jus got my FX back today; second attempt to stop the click/minor shift (aka rocking) of the driver's seat:::
history::
i drive with the seat set at it's lowest height, and, with the base angled as far toward the rear as posible (that is to say the front of the base of the seat is higher than the rear, inner, part of the base of the seat)
1st attempt::
01/15/04 service done = ITB03-037 (tracks and pivots cleaned and lubed with silicon grease)
results::
worked flawlessly for three weeks...... then the clicks started back, but with less frequency than before....
in mid feb, it was back to original frequency...
2nd attempt::
02/20/04 service done = _______ (internal failure at driver side seat - replace seat adjuster and retest..)
new lower seat assembly, pivot, and motor installed.... (revised part)
seems perfect now (sounds a bit different when adjusting also, okay!)
good luck... you might have to get the first TSB done before they'll order the new parts.... took several weeks for the parts to arrive, in my case...
all in all, i am very satisfied..
