Drivers seat shifts while making turns or going over bumps

[bigtexan99]

I started noticing a subtle shift / movement in the driver seat when making turns or going over bumps.

Mentioned it to the service adviser while it was in for the PTU replacement and they found that the power seat track had excessive wear.

Replaced part FB5Z-9661711-D under warranty.

There is a TSB that covers several Ford models, including the 2016-2019 Explorer for "Seat Pan Looseness, Lateral Movement, Or Clunk/Thump" (TSB 18-2361) with a relatively simple fix. Some F-150 owners have done it themselves (Link to thread & TSB).
