Hey glad I found the forum here... Hopefully somebody here can help me out. I have a 2006 uplander which developed a steering noise at about 5000 kms after my first oil change. They changed the boot assembly, which solved the problem momentarly. 1 month later I had a noise, and they changed the steerig assembly, and the noise came back a month later again. Since then I've been going back for the same problem but was diagnosed with insufficient lubrication E7700 Shaft replaced.After talking to a tech he said to let him know if the noise occures when the brakes are pressed. Anyways I've pretty much given up, but the problems just gotten a lot more noticable everytime i turn. I called the Service Manager, and he didnt' return my calls. GM customer service from the 1-800 said to talk to him directly. I haveto say the Customer Service Reps from the 1-800 number are outstanding.
