Help with steering box ?

[mossinc]

The main problem is you can feel a jigle in the steering when ever there is tension on the wheel(like going around a corner while hitting a bump). I had this same problem 8000 miles ago and they replaced the tie rods,pitmin arm, and idler arm along with an alignment witch fixed the problem.The problem returned so when I had her in last, for the oil line fitting I said check her out. The dealer "says the tie rods and such are tight but it looks like the steering box has some play in it and to drop it off another day to test it". I dont think they know what the hell at this point.
