I had to take my truck in 4 times for this issue. One time they replaced the pad. Didn't work. Next clips were changed. Still had an issue. I then recorded it with my phone and set it in to the service writer. That helped and it got the manager involved. The 3rd go around they took it to another shop and said it was fixed. They put more foam in the seat and said that was it. Well still not fixed. The 4th go around the manager laid in the back seat and put his ear to it. He heard it from the frame. They replaced the Frame of the seat and 2 months later I still don't have the issue. Such an annoying process but it's over with now.
