It would have been awesome if you posted pics of the installation process, along with a brief write up to go with the pics. Morons like me who drive a 2000 S430 and know nothing about replacing a strut would have found your write up very useful!!
Did you replace just the one strut or a pair (front or back?). What were the symptons you were having that made you conclude your strut need replacing?
An independent shop told me I need to replace my struts but I instead opted to replace the airmatic compressor and relay only (DIY) and haven't had the "visit workshop" message since. However, I have almost 100K miles on my car, and I am wondering if it is time to consider replacing my struts.
Jack up the front of the car, put it on jack stands.
You'll need a 2 ton jack(has a three foot handle and four wheels) which you can find at any auto parts store.
place jack under lower control arm, assuming you have already taken off the wheel.
jack up strut to compress it.
under the fenderwell there is a wire that comes from the side of the strut to the side of the fenderwell, take a flathead screwdriver and pull up that pin to release the strut connection to the ecu. then grab and pull it out of the fender carefully.
get a 5" allen key to pull the two allen nuts at the bottom of the strut.
once they have been screwed out.
GET AN 8MM WRENCH AND SLOWLY! I MEAN SLOWLY! TURN THE NUT ON TOP OF THE STRUT TO RELEASE THE COMPRESSED AIR IN THE STRUT!
go to the top of the car underhood and pull the three nuts. I forgot what size socket you'll need but take those off.
slowly release the jack to drop the strut out.
