dana 44, 30 spline, right ?

 

Powertrax makes a locker for the 44 and the 9.25. It's a fairly easy install unless you have a poorly machined differential housing.
There is one thing you should know about a front axle install of a powertrax. Yes, the traction is awesome...scary even! But...When the transfer case is locked, both wheels will be turning equally under power. When you turn the wheels, they will try to pull the truck straight. Oh you'll turn, but not with the agility of an open diff. The only solution is a Posi lock system to unlock the long side axle.

bump. still looking for first hand experience... anyone got anything good or bad to say about this thing ?

 

No personal experience but you seem to have the right idea. From what I'm reading, you wouldn't want one in the front but you're only considering the rear. I'd do it.

 

a review, not sure how trustworthy, but seems straight up.
rear... http://www.rockcrawler.com/techrepor...x_tj/index.htm

front .. (probably not a good idea w/o a posi-lok disconnect .... why not ? my opinion - if you have a slippery condition such as ice, snow, or mud and the outside wheel slides rather than turns faster than the inside, then it will not unlock, and you will keep sliding. in 2wd with posi-lok in the disconnected axle position, then while the differential is locked, the passenger side is still freewheeling, so you shouldn't get any wierd handling properties. when you do shift to 4wd (posilock disconnected), you have 3 wheel drive with open (disconnected) passenger side. 4wd (posilock connected), you have 4 wheel drive locked, and subject to wierd handling, that is, subject to sideways sliding when you are wanting to turn.

That is correctamundo...but boy is it fun! Oh and you'll start breaking stuff with bigger tires on a D-44. The side forces on the small axle joints with the locker locked are tremendous. Carry spare axles.
Based on my experience, a rear hardlocker would be awsome. Keep in mind that an Auburn or other similar unit replaces the entire carrier. A powertrax is technicaly a tad weaker because it fits inside the factory carrier. I'm not saying that you would break it, but I have seen failure. Again, depends on the size tires and what you're gonna do with it.

 

I'm thinking that since he wants to keep it as a DD with an occasional foray into some moderate off-roading ... use the powertrax in the rear and either leave the front open or use a true locker up there so he can open it for on-road use and then lock it when he needs the extra off-road traction.

 

I can tell you next week. Just ordered one and should get it by this weekend hopefully.

 

you're the MAN.
