Check out the many on-line auto parts sources, such as; www.RockAuto.com or www.autopartswarehouse.com. They list two (2) rear shocks for your application, from around $120.00 (each) for non-electronic suspension, to around $420.00 (each) for the electronic adjustable type. Wow! The front shocks are around $26.00 (each) to around $46.00 (each) for the non-electronic types.
The electronic types range in price from $1100.00 each (!) WOW! How much do you like the electronic suspension control?

IM NOT SURE ON THE 95 DEVILLE BUT ON THE 93 DEVILLE EVEN WITH THE CCR SUSPENSION YOU CAN REPLACE THEM WITH A STANDARD FRONT STRUT. CCR STANDS FOR COMPUTER CONTROLLED RIDE WITCH IS ELECTRIC.

yes you can there is some parts companys on the internet that make standard rear struts,your caddy's ride will not be as smooth and if your caddy has CCR (computer command ride) type suspension it will have to be disconnected or the air compresser will come on even if the car is not running and drain your battery. the best possible solution is find some good used air shocks or install manually control air shcks. i have done this on my deville, new OEM shocks for the ccr suspenion are expensive.

Try and have the fault code scanned at a local auto parts retailer; Advance Auto, Auto Zone, etc. Typically, they can scan the fault code for free. Post the results and code here to decipher and help diagnose the problem further. Few questions; how many miles are on the vehicle and / or - on the shocks?

thats not enough to diagnose it. The air suspension system sets fault codes which have to be accessed using a professional shop grade scan tool. The codes cannot be accessed with the inexpensive $50 code readers because they are only capable of reading P-codes which are engine codes. The suspension sets C-codes. That is where to start. if you give me a fault code I'll tell you what is wrong *probably*

try cleaning the contacts in the ignition lock cylinder with electric component cleaner,sometimes that is the cause with the pass-key antitheft system.another possible cause is that your'e ignition lock cylinder is wearing out.

youll need to check the resistance of the key chip with a multi meter.than insert the key and remove the l/side under dash panels.you will see a orange 2 wire harness coming out the bottom of the steering column the wires are white.check the resistance across those white wires.it should read the same as the key. if not the cylinder is bad.if it reads the same your problem is in the security system.

do you mean air suspension while the car is not running?

do you notice any change in the handling around corners or over bumpy roads? has the ride height of your car changed in the rear of car? need more info.

Check body frame mounts may be broken. Replace it.

check your recalls,, i think i saw something in there

flushing the power steering fluid fixed problem!

i drained my power steering fluid and replaced it with Lucas brand power steering fluid on recomendation of a mechanic and in 3 or 4 days the Lucas fluid works its way thru my system and CURED the noise.

sound like a swaybar bushing or mount not really too $$$ to fix barring a broken swaybar

it sounds like a bad ball joint or upper strut bearing mount. a broken sway bar link useually does not cause pulling to one side.a broken sway bar link and or bent sway bar would cause excessive body roll around corners.

have a alignment tech check your frontend for loose or bad parts

is the cylinder turning all the way off?do u have any problems starting?try pushing the shift handle foward and take out the key.does it go to acessory"?"

these parts show snow salt damage.have it checked by a decent shop not muffler joe. youll need to check the level ride.the pump and sensor are r/r behind the tire the sensor is hooked to the axle.youll need to pop it loose and push the arm up.turn the key on and the level ride light will come on.youll see the rear pump up.then spray down the shock with soapy water to test for a leaking shock.then resure the sensor.with 2 people sitting on rear bumper the light will come on and u will feal the car going up in the back and the the light will should shut off.their is a way to adjust the sensor also.gl

I think it was in either 1999 or 2000 GM totally redesigned their vehicle frames, eliminating a bunch or weld joints that will rust out given proper humidity,road salts, etc. Not sure about a recall. You can look it up on this page under vehicle recalls. Believe it or not your vehicle is 21 years old and sounds like it is running good. You might even get a CarFAX on the vehicle to see if maybe was in a collision.

u need to listen go back and read what i wrote.find the linkage to the axle its by the motor.pop it off and push it up then it will pump up.then u will have to ck. the shock bags for leaks with soapy water.the bags are shot more then likely.

look down under more like near the fuel tank.youll see a square sensor that has a arm and linkage that hooks to the axle

Ok, I know my answer was lost in here somewhere. I gave info on factory recalls, and suggested CarFax.

i agree bill im telling him how to check the air ride system.all i hear is rust rust rust im done

u will need to get the car jacked up on the r/r to inspect.the shocks sound shot.dealer is expenive.if u look up parts on the internet companys are selling shocks that will work on your car.gl

this suspension piece your talking about rusting is removeable.its held on by 2 frame bolts.and all the connecting parts to it.remove all them and the unit can be removed.it comes with shocks,spindles and center frame.

There are various sensors in the system. If you seriously want to diagnoise and/or repair it yourself, you proably should have the factory service manuals. First, I would check on eBay for ones being sold. Next, all GM manuals (and Ford and Chrysler) can be bought at www.helmsinc.com Helms 'publishes' manuals for all the US car manufactors. A set of new ones will be around $135 or so. eBay should be about half of this.

Sorry chief, this is complicated than you ever can perceive :(

u need to ck. the air ride.there is linkage on the rear axle near the right side.youll need to pop the linkage off.then push it up.with the key on the compressor will start running. spray the shock bags with soapy water to ck. for leaks
