for thoes who want a better rear suspetion
ok, if u want to replace your rear struts but dont want factory gas struts
get struts for a 1992 cadalaic deville with the air ride in the rear they will cost u bout
100.00 to 130.00 and the hose kit u need is about 10.00 i did this on my 1990 bonne
and omg the ride is a lot better now this is a neat opion for the older bonne the olny difference between the 2 struts is ones gas ones air oh and you will need to get the adapters for the hose kits to work but u can get them from a junk yard pretty cheap
happy moding

My 2 90 SSE already have the extra air on them. So it is a regular gas shock with the air over them to help keep the ride level. Those are stock on the SSE. Unless you mean that is is only air and no gas at all. Then you would have to make sure that there are no leaks otherwise the rear will drop right down. Come to think of it, I have seen caddy'* with the rear bumper almost scrapping the ground, they must have had a leak and pulled the fuse for the air pump.
I actually had mine replaced last year-
opted out of the air ride ones though. My old ones leaked so bad that all i ever heard was that pump going on and off. I got Monroe sensatracs, and the ride is amazing. No complaints at all.
except the price....

I went the el cheapo route and RTV sealed the rear boots last week. Left it on jacks overnight to dry and the shocks are back to original performance with no pump running. You have to smooth the RTV out and blend it real well.

This will have to hit my list of write ups... I'll be doing this to my 91 LE in the future...
Here is the air strut... This is a Monroe Matic Plus... These are actually Gas charged, with air assist.. I believe that the Gas is Nitrogen..

Here you see the nipple for the air line connector( this still has the factory cover on it )

This is the Monroe air line kit AK 29 with the correct connector for the struts..

The strut on the car...

The line ran through the rear of the strut tower.

The T fitting which is now installed in the plastic next to my hand...

Yes this did improve the ride quality as well as stiffened it up a bit... Makes for a better drive when vacationing with the trunk full..

Mike thats my 95 SE... It uses the same struts as both the 91 LE and 91 SSE... My 95 SE did not have ELC... And I had wanted air struts to help the ride and on occasion an over loaded trunk... I have had as much as 400 lbs back there and it rode level...lol
The 91 LE will get the same treatment, and the lines will be run through the tower as well... But the T fitting may go on the plastic speaker cover under the rear deck just to keep it hidden and clean looking..
This is not my write up, But when I have better pics.... I'll make sure I get a handfull when I do this to the LE and do a good write up for adapting air struts to the Non Air suspension

leveling rear is nice, but I wouldn't call it the best.
Summit also sells helper air springs for the rear of our cars. Might be another option for those who want to haul stuff. Or for other reasons.
