its the intermediate steering shaft.

dont necessarily need to replace it, although there is a nasty rumor going around that there is a better one out there now available from GM that requires no lubing. anyways, to fix this, just get a can of white lithium grease from autoparts store of your choice, get upside down in the drivers seat, pull back the rubber boot that goes around the steering shaft, and spray down into the middle of it. it may help to have the steering wheel turned about 1/4 turn either way. spray till it wont take any more grease.
