Spare parts?

[midget]

Ok so my Ranger project is my offroad only toy and I would like to know the common fail points so I can keep plenty of spares in the tow rig. I figured front Ujoints are a given as well as belts for the engine,both alternator and power steering(ac deleted), so anything else spare axles, tie rods? I honestly am not sure of the weak points. Its a 88 ranger with 34s, 7.5 rearend and Im assuming the smaller front axle since the rear wasnt upgraded, v6 5 speed. What am I missing?

I forgot to mention its got the electric shift transfer case if that causes any problems.
