I purchased an 04 Grand Prix GT2 around March. Once it started to warm up outside I noticed my steering wheel squeaking on low speed turns. After searching several forums I thought that I should lube my ISS. Before I made it that far I had to take her in because of clunking over bumps being felt up into the steering wheel and they changed the ISS. From what I understand there was a service announcement to update the ISS and the new model that was just installed does not require being greased. So my question is, why is my steering wheel still squeaking??
