Seat Gear Rebuild - slack in jack screw to adjuster motor housing

[AmabilisCruiser]

Ok - rebuilt my driver and passenger seat gears and it is working fine. However - the jack screw that bolts to the adjuster motor housing has some slack. like 1/8" of play sliding forward and back only on the driver side. All bolts and connections are tight.

While I rebuilt gear boxes of motor housing - I noticed a very sticky gelatinous material on one side of the internal washers (almost certain the side that does not have the nylon washer) - which I removed inadvertently on both seats.

I tried a rubber washer shim to fill that slack and now the gears are all bound up and doesn't operate at all.

Not a critical issue and can end up living with it - but anyone else have this happen and did you find a solution?

My observation and also in another post, the play is not related to the seat gears/housing but there are worn plastic pieces within the brackets that the jack screws travel in. As I recall those pieces are not available separately from Toyota. Someone was investigating having them 3D printed.

One bandaid to the problem is to secure the two bracket on each jack screw off-axis, think of pigeon toed.

Interesting - the Jack screw brackets were tight in my case - the slack was in the gear housing. I put the rubber washer on the wrong side of the housing (it should be on the cover side - opposite the nylon washer). Put the rubber washer in and the majority of the slack was removed and it operates normally again. That should tide me over for a while.
