Fixed rocking front seat, thanks to Dirkintl11 I knew where to look, took 30seconds to remove bolt, my whole bushing was gone, just a few pieces left.
Once removed screw, you see where the rocking motion occurs. Other side bushing was OK no play. Hold nut from inside with blade of screwdriver.
I replaced with a plumbing seal from a faucet repair kit, I had to shave it a little and then put place, carefull it is not very tight at all, I think if you tighten this up you will defeat airbag sensor for passenger(detects weight on seat)!!!! Caution-I made shure somebody "light" sat on seat and "airbag off" light went off. Done !!

Ugh! I didn't realize the bushing could be worn, so I over-tightened mine and broke off the nut. It seems the bolt can no longer be purchased alone, only with the whole $240 seat weight sensor.

I'm going to look in a salvage yard car.

So I got the salvage yard bolt. Now where do I get the faucet bushing to stop the rocking?

Guess what? There are four seat sensors and they all take a special shoulder bolt. Because the floorboard was soaked in back, I removed a front bolt, only to find that doesn't fit. Today I returned to the salvage yard to get the right rear bolt. I also found a good bushing and installed them. The shoulder bolt torques to 10nm and the short torx screws under the seat sensor torques to 18nm. I used Locktite red.

the airbag light didn't come on but I'm not sure all of the seat rocking is fixed.

regards,
Peter

Sorry to bump an old thread but I'm in the same boat right now. Shattered right rear plastic bushing and broken bolt. Has anyone found a good source of these bolts and bushings that's not in the hundreds of dollars?

Thanks!

I found both at a salvage yard for little money but it did take some effort to pull the bits out.

The round bushing seems like something that could be made easily in a 3D printer.
