Sooo...a couple questions again, what does "x2" mean WagoneerXJ? Second, i'm not sure if i'd want to take the engine out of mine and swap it. My truck is in really awesome condition and 2wd is really the only drawback to it. It's a 92 with 130'000 kms and zero rust, so i'd like to keep the body as is, but if it's not incredibly difficult to switch it to 4wd, i may be interested in that. If not, i might just keep it as a prerunner sorta deal and put on the 235/75 R15's.
