Hi everybody! I have just come home from work and whilst going around a slightly downhill and slight righthand bend,I felt the rear kick slightly! A few moments late a noise like a wheel bearing started! So I got the wife to drive(yes, she is given permisson sometimes) and the noise is from the rear diff area! Could this be the diff or the Awd unit? The noise sound like at grating bearing! It start's as soon as you move off and get's faster until it goes at around 50 mph! Being new to the AWD ,I don't know anything about this system,other than it is like the VW syncro system! Any idea would be helpful!!! Thank's
