Took my 2014 Silverado 1500 into the dealership for this issue. Told them what I have read on this blog. The representative said that his son had the same issue with his 14. Got a call hours later from a different rep and they said they couldn't duplicate the issue. I asked if I could drive and show a mechanic what I am talking about and they said no. That in itself is rediculous! I then went to Home Depot and spent $1.18 on the hardware listed in links above. From the second I started the truck I knew the issue was fixed. Before when you started it would give that same squeak. Went for a drive around the neighborhood and created the same perimeters where I would hear the noise. And to no surprise the noise was gone. I recommend this as a fix.
However, my question is has anyone experienced any issue with doing this. Also would you consider this a permanent or temporary fix?
