What should I look for under the vehicle for rust? How soon does the 4-wheel drive system go bad/need major maintenance? when do the ball joints / tie rod ends need replacing? What should I check when I go to look at it? Any and all hints/helpful suggestions appreciated for this era Jeep CHerokee. Thanks, Jerry Casper Woodbridge, VA ----------------------- Rust ? Behind the rear spring shackles - in front of rear spring shackles - rear quarters - door skins lower lips - bottoms of doors - floor seams underneath. Check front springs for cracks or splits - usually drivers side for some reason. Check crankcase breather system for upgrades as there were a few around 1990. Brien.
