4WD engage or not
I just finished having a True Trac posi put in my Dana 30 front axle as well as a Trac-lok posi in the Dana 44 rear axle. What I read all over the internet tells me that they both act automatically in engaging when needed, and otherwise operate as "open" when not needed. I presume I still need to use the 4WD (HI or LOW) selector to put my Jeep into that mode and then the posis can act when needed??? When I am not in 4WD mode, will the rear posi still engage if it begins to slip, say, in the rain??? Thanks very much.
I am not trying to be a smart *** BUT these questions should have been asked before you had these parts installed. Basically you have the jist of how they work. Except a posi unit works off clutches in the differential. They are "always" working. There is no "on and off" with a posi. The clutches allow the wheels to turn at different speeds during turns without the squeeling and banging of a true locker. Hope that helps.
Both the above are correct. Your rear posi will always act as a LSD. In 2wd your front is just an open, unpowered axle - there's nothing to slip because there's no power. When you're in 4wd, now there's power and it will also act as a LSD.
