I'm glad it wasn't just me, thought I was nuts, I went to hook my trailer the other day and it rolled a good 2 feet down my driveway then stopped. Couldn't replicate it as well..
I Took a video of the ticking and brought it to another dealer,I told them I already know it's the vacuum pump and they confirmed the noise and swapped the pump. Haven't heard the noise since. I left multiple bad reviews for my dealer and chewed them out via email. Won't buy shit them them ever again. Certain dealers just don't care.
Mine just starting doing it at 10k miles, they will blame my 2 inch drop shackles im sure so i aint bringing it in unless I get ambitious and swap shackles again
Dealer did the work and did a terrible job I traded it in for my 2017 , I'll never take my truck to a dealer for body work ever again that's for sure. Plus I didn't wanna pay for a truck I had less than a year and needed that much replaced. I'm to picky lol
