Steering Knucle pop
Thanks Gapp. I also found that information through a different forum last night. It seems to be a common problem for the Tahoe and Yukon through 2006. They recommned having the dealer grease the Intermediate Steering Shaft Assembly but the problem will re-appear since it's a defective part to begin with. Here's the dealer service bulletin:

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.
Based on recent Engineering validation testing, it has now been determined that either grease ( Molycote Grease (dark color) or NYE Grease (yellowish color )) can be used on all vehicles noted in this bulletin. Either grease will provide a significantly longer interval than replacing the I-shaft itself. Please discard Corporate Bulletin Number 00-02-35-003I (Section 02 -- Steering).
Notice: To properly grease the splines, the I-shaft MUST be removed from the vehicle. Failure to do so will result in a repeat repair and a dissatisfied customer
