And you say the posilock front axle is this something you put in or come factory? i mean i got an 05 SE so pretty sure mine comes with the very few basic but would like a locker but you say something about engaging one tire then pulling a switch and having all wheel lock? (details please)
So of all the genious things Jeep did while switching from the CJ to the YJ, they put a central axle disconnect (CAD) system in the YJ dana 30's. This was a vacuum advance actuator the pulled a vac from the intake manifold through the transfercase to the front axle. Cold mornings, old vacuum tubes, etc wouldn't allow your front axle to engage the four wheel drive.
To fix this, you could install a PosiLok shifted (which was a manual cable that engages the 4WD), or a homemade spring kit that keeps the axle fully engaged, or install some TJ axle shafts.
As I went ahead and bought the PosiLok before investigating all the options, I went with the most expensive route.
If you're drivig a TJ, don't worry about the CAD. And a locker might not be the best option. A limited slip or selectable locker (that acts like a limited slip when not engaged) would be better...
