Take a rag and wipe the junk away from the steering shaft and the centerlink hole. Take a good glob of grease and pack it up all around where the steering shaft sticks out of the steering box. This will help seal the steering box from the elements.
Look at the inside splines on the Pitman arm. You will notice that there are 4 flat spots that match up with the splines on the steering box. Install the Pitman on the steering shaft making sure to line up the splines and at the same time insert the tapered bolt in the centerlink. Put the split lock washer and hand start the big nut on the steering shaft and tighten it to your vehicle's specs.
Install the large nut on the Pitman bolt and tighten it to spec, making sure that while you are turning the nut you line up the cotter pin hole. Always tighten to align the holes, never go backwards! Install the new cotter pin and grease the Pitman.
Now hit the road and keep to the straight and narrow!
