thanks for the pics. I guess I did not dig deep enough into the thread to find that. I will give it a try, after I give the dealership an attempt at correcting it.
I have a 2014 1500 Seirra crew cab and have been experiencing the same drivers seat movement from 4000 miles on. Now I have 9000 miles and it is really getting annoying. I will notify the dealer when it goes in for an oil change about the issue. I hope there is a fix for it, and parts available. Not overly impressed with the amount of little quirks that I have been experiencing with the new truck. I am beginning to wish I hadn't traded in the 2000 K2500 crew cab on this one.
