I was thinking the other day how cool a front 14 bolt is then I started to think why couldn't a d70 pumpkin be welded in place of a 60 front and that way you could maybe use original inner axles as they are both 35 spline( same spline cut I'm unsure)
Anyways I mentioned this to a buddy and he tod me about the Jana 76. Basically a d60 modified to run d70 ring and pinion. A d60 carrier can be modified with new hole pattern to make it work. I got my ARB locker sitting in a spare room collecting dust ready for install but now do I order a new d70 5:13 ring and pinion.. Hmmm another project??

Have a read..

meh, cheeto :f02: he was talking about making a 14b front a while back too. waste of time imho when you have good d60 fronts around. basically just a way to try and save money and use what you've got when you don't have access to good d60 fronts, or a way to show off and feel cool i guess.

are you breaking the 60 regularly now? if not, why bother? especially with a tall truck like yours. that low pinion center is gonna fubar some d-shaft angles......

 

No I wouldn't use a d70 pot. It would just be the d70 gears with the machined sleeve to adapt fit the bearing on pinion with the stock d60. Cool idea but I thought about it and a reverse cut 5:13 d70 gear would be hella expensive and I don't know who even sells them! Found a thread with a guy who broke a d70 front with 5:13s so it must be out there..

Down fall to a 14 bolt front is the custom axles needed.

No I'm not breaking ring gears yet. It's just in my head and it's another idea. I'm too lazy to install my ArB as it's getting colder out Im not a fan of working outside as much even though I normally work outdoors. I want snow so I can flog my truck hard though. Soon it's coming..

 

pretty sure the kodiak d70 fronts are low pinion as well. maybe currie or one of the other aftermarket axle companies are the ones making reverse cut d70 R&P's, i do know i've seen hp d70 center sections for building custom axle assembly's though.

 

yeah i have no idea. Maybe someone will chime in that knows.

 

The only thing I have to add is(and no, I didn't read the links)...

You sure a 70 ring gear will fit inside a 60 center chunk? Its 1.25" larger in diameter.

 

there's a sex joke to be made there...

 

Theres about 3 locations in the pot that need to be ground no more than 1/8 for clearance. It's not bad at all. Guys are running this setup now with no issues so far.

 

Hmm, ok.

I'm not sure the larger r&p is really worth the effort/cost. If I got in a position of breaking them constantly I'd either A- buy better r&ps, B-have r&ps cryo'd or C-both. Probably C off the rip but that's me.

 

Larry,
I don't make sex jokes to Canadians.

 

there are a few of these "hybrid" axle ideas floating around on pirate that i've read about and i can't really see a valid point to them besides saving cash by using random parts you have laying around. other than that there's not much sense to them to me.

 

You really don't save that much cash when you consider that most of them require custom parts or machining at some point.


If I were to build anything "different" it would be a high pinion 609 with a fab'd housing. If I'm going custom, its going to be bling custom. Until then my chromo'd 60 will do just fine.

 

Only time I broke a D60 r&p was when a bearing went out first.


35 splines outers and U joints need to become a lot stronger before I'd worry about the r&p being too small.

 

Your wife said there's nothing wrong with the ring gear but the pinion is waay too small.

 

You can't deny it is stronger. Bigger ring gear better contact area, more beef. I agree ring gears arn't always a big issue if properly setup. But really why not do it if you really want to.
Cost you'd be looking at $500. 2-300$ for the kit , few hundred for gears , then sell original d60 gears put $100 back in the pocket. New ideas and engineering makes this sport progress and I love thinking outside the box to make something better work.
