Whining Noise on XJR

We have a 1998 XJR that we just purchased - when decelerating from a higher
speed, we hear a soft whining or hum and then it goes away when
accelerating. Anyone else have this happen on this model - it is the
SuperCharged Jag - thanks

Re: Whining Noise on XJR

It could be a noisy rear end. Common complaint.

Re: Whining Noise on XJR

The rear axle has a large ring gear and a relatively small(er) pinion
gear. If their spacing isn't exactly correct their mesh will be "off"
and they'll be noisy at a specific speed, usually upon either
acceleration or deceleration. So if the noise always occurs at a certain
road speed, and usually in a 2 or 3 mph range, then it's probably the
ring and pinion mesh.

This can be corrected by adding or subtracting shims to move the pinion
gear ever so slightly forward or backward for perfect mesh with the ring
gear. There may be talk that the gears have already worn in and changing
their mesh is not advisable - that depends on the car's mileage -
because, yes they do have some wear now. The higher the car's mileage
the less advisable it would be to change anything.

Could be backlash in the compressor gears on the supercharger (think
blower Bentley) - quite normal & a 'feature'

I mean proper beer not that chemical Australian stuff ..

By "chemical Australian stuff", I presume you mean Fosters ? We Aussies
don't consider Fosters to be good beer either, that's why we export it to
other countries :)
