Yes, what GKarpen said is all corrrect.
I would only add that you can take loose the upper u-joint of the intermeediate (sliding) steering shaft [it connects DOWN to your Steering Box, and UP to the lower end of the Steering column] with one bolt - you must REMOVE it, not just loosen it, note.
Anyhow, slide your intermediate shaft down and check it for excessive play, try turning it left & right and see if there is a bunch of movement BEFORE the front wheels respond. If so, it's worn and needs replacment ($ 155 at Dodge parts, roughtly).
If fairly tight (say 1-3 degrees of rotational play, approx), then check for steering column lower bearing play by grabbing the end you just removed the intermeediate shaft from (it's got a spring fitted to it) and move the truck side to side with force.
{This is the part that pokes out from the Firewall, note }
If you feel much play - clicking, movement amounting to a 1/8 or more, that's probably the culprit.
It could be a combo of both, which is likely when our trucks age and get a few miles.
You can try rotating the spring a few times and this sometimes 'resets' the play and you can have a few miles of silence before it dis-lodges again, and the noise & play return.
Hope this helps. Our steering fix kit will replace the lower steering column bushing / bearing assy and 'tighten' things, if you determine that's your issue.
