Low rumbling sound from rear end when car warmed up
I've started to notice a low rumbling sound that seems to be coming from the rear of my XJR. It seems to start after 20 minutes of city driving and is most prominent at acceleration and when turning.
Wheel bearing? Rear diff? Exhaust system loose? Bad gas?!
Seriously any ideas before I get a change to get under it?

Wheel bearing problems are not unusual on X300s. Nor are diff problems, for that matter....but not as common as wheel bearings.
You may have to get the rear wheels off the ground and listen for the noise with a helper working the throttle. Be careful!
However.....
In the last year or so the exhuast has become louder on my XJR. No holes anywhere.....it simply has a rumble that wasn't there before. Not obnoxiously loud, but it's there

Agree with Doug.
Mine developed that similar described rumble, and also only after 15-20 minutes driving.
It is not an "R", just a lowly 3.2 XJ6.
Turned out to be tyres. Furthest thought at any time, but some new rubber, SILENT.
I went thru centre bearing, wheel bearings, exhaust etc, and finally some wheels from a mates XJ8, just for giggles, found ya.
Doug, my 3 Jags have that exhaust "drone" sound, that was not there when we first got them. My "scientific" evaluation is that we drive these cars MUCH harder than the previous owners, so all that gunk in the exhaust etc has been blasted out, and the Jag rumble is what is left.
My Black S Type has started the same rumble, and worn Pirelli's are my first thought.
