I actually had a very similar issue with my older Chevy. Turns out the drop on the drawbar actually caused the trailer to catch wind at just the right angle underneath and cause a nasty vibration. I changed to a drawbar with a different drop height and the problem went away

Hey guys, Did some searching I have found conflicting information Anyway, I have a 2011 Silverado LT non bose with the stock radio, XM, and onstar. I am looking at adding the 2012+ HDD navigation setup to replace the stock radio unit. I know that I will need a seperate amp, wiring kit, and GPS antenna, but my question is does it have to be sent in for programming, or could a Tech II do it. Are the VIN relearns, backup camera programming, hands free, and other features changed with the Tech II or do I need to mail it out? I know on the older 07-11 factory navs you could at least to a vin relearn with a Tech II - not sure about the HDD ones though Thanks

Hey guys, looking to know if anyone has or knows of a 20998064 / 22947767 heated steering wheel that they'd want to part with. This is the full ebony one, does not have the wood grain inserts. Looks just like the regular GMT900 wheel but it's heated. Please feel free to message me or post here Thanks in advance

Hi guys, just finished adding the seventh motor (Trans Temp) on my 03 Sierra 1500 cluster. When I turn the truck on, the needle doesn't move during the self test. Read that if it is dead, my cluster (which I suspect isn't the original) doesn't have the necessary programming. My friend who owns a fairly large repair shop, has the Tech 2. So my questions are, what needs to programmed? Can I do it with the Tech 2? If I can do it with the Tech 2, how do I go about doing it? Thanks for any help
