1990 Buick Riviera wobbly steering column

Assuming its tilt. Where column tilts are two press in dowel pins. One/both have come loose or popped out entirely. Remove panel beloww column. Then remove plastic shroud directly behind steering wheel (covers ignition cylinder as well). U should be able to see pivots(dowel pins) or where they should go. These pins can be purchased cheaply at dealer. Believe they also make slightly oversized pins to account for wear.

Did u fix your steering wheal? Im haven same prob mine really loose.
