My use for the Air Lift 1000 air springs was somewhat atypical. My 1986
Chevy Celebrity Wagon was sagging in the right rear, and new shocks
didn't help. Upon closer inspection, I found that the right rear coil
spring had broken. While proper procedure would be to replace the rear
coil springs, I looked for other options, because the spring replacement
would require disconnecting everything from the rear axle and dropping
the axle, while supporting the car (somehow) elsewhere. Because of the
age and rust on the car, I always put the jack under the rear axle when
lifting the rear end, as that is the strongest, most secure lifting
point.

So I looked into Air Lift springs. I got a good deal on eBay, and
proceeded with the installation in the broken spring. To install the
air bag, you have to squeeze all of the air out of it, fold it like a
hot dog bun, insert it between the spring coils, and maneuver it into
the upright position. This was hard to do. Maybe it would have been
possible on an intact spring, but with the decreased height in the
broken spring I couldn't get the air bag into a coaxial position. I was
ready to give up, pull it out and list the kit on eBay as "my loss is
your gain." But I couldn't get the bag out of the spring either.

So I managed to position it with the air inlet in a barely accessible
spot, connected the air line, and inflated it. It did work. It
levelled the car. I used all of the air line, running it up through
the window into the car's interior, with the air valve at the end, so I
can adjust the air pressure to my liking.

I didn't put the other air bag in the kit on the other side. I am
saving it in case the one I installed fails.

All in all, I would call this a successful project. It was certainly
less work than replacing the coil springs.
