Rick, I never did get completely rid of the noise. Because the diff is right behind you and there is no insulation for noise, the sound carries and it makes you think it's actually the gears, u-joints, bearings ect.
I changed out all u-joints with genuine Jag parts (was living in the UK at the time) and had it set up with an ex-jag mechanic who was involved with Jaguars factory racing team at one time.
He said all the Jags IRS would make noise. Problem is, they were installed in big passenger cars originally and you never heard the disc noise.
Once I knew it was the discs/pads, it never bothered me again because I knew it wasn't anything serious.
Do you use your handbrake often. This can also bind and it takes time to relax.

Hope this helps
Mark
