I bought a used box off ebay a while back, and I'm going to start on a reseal job on it, and install it in my car. Upon inspection I noticed that the pitman arm has some radial play in it. Is this normal, or should it be tight? I'd like to know before I waste my time on a dead unit. The area where the steering coupler connects the shaft to the box seems normal (just a slight amount of play). Thanks!
