Question How strong is a Dana 30 front axle?

I'm looking into doing a solid front axle build on our 2004 Jeep Liberty and am wondering
just how strong a Dana 30 front axle is.
The reason for a Dana 30 is that they are relatively inexpensive second hand compared to
other Dana front solid axles and I already have an ARB Air Locker and a set of 4:10 gears
for a Dana 30. All the rest shouldn't be to costly to accumulate over the course of 6-12 months.

I am not looking to build our Rig to the same specs as Troy's:
(A fellow KJ owner and buddy on http://www.jeepkj.com)
http://www.cardomain.com/ride/312121...ted-utility-4d

But something that will fit 285-75-16's(33 inch) or 315-75-16's(35 inch) tall tires.

For those folks here that do not know, a Jeep Liberty has a Dana 30A; an aluminum independent
suspension front differential.
Not the strongest unit and limited to 265-75-16's or 32 inch tall tires.
And even then it's pushing it as far as being able to wheel it somewhat hard before the diff self
destructs!
http://www.funinbc.com//forum/showthread.php?t=111306

Yes, there is an IFS Steel Dana 30 retro fit diff available...
But just the empty housing sells for $1500.00* U.S.
Then you need to source heavy duty inner and outer CV joints.
And then you are still vulnerable because it's an IFS setup!

Jen and I have thought of trading in our Rig for another Jeep model,
but at the end of the day any modified vehicle (Especially a modified Jeep) doesn't particularly get
a great trade in dollar amount!
Selling it privately is also a no go as most people who are looking for a Jeep are not looking for a
modded KJ!

Our Rig is paid off and we don't owe a dime on it!
So keeping it makes sense. That and we want to keep our KJ and build/modify it into something
more unique!


We look foreword to your opinions and suggestions


*I'll go the route of a steel front diff if it ends up being more cost effective in the long run.


Cheers
Ry & Jen

For the type of wheeling you are talking about doing a D30 would be more than adequate. A super 30 with the bigger axles would be a better find.

I got a Dana 30 diff for ya if u want, it's got 3.73 gears in it already,

I run 35's on mine, no problems but the unit bearings going every 2 months, used to run 37's on one unlocked in my last jeep, no problems,
Jj runs 36's on his, u will be fine, if u lock it get chromoly shafts and don't go bigger than a 33 and u should be ok

Thanks for replies guy's, I'll start doing more research into other components such as chromoly axles and such.
Any recommendations for brands? Yukon, U.S.A.?

Cheers

Yes, so the decision is where do you want the weakest link to be? If you were planning beatings I'd stay away from moly shafts as a broken u-joint is better than a ring and pinion.

or, for the price, try getting the ring and pinion cryo treated.. its cheap.
