if you can drive it down the road, of course check the steering,
other have advised you about jeep and rust!!!!!!!!!!!!!
most of these old jeeps have been rode hard and put up wet.
steering is suspect at best, but if you can not keep it out of the ditches, you could be talking more big bucks to make it road worthy.
also, be sure the transfer case works, can you shift into and out of 4x4, also check locking hubs, will they lock in and can you get them unlocked.
check oil levels in all gearboxes. jeep brakes are most times a problem, if they have been neglected.
Note to file: many old jeep have been neglected.
remember what jeep stands for:
JEEP: just empty every pocket!!!!!!
but, i have not been without one in my barn for many years.
