I am a long time reader but have not needed to ask too many questions until this week.
Our current drive, 2014 Silverado CC, has started making a loud noise when backing into a parking space at low speed. It seems that when the wheels are turned left or returned from left to center I can hear a pop or load click. On my last visit to the dealer for the infamous ac condenser problem I had them look into this, thinking it was a ball joint issue. They called be back later in the day and claimed they traced the noise to the steering rack due to a binding and quoted $3200 for the replacement and alignment! What great news to hear since the truck only has 70K miles and is all stock.
My old mechanic that we used for our last vehicle, 2003 Trailblazer, has said that he could only get the part from a GM dealer as none of his parts suppliers have a aftermarket rack. I found a rack at Flow GM Parts for around $1400, in the door. The mechanic quoted around 4 hours to replace with an alignment after. 10 years ago I would have tried this without thinking twice about it. Funny how old age catches up with your body!
My question for all is how common is this problem on these trucks? Will the rack or controller need a flash after replacement? If so, would the truck still be drivable to get it to the dealer?
