Hello,

Just recently I have noticed my driver's seat rocking slightly under acceleration / braking. So far the movement is only slight so I can put up with it - but does this potentially mean expensive repairs down the track? It looks like the rocking is coming from the base rather than just the back of the seat if that's possible. Anyone had this issue and fixed it? If yes what was involved in the fix?

 

When the X400 was introduced we got MANY TSBs and the seating was among the complaints.

Here are some really old Bulletins that might help with your diagnosis.
