Roaring when I decelerate

not wheel bearings or diff bearings?
long shot - mine made a horrible drown when decelerating from above 60km/h - it was the driveshaft hanger bearing. quiet below 60km/h, it sounded like truck engine brakes above 60km/h, and caused a harsh drivetrain.
get a mechanic to run the car up in the gears, up on the hoist... or do it yourself on axle stands if you're feeling keen.

Gotta check this info with those of you that are experts.
The mechanic that used to work on my car says I can drop a rear differential from an XJ6 into my XJR with no problems.
The lack of limited slip won't affect anything, he says. In fact I have never really been a big posi-track fan.
He also says it may improve my gas mileage as the gearing changes (to exactly what Doug said).
Can I just drop it in and go?
I am guessing it will affect the speedometer and what of the "traction control" button/light?

Going from a 3.27 to a 3.58 will reduce fuel econonmy by about 1 mpg at freeway speeds. I know, because I've done it . I didn't notice any change in city fuel economy.
The speedo runs off the left rear wheel speed sensor so you don't have to worry about your speedometer readings.
And, yes, you can go with non-limited-slip. I was lucky enough to find a 3.58 limited slip....but if you don't care, the car won't care, including the traction control system
