Hello, I have a 2004 GMC Sierra Ext. cab 4X4 SLE with the tow package Z71 off road. Bought the truck used but having a ongoing issue with the steering when only turning Left, it makes a moaning sound, Have replaced the column bearing twice, and also the Intermediate steering shaft upper and lower. The noise continues :-( . Has anyone had this problem with this type of truck, who might have some suggestions on what the problem would be. Thank you in advance for any help on figuring this out. getting pretty frustrated with it.
