Seat Bush Rocking

MinorInterior & Trim

The original rubber/neoprene shims inside the motorized seat rail worm-drive mechanism deteriorate into jelly, allowing the entire driver and passenger seats to rock forward and back under braking and acceleration.

Warning Signs:

Seat shifts forward an inch under firm braking and slides back under acceleration, Clicking or knocking sensation felt through base of spine, MOT advisory for seat security
