The kit comes with easy-to-follow illustrated instructions, but we also furnish a toll-free number to our tech dept, where they can get their questions answered.
How many hours does it take for the Lexus LS400 Air Suspension Conversion?
You should figure between 3-4 hours times the shop's labor rate, but this can vary greatly depending on the shop.
Will the car sit lower than it did with the air?
No, if anything the car will sit a little higher. Our experience is that some front tire and wheel combinations may scrub in turns at the stock height.
These instructions are furnished only to give you an idea of the task at hand. When installing your kit, please use the instructions furnished with the kit, as they will include pictures to aid with the install as well as the suspension warning light-out instructions.
* Remove all four wheels.
* Bleed the residual air pressure by disconnecting the one touch air connector of the height control valve.
* Disconnect the height control sensor link from the shock absorbers lower bracket. remove the nut and disconnect the sensor link.
* Disconnect the steering knuckle from the upper ball joint, by removing the clip and the nut.
* Using a ball joint separator tool, disconnect bottom of strut from lower bracket. Remove the bolt and nut.
SUGGESTION? Don't have a ball joint separating tool? No problem, an old trick is to loosen nut of ball joint almost all the way, but leave it on the ball joint stud a few threads. (just in case" you accidentally strike the ball joint threads, the nut will clean the threads a bit while it's coming off) Now, being careful NOT to hit the ball joint itself, strike the KNUCKLE and hit it like you mean it! If all goes well, the ball joint will pop loose so you can continue.
* Support the steering knuckle securely.
* Disconnect the old strut from the lower bracket, by removing the bolt and nut.
* Disconnect air tube from the strut. Remove the grommet and disconnect the air tube from the cylinder.
* Remove suspension actuator on top of the strut by removing the three nuts and actuator cover.

* Remove the two nuts and actuator.
* Remove front air strut by removing the three nuts on top.
* Install the bottom of the strut into the lower mounting bracket and secure with the bolt and nut.
* Reconnect the steering knuckle to the upper ball joint.
