I have an 86, so it might not be the same steering column, but if it is this will help. I had some play in mine, and did some Internet searching and discovered it is quite common for the Sagina steering column to get sloppy over time. There are 4 torx head bolts that are used to connect the lower housing to the column that need to be re-tightened. Be sure to use red loctite (263) so that you don't have to do it again. Here's a link that will step you through the process.

Hope this helps...
