I don't know where you got your information from, but the Dana 30 axle will handle a locker or LSD fine, as long as you're not trying to run 44" tires on it. <img src="/forums/images/graemlins/smile.gif" alt="" /> Everyone I know who uses their Jeep off-road a lot has some kind of traction-aiding differential in their Dana 30.

I've had a LockRight locker, with 4.56 gears, in my Dana 30 for 13 years. First 5 or 6 years, I ran 32" tires, and the last few years I've run 35" tires. Absolutely no problems with the locker.

The only problem with a locker or LSD in the front occurs if you're planning on using 4WD on light (less than 2 inches) snow on the pavement. Engaging the front axle with a locker or LSD in such conditions can get squirrely.

My CJ7 is used 95% off-road. In conditions like above, I just use 2WD. If we get deep snow (over 6 inches), then I'll engage 4WD, 'cause that's just like driving off-road -- slow and cautious.

The best option, of course, is to have a selectable locker in the front, like an ARB locker or an Ox-Locker. Than way you can use 4WD unlocked in light snow, and save the locker engagement for really deep snow or off-road use.
