Chris,
Is this axle issue the reason my 2015 Sierra with 6.2’s TPW was moved from 1/5/2015 to 2/16/2015? I called GMC’s customer support line as did my dealer and we both received the same response “We aren’t sure at this time why it was delayed” and “call back next week”? I understood the January date with having a 5+ week restriction on the L86 option when I placed the order in September with the up coming holidays but it was slightly upsetting to have it delayed another month and a half and to get no explanation.
