Terrible knocking in turning steering wheel--repaired under warranty--states shaft, intermediate replace-mileage was 35K now at 55K same problem only louder and wheel seems loose--called dealer--needs to replace shaft again for a cost of $300--I drive my grandchildren to school and take long trips--dealer said car is safe-I am about to make along trip and cannot get the car serviced until my return in a week--this is worrisome when I feel I could lose control of the car if something should break-why would a second drive shaft be faulty as was the first. I have read other complaints about this and my dealer says it is happening to a lot of 2004 Suburban and they expect a recall.
