Hi Verbatum

Yes, replacing the self leveling rear shockers with gas shocks, is the way to go.

The self leveling system was notoriously problematic.

Due to either to the leveling sensor going faulty, and making the car go up and down, whilst sitting at the lights. ( Do not be surprised to see that yours has been disconnected. )
Other problems are loud knocks over the big bumps, and finally oil leaks from the shockers.

Yes Jaguar in there wisdom, did not make things easy, and new gas shockers will not match your old springs.

I do have all the Jaguar part numbers somewhere for this job, if you want to keep it all Jaguar.
( let me know and I will have a look !)

I have seen in the past, Modification Kits being offered in England, but would have to get back to you with source.

I see you are in Canada , and I am in Spain, and not familiar with your spares situation out there.

You will be requiring 2 Gas Shockers, 2 Springs and retaining collets, and plates.

I hope I have been of help.

Good Luck

    Hi Verbatum.

    Amazingly I managed to find the Genuine Jaguar Part Numbers, and parts I used to replace, to convert Self Leveling rear suspension to Gas.

    2. Rear Shockers JCCC 6923

    2. Top Plates MMD 357OAA

    2. Rear Spring Kits JLM 657 (11382)

    2. Top Plate Guides CBC 2933

    2. Shocker Rings JCAC 4771

    2. Shocker Collets JCAC 4772

    2. Bottom Bolts JCAC 5833

    2. Bottom Bolt Nuts JNY 116O41

    These part numbers have probably been superseded by Jaguar, but should come up on there computer.

    Hope this helps ?

    Stay in touch.

    Good Luck !

Air suspension fault light came on in my 2004 jag xj8. a day later vehicle to low light came on. watched the suspension and it continued to work with this warning lights on. a week later the right shock...

if your in doubt about the functionality of the suspension system a quick way to check and see if the static pressure system is working properly is totake a floor jack and raise up the opposing side that you have questions..The system stores 228ps in the retantion tank located under the spare tire.As you force the air to one side the recycle valve will release the air to lower the cars' body.You wil hear it come out,then lower the jack,then the air from the tank will refill the lost air....Turn on the car to initiate the air pump to refill the rear tank,you should feel the car raise up in the front evenly.Last but not least my suggestion is if you think another shock is leaking you can 1st check the caping on the times they will leak slowly on the will start as a weeping leak and you cant hear can get some soapy water and lightly spray it around the enter deck mounts location under the hood where the air lines feed into the shocks...if you see air bubbles,then you can easily pack a towel in the leakage until you find a used shock or rebuilt one off ebay....But you fault light wont display a mil.The fault light only comes on when pressure is lost from the shock,or a static line has failed...causing one shock to lower to be lower..The CAN will trigure a fault code as the sensor detects body uneveness..Usually when this happens you will see a fault code,but I doubt this is your issue.

Need to disconnect air supension on 1994 caprice

I am not sure but.....
There is a level device located on conductor side, below the car near rear wheel. you will find it because is located on the chasis or inmovible place and the lever connect it to the back suspension, so, it the lever will move up and down when you push car defese down. Disconnecting cable harness will inhibit the function.
BUT, Strongly recomend no to disconnect, but fix the original crank problem To disconnect it will modify suspension response of the car and a lost of stability at high speed

Changing rear suspention

the strut/spring is one assembly that comes out as one unit.
The 1989 XJ6s'(USA) had self leveling hydraulic suspension. Is your
new strut correct or has your car been retrofitted to conventional shocks?

Changing rear shocks on a 1990 jag

No. But if can't get it on a lift or high enough to work under will be very awkward. The calipers get in the way when you are removing the springs and shocks as a unit. You can move the part and get it out and down, but you will need to remove the rear wheels and let the rear springs hang down.
Make sure you have a good spring compressor to get the old springs most cases it is the springs that go soft and not the shocks...
Don't assume that it is the shocks unless you know for sure they are bad.

1995 Jag XJ6 Rear Issues...need to fix ASAP.

My 1994 Vanden Plas makes the same noise. I know I need rear shocks. You do also!! Have the rear shocks replaced. Bilstein part number B46 1858 or Koni part  number 30 1377. Actually the Bilstein is the better shock and less expensive.
