Anyone know which u joints I need for the rear driveshaft on a 98 sport w/ 4.0 aw4? Advance's website has all the moog and driveworks u joints listed as being for the front driveshaft. If you can find their part number that'd be great, my advanced is right down the street and I'd rather not order online. Thanks!

Nah. You'd slip the clutch a lot less and gain some revs on the highway. Probably start in 2nd gear a lot.

Are there any bad aspects of frame stiffeners? If done, should the front and rear be done as well instead of just the "center channel reinforcements"?
I want to throw on a tire carrier and front winch bumper just worried about how it will affect the frame.
How will they affect my lca/leaf sorting mounts and crossmember?

Add a small amount of weight, if welded improperly can crack, trap rust if installed incorrectly, their existence must be kept in mind when doing any future mods (eg sliders, bumpers).
The more the merrier! Your Jeep isn't going to fall apart if you only do the middle but at prices like HD Offroad has, why not do the whole thing?
Not much on their own but if you then plan on using your Jeep you'll want the stiffeners. Remember the original metal has been stressed for a decade or two, these things aren't new anymore. After installation you can tell a difference in rigidity and stability just driving on the street. Would you want the same upgrade for a Jeep that you're going to run offroad and run recoveries with? I think so yes!
At least the HD Offroad mounts have no impact on these. Everything is cut to fit a stock XJ, acces holes etc. You'll want to verify that addig extra width to your uniframe doesn't impede on a bumper mounting up.

I'll check the tire pressure...and thanks for the technical links...it's hard to find good, clear to read, drawings!
