G'day Mate, yes it could be baal joints or draglink but these trucks have an inherent problem of the chassis rusting and cracking where the steering pump is connected, I would check that thoroughly. The leak on the steering box could be the that the fluid return hose has cracked.
Good Luck.

I got a buddy that worked at a garage every time a customer would piss him off he would add some wheel weights to the front tires, these people would drive up the road and turn around and come back complaining that the front end shakes very violently. Needless to say he would walk out to the car or truck and remove the weights before his boss could see and the boss would take the car for a test drive and say the customer is crazy. b-(
Anyways my point is check to see if the wheels are properly balanced, sometimes alot of mud can lay on the inside of the rim too, remove the wheels and check that out.
Let us know if you solved the problem.
