Lot's of pure opinion floating around in this thread..........
Might as well add mine. To the low pinion comments. It really doesn't matter if he puts a lunchbox locker in that low pinion axle, it will fit in a high pinion axle IF he decides later to swap it. Plenty of people run low pinion front axles, every TJ (except a Rubicon) came with a low pinion D30 and there's a ton of them out there. Yes, low pinion is better, stronger with more clearance.
Oops! I meant high pinion.......
Regarding the know it all who says an auto locker effects things in 2wd.............IT DOESN'T. I've run one, and know plenty of others who have run them, and have read the experinces of many more who have run them, and they are virtually invisible in the front end when in 2wd. You might hear them click a little, and you might feel the click now and then if you're sensitive, but it won't effect the driving or the handling of the vehicle in any way. Based on how an auto locker works, it can't do anyhting but ratchet freely when the front axle is not engaged.
Also, I wouldn't bother swapping a 29 spline 8.25 for a D44. The strength difference is insignificant. later on you can put a set of alloy shafts in the 8.25, they've held up decently well to 35's.
