I added the additive from Jaguar and followed the instructions, including measuring oil temp. the noise was still there, so i repeated the heating process and the noise was still there, drove it next night and it has all but dissappeared, a note on mine was it was worse when the fluid had warmed up, i don't think it has gone completely, if it is the pinion seal i wander how difficult it is to replace, and if that will cure it?

Jaguar have a part number for an additive to add to the power steering fluid as they are aware of the squeaking issue. You just remove some of the existing fluid in the reservoir and add in the additive. Then you run the car and get the steering fluid at temperature and get the fluid fully through the system by turning the steering from full lock to full lock a few times. I did this on mine and the squeak took about a week to fully disappear. I did this nearly a year ago and it's been completely silent ever since. I'll try to dig out the additive part number.

I had the same problem with my wife's 04 XJ8. The special fluid added to the power steering did work after I cranked the wheel all the way to the left without putting a lot of pressure on it. Then crank it all the way to the right and hold it there while increasing the engine RPM. Do this a few times to the left and right. Try not to put a lot of pressure left or right. Just gently hold the wheel to its limit both ways while increasing the rpm some. A jag specialist gave me this info and it did work. Hope this helps. Make sure you don't crank the wheel hard at its limit while increasing the RPM. It could blow your power steering pump.

I will be ordering up some of the additive, currently $27 on Amazon, as our new to us 2004 XJ8 makes a quiet, but noticeable noise on turning the wheel.
Initially thought it was the clockspring or something rubbing, so swapped it with the one on the parts car that had been quiet and the noise is still there.
There are related issues as well - horn only works if you press the top of the airbag cover, not the bottom, and the lights come on once the key gets to position II no matter what the light switch is set to.
Swapped the light switch over too, but no change there either.
Noticeable was that while both 2004 models, one has two rings on the wheel that contact two points on a switch attached to the bottom of the clockspring. Think this is horn related, luckily both clocksprings had the mountings to take this switch assembly.

This is not a steering column, not a rubber seal, or a power steering pump! The steering rack squeaks. In the place where the steering column shaft joins. I went through this. Lubricated everything, the column, the seals, everything was useless. The issue was resolved by replacing the steering rack.
