update to an oooollllllddddd thread:
we ended up selling our 2wd four door jk. put a small lift and tires and it looked good. we hung out with the local jeep clubs, did the runs up and down the beach, drove off road and never had a problem.
we sold it after about two years though because the gas mileage was horrible and the engine power sucked. she got a mini cooper and now a little ford turbo charged suv.
i still have my yj, which is basically a 2wd. i don;t use 4x4 and currently don't have a driveshaft on the front because i have to get a custom one made to bolt to the ford t-case since i put the engine, trans, and t-case from a bronco into my 87 wrangler. lots more fun to drive and still don't go off road. i will probably never get a driveshaft made because i have never needed 4x4 in all the years i have owned jeeps (roughly 15 years)
I don't feel like working on anything at this time so i sold my yj.
