I recently lifted my wrangler 4" and am now running 33's. I also found the 4 banger axles with the 4.10 ratio and put them in. How weak are these axles, and should I plan on them breaking while wheeling on difficult trails?
The front is a dana 30 not bad but could be upgraded for reassurance. He rear is a dana 35, should be an ok axle if no upgrades have been done. But if you have or plan on doing more upgrades ditch the 35 and find a 44 or a ford 8.8. You can find plenty of threads here about an axle swap. Me personally wish I would have ditched my 35 before I spend $1200 on lockers and new gears. My ARB locker has gone out twice now and I'm limpin around to and from work to save he money to ditch the 35. But then again you will talk to some people that are running 35" tires and not a single issue with the 35, so your call.
I blew a dana 35 when I had my cherokee, but I know the wrangler is much lighter. I was just curious to know how other people feel about it. My original 30 and 35 from my wrangler were 3.07 gear and were very sluggish, so I found the 30 and 35 from a 4 cyl wrangler for $200 and swapped them out. Big performance increase, I just need to know if they can handle brutal trails, or if I should put out the effort for an 8.8 or d44.
I'll defiantly look into upgrading my axles after I'm done being with a stock jeep. Oh by the way "California, where everything fun is wrong" the greatest quote I've seen in years
