Hereís what it looks like when your bushings are busted and cause your seat to rock.
Washer A 6; Part number: 90501-S3N-003
Bush A 6; Part number: 90502-S3N-013
Spacer 5 for 2001-2002 6 for 2003; Part number: 90503-S3N-003
First things first, if you have the stock radio make sure you have the anti-theft code for the radio, the write down the frequencies for the preset buttons.
Disconnect your battery and wait at least 3 minutes.
Go ahead and remove the plastic covers from the back and unscrew the bolts (14mm)
Once removed go ahead and remove the 2 bolts from the front.
Tilt your seat forward and push it back to reveal the plugs underneath the seat.
Once it is revealed go ahead and unplug. The gray plug has a little button to push and it removes. To remove the yellow grab the sides and it will slide up and then pop out.
When that is done and seat is removed. Car looks like this.
Hereís my seat out of my car.
Pull on the lever to remove it. Use a flathead to remove the cap of the height adjuster. Use the same flat head to push out the C pin in the adjuster and pull off at same time.
Once off use a Philips head and unscrew the screw.
The plastic piece is held in by a clip at the front, a hook in the middle and a plastic screw like thing at the back.
At this point I have my chair sideways and I remove the 3 nuts and do not discard like the TSB says because you will need them to put it back together. Go ahead and take note of the parts when removed as well as their position as you will replace those parts exactly how it came off.
At this point I removed the nut and the washer. Replaced the bushing. The silver part on the screw is the bushing.
Iíve replaced the bushing and put back the rail ontop. Placed the washer in place and put the nut back on. I have not tight it yet.
Remove the front piece. Replace the bushings in the outboard link.
Place the outboard link back in place. On the left side there is a spacer then a washer. On the right there is just a washer. Screw the nuts back on. If you have the chair on itís side like how I did. Do not put the plastic piece back on till last so you donít scratch it up.
Flip the chair over and remove the screw (14mm) holding the seat belt buckle. Careful as there is a collar, spring washer, and toothed lock washer underneath the seat belt buckle.
Flip the seat belt buckle over and out of the way. Remove the 3 nuts.
Once removed go ahead and do the same procedure on this side as done on the other side. The only difference is that for 2001-2002 vehicles the spacer for the inboard link is not put back thus you will have 2 spacers to use for the back screw. That is why I said 5 spaces for 2001-2002 models. 2 spacers on the outside and 3 on the inside.
For the back nut for the 2003 it says to discard the spacer on the back screw, then it says to install 3 spacers on the back screw. At this point you will be short 2 spacers. Thatís why I noted earlier to buy 6 for 2003 models. 2 on the outside and 4 on the inside.
Once all that is done, go ahead and put the plastic piece back on on the outside part of the seat. Lever and the adjuster back on.
Once thatís done go ahead and put your seat back in the car. I kept my wires and the clips intact and put it back together the way I took it out like so.
Then I just bolt it all in place. Reconnect the battery.
Turn the ignition switch to ON(II) and check SRS. If indicator comes on for 6 seconds and turns off. Youíre good. Stays on check for codes and troubleshoot.
If stock radio put back the anti-theft code in and set back the radio station presets.
Set your clock and any other setting which you had.
This is a definite for my list of repairs. I have had a rocking chair in my car for years now. The first time it happened I was able to just tighten the said nuts and it went away. The second time was a no go. I have been rocking ever since. Thanks.
I came across the TSB for this shortly after buying my car last year. I have not been looking forward to the trouble of pulling out the seat etc. Thank you so much for what looks like a superior DIY report. www.bkhondaparts.com prices:

I am contemplating substitutes from my local True Value hardware store and/or the junkyard.
I took my driver's seat out today and inspected all six seat frame bushings. Thanks to the photos and directions above, along with the TSB, it is a pretty easy job for someone with wrench etc. experience. The rear inboard bushing and the rear outboard bushing were somewhat chewed up. As an experiment, I switched them with two good ones from the front. The rocking is gone for now.
I have removed Honda seats before and have become acquainted with clips and hooks attaching plastic covers like the recline cover. I still managed to break the recline cover middle hook and chipped off a piece of the rear outboard "plastic screw thing" as oddmut calls it.
The bushings are made of a metal. After looking at them, I do not expect to find anything at Lowe's or True Value to substitute for them. I am going to keep thinking about this though. I wonder how long they last in general. $3.50 each from online OEM parts places is a lot. With luck in a few years my local junkyard will start having these newer Civics, and I can get a handful of the bushings now and then from it.
--I torqued the four, 10 mm nominal diameter bolts (14 mm socket) fixing the seat to the car frame to 29 ft-lbs., per the 92-95 Civic manual for one of the 10 mm bolts holding the seat to the car frame. Anyone have the shop manual torque for these four bolts? The TSB gives the torque for all the other bolts involved here.
-- The TSB calls for four spacers. Per the TSB, three of them go on the rear inboard mounting stud. The fourth goes on the outboard side, but I cannot tell where. Anyone know?
-- Is there any reason not to re-use the six old washers (the ones with the rectangle shape cut out of the middle)?
