03 Chevy Silverado Popping Sign In

Hey folks,
I've got an '03 Chevy Silverado 1500 4WD Extended Cab. I keep up on all the maintenance and try to do all the repairs myself but this one has me stumped. When turning at low speeds I can feel a little pop in the steering. I can't hear it outside and it isn't shaking the vehicle. The truck acts fine at highway speeds and doesn't give any other trouble. Any advice?

The intermediate steering shaft has been a problem with these years of GM trucks. Going by your description of the noise and feel of the problem; this shaft is the likely cause?
Here’s the TSB on this.

#00-02-35-003N: Clunking Noise Under Hood and Can Be Felt in Steering Wheel and/or Steering Column (Replace Upper Intermediate Steering Shaft (I-Shaft) Assembly) - (Mar 26, 2008)

Subject: Clunking Noise Under Hood and Can Be Felt in Steering Wheel and/or Steering Column (Replace Upper Intermediate Steering Shaft [I-Shaft] Assembly)

Condition: Some customers may comment on a clunk-type noise coming from under the hood that also can be felt in the steering wheel. These conditions may be more noticeable when turning at low speeds on rough road surfaces.

Important:
• I-shaft P/N 19153614 has been designed to replace previous designed dampened and non-dampened I-shafts. The physical difference in the yoke size will accommodate all vehicles listed in this bulletin.
• Due to the design of the new I-shaft, it is not possible to lubricate/grease the I-shaft.

That sounds like it's exactly it, and I was able to find the parts at GM parts direct for cheap! I've never taken apart anything in the steering column though, is this something that could be difficult, i.e. parts hidden by firewall, press fits?

They’re not all that bad to replace; you may have to loosen the steering gear and lower it, to gain room for the shaft to be removed.
If this truck has an air bag; make sure you disconnect the battery and wait for 10 or 15 minutes before you start the job. Anytime you’re working on or with the steering column; you should always deactivate the ABS system. Disconnecting the vehicles battery; will allow the ABS system’s internal back-up battery to discharge; making it safe to work on, without lighting off the air bag.
