GMC to Ford

My seat back has started rattling over rough pavement and I cannot find the culprit. I have unlatched and checked all of the components. It goes away when the seat is folded down, but comes back after being latched back in place. Has anyone experienced this issue and found a solution?

Once my jack wasn't secured properly behind the rear seat and it squeaked. After putting it back in and tightening it down, squeak went away. Might be worth a short looking at.

Thanks. I did check the jack, but it is on the opposite side of the truck. My rattle is from the seat back on the driver's side. The rattle goes away if someone sits in the seat or I fold down the back.

Mine has the same type rattle. Really annoying. Right behind the drivers seat. Somewhere.

It could be the power rear window motor. Its mounting points may have loosened over time.

I have had issues with the seat belt when my daughter gets out of the truck and the buckle is turned around backwards. However, I have wrapped the buckle with a washcloth and the rattle persisted. I should probably mention:

1. Remove under seat storage and all items. I do not keep things in my door pockets.
2. Removed the jack
3. Removed everything out of the center console and dash pocket. Never know.
4. Wrapped the seat belt buckles

I did notice today that the BuiltRight seat latch that I installed has play in aluminum release plate. I will try stuffing a few garden hose washers in between to eliminate that as a possible source.
