:
Except the new dually I got has a D70 HD
 
Plain old rocks, not rockwell axles :haha:. oh you mean where I found rocks to drive on:doah::whistle:. There's plenty out at Rauch Creek, there's one trail called rock creek that's 2000 feet (yes 2000 FEET!!!) of 3 foot average boulders. You get some serious whiplash on that trail :eek1:. It's a good way to smoke a clutch too if you're not careful, but it's wasn't my rig out on the trail. Was in Ryans jeep. When you go crawling and drag the rear over every boulder it will get smoother :haha:

Ripolls?
 
Yep. That was back last spring. He's got that thing ripped all apart, again. Doing a backhalf with coilovers. Should be cool when done.

Yeah I saw some of the photos on Facebook. That thing will never ever be done.

Very true, "done" is a relative word when talking about project trucks. There's not much left of the original YJ. Personally I think he should of just waited and built the full tube chassis he really wants, but it's his truck and money. He also wants to race at Line mountain this year. Tons of work to make that happen though, not sure if it'll happen.
 
The 60 ring and pinion is not the problem in the rear, its the smaller axleshafts. The tool to bore your spindles out is about 400 bucks. A local machine shop quoted me 300 to do it and it makes the spindles a little thin but most have not had problems with it. Shafts I would imagine are probably 2-400 bucks then the locker. So I bet you would be into it over a grand.

You can shave a couple inches off a 14 bolt. This is on my list of things to do next winter. Its a nearly free modification if you have a welder and some plate laying around. diff cover can get weird but not to hard to build.

That will give you over an inch more clearance than a 60, of course I am going to shave my front 60 too.
