I replaced centerlink but still have play in steering. What should be checked next for loose steering/drifting at 55/60 mph?

tire preasure, alignment, adjust steering box, worn out rag joint?

Thanks for reply but how do you adjust steering box?

I had same situation - check out "Play in Steering Wheel Post" of 10/30. The procedures are in there - very easy to do. The adjustment screw on 71 was right on top of steering box too.

Thanks, that explains what my problem may be.
