93 YJ Axle Question
after hearing descriptions of terror and fright regarding the dana 30
and 35 axles, i'm wondering what would warrant me replacing them, and with what, and at what cost and difficulty? i am not a full time off-roader, but i do put my vehicle to the test, at least i think i do (probably being stupid than anything else). currently running: 93 yj 4.0 3spd 31x10.5 BFG MT's 3" shackle lift (yeah, i know, you don't have to say anything) current plans: a real 3" or 4" suspension lift (something from black diamond or similar) drop pitman arm adjustable track bars locking diff's (aussie locker or traklox) cable operated front axle engagement winch maybe upgrade to 33"s?? is this a pipe dream or what? -- Ben Jerew ASE Master Technician New Country Lexus of Latham, NY Amateur Off-Roader |
Re: 93 YJ Axle Question
The Dana 30 is actually not a bad axle until you get into serious hard-core
stuff where you're running 37" or bigger. Built with decent hardened aftermarket axle shafts like from Superior Axle or Warn, a Dana 30 does well with 35" tires and serious wheeling. So that axle can likely stay in place, though replacing that two-piece axle on the passenger-side with a one-piece axle that also gets rid of the problematic disconnect system is a good idea. For most wheeling, a Dana 35c is "adequate".... but if you wheel seriously and test yourself and the Jeep with bigger than stock tires and lockers, the Dana 35c is clearly not strong enough, mainly the axle shafts are too small and they break. A Dana 44 upgrade is the next bigger axle and works well for tires up to around the 37" size, though really tough wheeling requires its axle shafts be upgraded with hardened axles from Superior Axle. Dana 44 axles are good because they're common and inexpensive, and can be a relatively easy upgrade. Other axles like a Ford 8.8 or 9" are good too but have a bit more to do first before they can be installed.... both are stronger than the Dana 44 but the Dana 44 is more than strong enough for 99% of offroading needs.

Another option for the rear is a reverse cut Dana 60. The advantage, other than the strength, is that the pinion in on top of the axle, not the bottom. This helps with the driveshaft angles in lifted applications. Mike |

Re: 93 YJ Axle Question
But a reverse cut in the rear is not as strong as a non-reverse cut axle in
the rear. A reverse-cut is stronger up front, but not in the rear.
