Mysterious Undercarriage Squeak

Mysterious Undercarriage Squeak
Mysterious to me, anyway. 2004 XJR
Wife noted slight squeak when going over speed bumps, etc. When I got in car- no squeak. A week later we both noticed the squeak, especially if we had the windows down.
Yesterday, wife went on a 15 mi journey & it was very squeaky going; however, on the return squeak was gone.
The car is too low to the ground to get underneath while pressing up and down on the fenders.
Anyone ever have this same scenario? What was causing it?
Lifting shocks and air compressor all seem to be in good order

Mine gives a slight squeak audible from outside the car when pulling away, especially when cold. It sounds as if a brake pad is skimming the disc, but on jacking the car to investigate, it is actually coming from the propshaft area just ahead of the differential. Nothing is visibly touching anything that it shouldn't be, and I haven't narrowed it down more than that.

No Rain in 30 Days
Good point, Meirion. Since we haven't had rain in Seattle in 30 days, very possible. The noise doesn't bother me as much as my wife complaining about it.https://www.jaguarforums.com/forum/i...on_bowrofl.gif If I take a garden hose to it, where should I point it?

Yes, Meirion, discretion is the better part of valor.
With the help of the excellent folks on this excellent site, I have maintained and repaired this car since the warranty ran out many years ago; goodness, where have 13 years gone so quickly? I only take her to the shop for front end alignment and routine oil changes.
Back to the squeak: Pressing on fenders and center of bumpers produces no noise. Is there a way that I can tell what is causing the squeaking? I only have the capability of putting her up on jack stands; or, is this a project better left to the garage? Many years ago, I replaced 2 shocks and rebuilt the suspension air compressor(Thank you, Bagpipingandy!); both were relatively simple once diagnosed. Things like upper wishbone bushes, etc. are Greek to me; so, I would need some pretty detailed instructions.

I wouldn't necessarily rule it out. Those bushings can definitely wear out within 4 years depending on how much you drive and the condition of the roads around you.

Had a chance to drive the car this morning &, at first, you would think that the squeaking is coming from underneath the front seats. So, it is my guess that it is something from the front seats or towards the rear. I will endeavor to look at a diagram today, my best thought is that it is the rear upper wishbone bushes as previously mentioned. We have still had no rain; however, we've had long periods without rain and there has never been any squeaking.
Since I haven't found any ways to diagnose, I will make an appointment with the frontend guys.

Right front "Hind Joint"
"Right Front Hnd Joint"
Suspension guy says the joint is sold as a unit & runs over 1,000 US with tax; labor would be $550.00. OUCH!
However, we've been customers for 30+ years and he is going to try some silicon lube since there is not a safety issue; the bolt is solidly intact.
He says that there is no indication that the left is in anyway deficient.
Is replacing this joint something I can do? I have replaced a shock, brakes, etc. How long would it take? Is there an alternative to purchasing the entire arm?
Thanks for your help.

Me either, XJ8JR.
I will take this diagram with me when I go to pick her up to get it identified.

Could he have said "High" or some other similar sounding word?
If I had to guess, it is the upper arm in the diagram, most visible on the right.

Ok, so I'm guessing its this one, since they're talking about the strut mount point:
More Information for MAS CA24024
I replaced both sides a few months ago. It is possible to replace just the bushings, not the entire arm, which could save you a couple of bucks. Removal of the arm is pretty straightforward, except for releasing the balljoint taper. If you're lucky, a balljoint separator will do the trick, but one side on my car had somehow become fused together and took the inner sleeve completely off the control arm (luckily I was replacing the entire arm anyway). You'll most likely need your alignment redone afterwards as well.
The Jaguar branded arm will cost near $1000, but I see no issues with using these arms from Rockauto for around $175.
