Hi all, Now i got the audio problem out of the way, as the title suggests ive got an intermittent noise coming from the rear.

Very difficult to describe, but it sort of sounds like somethings rubbing and when it occurs it seems to put resistance on the wheels and cause the box to change up! I haven't had a chance to get under the car yet and have a poke around, but i have seen plenty of references to this kind of thing on google. It only seems to happen when maintaining speed. There is no noise or sensation when under acceleration or braking.

Without looking, anyone had any kind of experience with anything that sounds remotely like this?

Might be worth checking the rear brakes for any binding etc.

Jack rear wheels up securely, set traction control off, run the car in drive so the rear wheels are spinning, listen for any rubbing from brakes. If excessive rubbing noise it could be sticking calipers.
Turn off engine, remove brake fluid resovoir cap. Gently pry the inner pad away from each disc with a flat screwdriver, ie pushing the caliper pistons back in. Repeat car running in gear. If noise is reduced it would point to the caliper(s). While running apply brakes on and off, compare any noise after braking etc.

 

it could also be a parking brake fault - a loose shoe/spring or dragging shoe, so if the above tests don't identify it, you may need to remove each rear caliper and disc to get at the parking brake internals. Are the discs excessively hot after this occurs? an infra-red temp gun is advised here....either way, something's sticking on the rear brake system and needs checking.

 

Many thanks for the advice chaps. I'm keeping my fingers crossed its nothing more serious than a caliper or shoe prob and if so, easily fixed.

As soon as i get a chance to get her up in the air (no pun intended), and have a look, will report findings and get some pics while im at it. Given that im new to jags, and don't ever envisage owning another make of car, is there anything else i should be paying particular attention to while im under there?
