most bend/break Tie rod ends. CV shafts can break, especially on cranked TB's.

If one breaks you can swap it out, or carry a spare stub shaft to get home in 2wd. just like your XJ, they use unit bearings and rely on the hub nut to hold it all together. if you pull the shaft, good chance your unit bearing will fail on the drive home.

otherwise, not many real trail breaks i have heard of with the IFS.

however, if you decide to crank it, be prepared to replace ball joints on a regular basis.

you can fit 33's with only a little crank, that is the route i would go, 35's won't much it much better off road than the 33's will.
