I recently got tired of having a loose tilt column on my '86 blazer, so I desided to rip it all apart... bad idea cuz there are so many parts in there and it is really confusing. Anyway I went looking online for a fix for this cuz I didn't want to pay $80 to have a shop do it. Most books don't touch on the subject and GM factory repair manuals have horrible drawing and mention nothing of this probably because if they would have acknowledged it they would of had to have a recall. But the fix is very simple, all you need is a steering wheel puller (a harmonic balance puller will do) and a lock ring compressor which you can pick up a craftsman one at any sears for about $20. The web site link says you need an E8 reverse Torx socket, but a 1/4 socket actually fits perfectly over the Torx bolt head! Anyway here is the link with the step by step instructions: http://www.chevyasylum.com/column/tiltcol.html You still have to tear everything out of the column which seems daunting, but with the pictures and instructions it is really simple, I fixed mine in about 45 min!!! -Good Luck!
