Chevy Tahoe 2002 Steering Column Rod Knocking or Rattling or Clunking

This is just one of those things with this model/year of GM vehicle.  When you go over a bump or a turn it sounds like something inside the steering wheel is loose and knocking against itself.  I've heard a bunch of people complain about it.  I lived with this "knocking" for years until I discovered the fix and it so easy to fix.

I know I'm not using all of the correct terminology but I don't think you need to know all that to fix this issue.  Pop the hood and you'll notice you can see where the steering shaft comes through the firewall between the engine and the inside of the vehicle.  There is a single bolt and nut that attaches this shaft to another piece that actually turns the axle/tires.  Take this nut/bolt off which will free the steering shaft.

This is where it gets weird.  You will be able to use the "That's What She Said" line after every other sentence.  Now push the shaft back up into the steering column (towards the inside of your truck), it will easily slide in and out.  Do this in and out motion about 30 times.  This will feel like you are abusing your truck but what is happening is that you are redistributing the lubricant within the steering rod.  The original problem is with the design of the rod, it lets the lube all run to the bottom end and that creates your noise.  Here's some good info and a video on how to fix.
