I am a fan of fuel injection, 91 and newer has the 4.0L HO engine. I believe you are also away from the dreaded puegot BA10 transmission. The AX-5 or A15 is the stronger transmission. Your most common week link is a DANA 35C rear axle. Stock in all jeep from 87 to current. The axle is very weak and has c-clip retainers holding the axleshaft. A stronger D44 is an option in jeeps after 1998. Basically any jeep plan upgrading the rear end.
