The rear shocks on my 1996 Cadillac Deville are toast and I want to replace them.

My Deville's suspension factory code is "FE1"

I definitely DO NOT want to convert to the suspension system. The soft smooth ride of the FE1 is very important to me and I want to not only keep the air ride but improve that factory feeling if possible.

Do I need a pair of Monroe MA822?

OR

Do I need a pair of Monroe 40046?
http://www.amazon.com/Monroe-40046-Rear-Shock-Absorber/dp/B0047D9TS0

ORRRRR

Is it possible to install the Monroe 40018 Specialty Shock Absorber???
http://www.amazon.com/Monroe-40018-Specialty-Shock-Absorber/dp/compatibility-chart/B000C59LRG

If I simply replace my factory rear shocks with the Monroe 40018 on my 1996 Deville will the CCVSS work?

Will the service suspension light pop up on my dash no matter what I replace my factory shocks with? Which options would make the light on the dash come on and which won't?

How many hours would you estimate it would take to do the rear shock replacement at a shop?

I live in Toronto. Would you recommend waiting to do this replacement in the spring when the salt is off the roads or will it matter much?

Are there other brands besides Monroe that might be better overall?

Thanks for any input guys. Really appreciate it.

Re: 1996 Cadillac Deville Rear Suspension Replacement

My Deville's suspension factory code is "FE1"
that is referring to the "soft-ride" springs and smaller sway bars -
actually has nothing to do with the shocks -

you need to figure WHAT suspension system your car came with -

look at the RPO label on the underside of the spare tire cover -

you are looking for F45 -

that is the code for the electronic suspension -

if you DO have that code -
the Monroe 40018 would be a direct replacement -

if you do NOT have that code -
the Monroe 40046 is the correct one -

the Monroe MA822 will NOT work on your car -
-----------------
MANY owners that DO have the F45 electronic suspension -
decide the additional cost is simply NOT worth it -
and switch to the "passive" or non-electronic shocks -

the vast majority are extremely happy with the ride -
and THRILLED with the savings - $900 - compared to $225 -

personally - I would save the money and go passive if there is that choice -
---------------------

If I simply replace my factory rear shocks with the Monroe 40018
on my 1996 Deville will the CCVSS work?

IF you have the F45 suspension -
and ALL the other electronics are still functioning -
YES -

if you do NOT have the F45 suspension -
the 40018 shocks can not be used -
--------------------

Will the service suspension light pop up on my dash
no matter what I replace my factory shocks with?

that depends on what is causing the warning -

IF you have the F45 suspension -
and IF the electronic parts of the rear shocks have failed -
and THAT is causing the warning -
then replacing the rear shocks with the 40018 shocks -
SHOULD solve that problem -

ASSUMING that ALL of the other electronic components
of the F45 suspension system are functioning correctly -

---------------------
How many hours would you estimate it would take
to do the rear shock replacement at a shop?

about one hour - one and a half would be MAX -

Are there other brands besides Monroe that might be better overall?
I prefer Monroe over any other brand -

Thanks so much for the feedback
However, as you can see in the attached picture I do not see the F45 code anywhere
SO
I am going to order the Monroe 40046 shocks
I do not have the service suspension light on currently. Will the light come on if I install the the Monroe 40046s?

---------------------
since you do not have the F45 code -
you do not have the electronic - CVRSS - suspension -

the Monroe 40046 is the correct shock for your car -

if you don't have a warning light on now -
you won't with the new shocks either -

Re: 1996 Cadillac Deville Rear Suspension Replacement

Thanks basscatt I really appreciate the info

1 more question for ya...

I wanted to change the coil springs as well. There are so many options out there. Do you recommend any particular brand or stiffness to replace mine with? I know the factory coils are about 275 pound per inch if im not mistaken. What do you think?
How much additional time would this add to the replacement of my shocks at a mechanic, typically?

(Might have been 2 questions in there haha)

for coil springs I recommend MOOG -
and for your car - the MOOG 81005 - constant-rate -
$75.28 - with free shipping -
http://www.amazon.com/Moog-81005-Front-Constant-Spring/dp/B00180DVIO

and by the way - when you go to the amazon site -
you will notice it says FRONT SPRING -
ignore that - it is a misprint -
rest assured - that is the correct REAR spring for your car -

1996 deville is a one year only electronic suspension. It is not f45 but you will need to put in some resistors if you go with passive shocks.

----------

The Monroe 40018 will not work on the base deville it is only for the concours. The only option you have if you want to stay stock is the original acdelco shock and they currently go for $1052 a piece.

Only the 96 Concours had the different electronic suspension. 96 Deville is supposed to have the same parts as 94-95 Concours had.

I am not sure if it is the same as a 94-95 concours. What I was trying to say was no matter what trim level all 1996 devilles have electronic suspension and the base setup is called RSS and the concours was CVRSS. When I did my rear suspension last year on my 96 I got the Monroe 40018 and they were not correct and they don't have an aftermarket option so I went passive.

The part numbers are the same, that's what I was going by. I have the suspension out of a 96 in my garage, I don't know what aftermarket parts the shocks are comparable to tho.

my 1995 base Deville had the RSS suspension -

I replaced struts and shocks with passive Monroe -
I had to install a relay tapped into a couple wires in the trunk -
to satisfy the "suspension" light -

What kind of relay and where were the wires located
