That housing gear is about 80 bucks. I've replaced both, 18 months apart. Once it has popped out, the nylon gear may have already suffered some damage. I tried putting the cap back in and it worked back out, maybe my gear was too far gone at that point. Oh well, now I know not to slide those seats unless absolutely necessary and definatley without my fat a$$ in it. The Parts guy told me they use nylon gears because they are quieter, sorry excuse if you ask me, they must have been planning for the Lexus model as early as 1990 and figured quiet gears would draw in buyers at the showroom. I'd like to figure out a way to convert the slide motion to a traditional pull lever design, but would take some fabrication work and time, just easier to spend $80. Hopefully they wont run out of those parts.
