It suggested adjusting the play on the input shaft first , I have never done this so far
if it is a 97 Ram 4x4 they are aweful to drive , I have a kit available to reduce [drastically] the play in the steering , it is a brace that supports the steering box below the pitman arm , this will take most of the play away , the othert problem is the bar from the diff to the frame with hte stupid tie rod end on it , the tie rod wears out quickly & allows the diff to wander side to side there is also a kit to fix that problem that eliminates the tie rod end & usesa cross bolt design at both ends both upgrade parts cost approx $850 can to buy
