A customer complains of noise or vibration in steering of 2003 Suburban.

A customer complains of noise or vibration in steering of 2003 Suburban. He has changed power steering pump and tie rods. Still he has this same issue. Do you have any ideas as to what this may be? Also, do you know of any factory bulletins on any issues of this nature that GM may have?

There are several TSBs from GM on “Power Steering Shudder.” Some have been solved by replacing the power steering gear and/or the power steering high-pressure line. The exact cause should be diagnosed using the GM TSB for this, GM TSB 05-02-32-008A.
