35" tires with front dana 35

I'm wanting to get a 2012 Wrangler Unlimited. And want to add a lift and 35" Duratracks. I would only go wheeling maybe twice a year, mostly trails with some rock (Natural Bridge, KY; Livingston, KY; etc.). I've love a rubicon but hate the extra $5k expense for just a few rides a year!

My question is... how many of you out there with 35s and front dana 35s have had problems?

I run 35's on a front 30 just fine. I wheel carefully though, which you should anyway Keep in mind that many here will advocate upgraded steering and brakes along with you move to 35's.

Also, if you have 3.07 gears, you will need to regear before mounting them. I have 3.73's in the diffs and it is on the very bottom edge of "tolerable."

I ran those Duratracs for over a year with hard wheeling on a dana 30 and it held up just fine even without gussets and sleeves.

The smallest ratio the JK has available is 3:21s. The wider wheel stance compared the TJ Gen I Dana 30 axle has given the axle tubes a better chance of bending even though the Gen II Dana 30 has thick tube walls.

To sum it up, if you're just doing light wheeling such as fireroads you'll be ok. But if your into beating on your rig pretty good I highly recommend Gusseting and Sleeving with 35s.

There are more than a couple Unlimiteds that have had damaged housings possible caused by larger tires and the smaller front axle (With both Dana 30's and 44's). My housing broke with 33's and a low speed hill climb where I spun the front tire a few times.

At a minimum I'd consider sleeving and gusseting the axle to provide that extra bit of protection. The Dana 44 for the JK's is the same tube thickness as a Dana 30, so upgrading to a Rubicon still isn't going do much for you.

It's a rare situation to experience a breakage, but IMO better to spend a few hundred bucks upgrading the axles just to be sure than experiencing a break on the trail.
