Several FZJ80 Land Cruisers find themselves with a broken power seat from time to time, and the most common causes of these are missing white caps, and stripped gears. The white caps can work themselves out of their little housing through use, and once they fall out continued seat use will damage the gear inside, since missing cap has made the shaft and gear inside no longer in alignment with the worm gear.
To see if you're missing a white cap, just look under your seat from outside the vehicle, towards the front of the seat. You should see the little cap threaded inside the gear housing, shown to the left and above. If you see a hole, then voila, you need a new white cap.
To inspect your passenger seat, you first need to remove the seat as the cap location is up against your transmission hump- it's just 4 bolts with your 14mm socket, and make sure you unplug the wiring underneath once you can tip the seat back.
The material used for these is an injection molded in a self-lubricating POM material, using custom designs and tooling proprietary to Gamiviti. These caps are gears are the closest approximation available to the original stock cap, and your best, most affordable chance available to restore that sliding function to your Land Cruiser's power seats.
For seats that have been forced to slide front to back for some time without the white cap in place, odds are good the gears are stripped and/or worn to the point where they are no longer effective. The solution for this is to dismantle the lower gear assembly, press off the old gear from the metal shaft it's pressed to, then press on a new gear. Installation takes someone with average mechanical skills about an hour per seat. If you can change your own oil, you can swap both your white caps and your gears.
Prices include USPS postage, shipped worldwide. Best value is 2 caps and 2 gears, which is usually enough to repair both seats. For this option, click the button below:

Read the instructions. Take your time, pay attention to what you're taking off and where it goes, so you can put it all back the same way.
- Heat the gears- use hot water. Could also put a torch on the metal shaft, but you don't necessarily want to melt the gear, just make it soft enough so that it doesn't break when pressing the shaft into it.
- Tilt the seat up before unhooking the power. This makes it easier to access those two philips screws that hold the front panel on.
