Jaguar XJ6 Rattling Noise Due to Failed Upper Front Shock Bushings
Jaguar XJ6 Problem
Average Mileage: 120,700 mi (69,000 mi - 175,000 mi)
Replaced the front shocks myself with some KYB's and problem gone. You can see it also if you just jack the car in front and look, shock itself (in my case) was bad where once raised the shock did not compensate and was away from the body at top. It should have expanded to fill the gap from jacking the car. This is evident after putting in new shocks.

I had that problem with the shock bushings too, I just added an extra washer Glued to the original ,
J B weld can also do the trick.
