is it just the tilt failing?
they are tedious to work on, especially without a lockplate tool and sometimes a wheel puller... lot's of steps and processes doing column work, a few extra if it's a tilt... but the GM's aren't the worst to work on...
That was the stint at the collision shop that drove me batty, I did all the stolen cars, broken column/dash work...
if it's a failed tilt, put some blue, or even green loctite on em... but it's usually not too hard to find a used column too... when i saw a manual, non-tilt, wiper only column come up for sale, I jumped on it...
