I need some help with this part, RE: seat wobble...

So, the wobble/rock in my driver's seat has gotten worse (07 Tundra CrewMax Limited). I removed the seat and I think I isolated the problem. It is a bolt, cranked down and it still has slop. It looks like there was a washer or bushing here at one point that may have disintegrated. There were some remnants of something--not sure it was plastic or metal? I bought the truck last year from a gentleman that was on the hefty side. I imagine the seat took some abuse with him getting in and out. Anyway, I looked a little online and can't seem to find a seat schematic that shows this assembly. Please take a look at the pics and let me know if you know of a bushing/washer, etc. that was supposed to go in with this bolt to make it snug, or if you can point me in the right direction. I sure do appreciate any help!

 

Well, it's complete jerry rig bushing, but it worked. Here's what I did:

The same bolt and assembly is on left and right hand side of the seats. Symmetrical. I just pulled the bolts out, grabbed a piece of 1/4" teflon that I had a sheet of laying around, drilled a 9/16 hole, put the bolt in the hole, traced around the bolt head onto the sheet, took the bolt out and used my heavy duty milwaukee scissors to cut the tracing out, popped the bushing back on, screwed it in to test it out, found that it worked, unscrewed it, threw some loctite on there, then put her back in. Put the seat back in and it's rock solid. Not sure how long it will last, but at least I know the fix, and it's pretty simple. Just answering this thread in case someone searches for it down the road.

 

It looks to me that you might need a "top hat washer" like these: https://www.mcmaster.com/1281N18/

 

I had a very similar problem on sequoia. I wrapped that bolt with a few wraps of aluminum foil tape. Fixed the problem. Might not last forever but easy enough and holding up so far.
