Hey guys been forever since I have been on here, but would like to get back to being a regular here! Anyways, I seem to have a knock coming from the steering column when the wheel is turned or just idling down the road and running over small bumps? any ideas? I have no clue where to begin to look for the issue? thanks guys hopefully someone can shed some light on this!Justin - Beavercreek,OH

I did the search function up at the top & found this from another poster. Hope it helps.
There is a GM TSB (superseded several times) which addresses this issue. I have access to the latest TSBs (which apply to my '04 Silverado) via my ALLDATADIY.COM subscription, but I hesitate to post the entire thing here. At any rate, here's how it begins:
Steering - Underhood Clunk Heard/Felt in Steering Wheel
Bulletin No.: 00-02-35-003N
Date: March 26 2008
Clunking Noise Under Hood and Can Be Felt in Steering Wheel and/or Steering Column (Replace Upper Intermediate Steering Shaft [I-Shaft] Assembly)

This Service Bulletin DOES NOT include Mid-Size Utilities such as Buick Rainier, Chevrolet TrailBlazer Models, GMC Envoy Models or Oldsmobile Bravada. Refer to Service Bulletin 02-02-35-006A or newer for Mid-Size Utilities.
This bulletin is being revised to add diagnostic information (refer to Diagnostic Tips) to check the lower steering column bearing as a potential source of the noise. Please discard Corporate Bulletin Number 00-02-35-003M (Section 02-Steering).
The entire TSB, including a step-by-step procedure, requisite precautions and tools, and detailed images, is posted (by a FORMER GM Parts and Service Mngr, named Mike) at the following link... I suggest a SAVE TO DISK complete with ALL IMAGES, once this page loads:1988 Chevy C-3500 2wd (no pic)
