don't buy any kit that doesn't include lower control arms. :thumbsup:

:agree:

 

And a 4.5" kit you'll definitely want adjustable lower and upper arms, adjustable tracbar, and appropriate sway bar links.

 

Be sure to do an alignment after any height change. Toe-in alignments are ridiculously easy. Good writeup here http://www.4x4xplor.com/alignment.html

Your front will be fine, you'll just have to pay for a re-gear unless you happen to find a 3.73 D30 to swap in(good luck)

 

You'd only need to change the carrier in the back because the 29 spline spider gears are bigger than the 27s and won't fit in the 27 spline carrier. You still have to do a gear setup even if you're just changing carriers and keeping your gears, so you might as well do them all at once.

 

Unless, of course, you find a 3.73 29 spline 8.25 or D44.

 

As for bearing size, if you mean the wheel bearings, I believe they are the same.

 

Brakes will be the same between 27 and 29 splines.

 

All that's different are the shafts, spiders, and carrier.

 

well if I'm buying a carrier might as well be a full case locker right? I would much rather spend money on an XJ 44 though. I may wait to regear till I can get ahold of one.
