 Hi All

i am hearing a rumble from back of car with hood up i am thinking it could be wheel bearings

when hood is down i do not hear it any ideas ?

 Wheel bearings give more of a whine when they start to go. Have you checked that you have oil in the diff?

 …and when did you last change your diff oil, using a good synthetic of course.

Put your trolley jack under the diff (using a piece of wood to protect the casing), jack the car up so that both road wheels are clear of the ground and spin the wheels, rock the wheels from side to side etc and see if you can hear anything funny.

Happy hunting.
