Hi, I know the problem well. Had 2 different columns apart recently. What happens is the star bolts holding the lower bearing assembly get loose. You have to take everything off to get to them. First the airbag, if you have one. You have to disarm it first by taking both cables off the battery and touching them together. With the airbag off, take the bolt off the steering wheel and use a puller to get the wheel off. Then the dust cover. With the cover off, you need a lockplate compression tool to push the lockplate down while you remove the locking clip. The lockplate comes off, then the the turn switch canceler, then the turn switch. You have to take the wand and hazard button off to get the switch out. There are then 3 screws holding the upper bearing housing on. First remove the key barrel set screw and remove the barrel. Then remove the 3 screws. Next, you have to pull the ignition switch linkage off the gear opposite the key barrel. The linkage looks like a big key. The housing then comes off and hangs on the turn switch. Make sure you catch the bearings if they are loose. At this point, if you don't have a tilt column, you may be able to see and tighten the star bolts. If you have the tilt column, you will have to take it off. There are pins in each side. An 8/32 screw can be screwed in and pried to pull the pins out. Take the adjusting rod off and the tilt mechanism will come off. The return spring and retainer will also be loose. Now you can tighten the bolts and put everything back together. Now, you're going to want to see some pics to help you. Fortunately, there are a lot of these out there. Here is one, but there are many more: http://www.epiccomputer.com/dale/jeepjunk/tilt/tilt.html
. You will want to find one that's like yours--tilt if you have tilt or non-tilt if you don't. Please let me know if you have questions, and thanks for using FixYa.
