Awesome work here guys! I've been trying for the last month figuring out what was moving in my seat. Came across this thread. Didn't believe this was going to fix it...but it seems to have! My dealer thought I was going crazy and why would this be that big of a deal. I told them this $53,000 brand new truck felt like sh!t driving it (also the tranny is really annoying as well). Many thanks guys for figuring this out!
