Creak / Squeak / Knock in Driver Seat Lumbar Area
Any of you who have a horribly consistent and very audible creak/squeak coming from the lumbar area of your driver’s seat should take these details to your service advisor in hopes that they’ll skip the first repair that didn’t work (for my truck anyway) and skip right to the second repair I had finished today that we hope will solve the problem for good.
The way I understand it, the lumbar adjustment in the F150 driver’s seat is a bladder type mechanism that bolts into the seat frame. When you twist the knob on the left side base of your driver’s seat it actuates a spring there on the left side, which in turn pulls on the bars in the lumbar assembly/bladder in the seat back. This puts tension on the bars which bows them out into your back. The other (right) side of the lumbar assembly does not have a spring and simply attaches into the seat frame.
Ford’s first fix was to have my dealer replace the entire lumbar assembly. This saw the seat stay quiet for 3 whole days before the noises came back slightly, and then got worse and worse over the following weeks to where any movement I made or pressure I put on the seat resulted in a 100% consistent and reproducible creak/squeak. The noises come mostly from the left side of the seat lumbar (where the tension spring is) and sometimes a knock type noise coming out of the right side of the seat lumbar.
The 2[SUP]nd[/SUP] fix finished today was a labor only evaluation and troubleshooting of the situation where they discovered that the tensioning spring on the left side of the lumbar assembly was coming into contact with some part of the seat frame or lumbar mechanism. With every shift of weight against the seat, the spring was being contacted and perhaps compressed slightly which was producing the noises. They adjusted the way the lumbar mechanism sat in the seat, and maybe even bent something to ensure the spring had ample room to operate and never came into contact with the rest of the seat/lumbar mechanism at any time. No parts replaced, just some good old fashioned root cause analysis. I hope it stays quiet or it’s going back a 3[SUP]rd[/SUP] time!
Hope this helps some of you, it sure annoyed the hell outta me. And if you have this issue please go report it to your friendly local dealer because I hear it takes about a year and quite a bit of feedback for Ford to issue a formal TSB on things.
