How do you take the play out of the tilt steering on a 77 Camaro LT?

The bolts that hold the tilt steering together work loose and need tightening. You have to take the column apart including the bowl and tigthten them. You need special tools.

If you take the initiative to purchase the tool, pull the tilt wheel pins and then pull the knuckle out, be sure to purchase a bearing kit and replace the bearing while you are in there. A lot of the "looseness" you feel in the wheel will be due to these bearings wearing out over time. A good kit includes the igition swtch actuator. Replacing this at the same time will save you a lot of hassles down the road.
