It isnt easy, but its possible.
If you are mechanically inclined and have a good selection of tools, and a lot of patience, then by all means go for it.
You have to take apart the column down to below the key switch. once you get that far, you will see a set of 4 torx head screws in like the 10,2,4,and 8 o'clock positions. Those are what need tightened. What i did was to take them out 1 at a time and add some red locktite to the threads and re-insert.
I have all the correct tools, and have been working on my Jeep for over 20 yrs now, and the column thing took me about 4hrs.
