for the CRD owners, pop under ya jeep and have a look at the back of the transfer case and see if there is a slip yoke there...
dont want to sound like a sadistic prick but...
some problem dont start till a little while down the track.
ie. after a few miles..
when parts start to wear out prematurly due to sever angles that you put the joints under. eg... stock LCA's, and steering ball joints etc...
i only say this from pass experience.
it took almost like 3 months before i encounter serious vibrations
However, you might get away with it. not all jeeps are the same there are a number of WJ that has the same hight lifted witout problem till today that i know of...
ther other thing i like to know is that did you have standard measurements & final lifted measurements? if i remember correctly, Chrispy had HD springs and he only got 20mm lift.
anyway. it sounds great are you going to post some pics up?
