    trash dana 30

    well i was messing around behind my shop making a steep short hill climb to try with the jeep ..tried it a few times not making and then i heard a crunch ...i ended up ripping the teeth off the ring gear and still not making it up the hill ...i had it but the stupid dana 30 took a shit on me ...guess its time to upgrade to a dana 44

    Looks like my last 2 HP30 ring gears. 30 can be built strong, but yeah, that ring gear is always a huge weak point... 44 is a great option if you can't go with huge tires to compensate for the 60 diff hanging too low.

    Can't say I've ever seen someone putting a giant non-steering axle in the front of a Jeep

    But a shaved 14bolt for the back and a shaved 60 for the front would be sweet!!!

    axles are strange

    seen my buddy wheel his TJ with a 4:1 case, 5 speed, LP30, rollin' on 37's all through Paragon's Hardcore trails without any issue

    then i've seen people bust em on 33's


    I still think the HP30 in the front of my Grand on 33's will be fine

    I know what you mean, I've seen people break em on 31's & a open diff, then i've seen people beat them HARD locked on the street and running 35's in the woods with no issues


    what upgrade you have?

    I'm hoping the 29spline 8.25 will hold up...the biggest I plan to go is 36"s.

    The 35 held up to your 34" LTBS just fine. I think the manual helps, and the fact that you know how to drive it...

    Josh has a HP30 jay, I think I sold it to him but I really dont remember how long ago, or it may have just been shafts I sold him??? Either way its a hp30 in his heep.

    Good hp gears with good bearings (very important) and a good set up will take more abuse than the shafts will 100% of the time... while traveling forward. If they fail there was a reason, be it set up or bearing deflection or they can self destruct in reverse. There is always a reason, a "method to madness" I guess you could say. LP 30's are weak however.
