Hello and welcome to justanswer.com
Yes you have air struts/springs on this vehicle but replaement is not that difficult. You will need to use Jag parts.
i searched internet for 04 strut and keep coming up with at kyb struts, but it doesn't look like what i have on my 04 XJ. kyb doesn't fit, right?
For the parts I recommend coventrywest.com, welshent.com, jaguarpartscenter.com, jagbits.com or jaggraveyard.com as they specialize in Jag parts.
You need to use the Jag factory parts.
jaguar parts center seems to be all mixed up. when i search for front suspension, the parts listed are only for rear. is there a part # XXXXX am looking for? also, i was told to replace the strut by non jag shop when i was getting an alignment. is this typical?
jagbits.com is the only one that seems to have the front air suspension...at a cost of $800. how do i determine if the suspension needs to be replaced.
Sorry for the delay. What kind of problem are you having and can I have the last six digits of your VIN'.
