Audible Noise - Chirping Sound but No Warning Messages

SOURCE: AWD acting like all wheels are locked up

  The clutch in the transfer case is burnt up and fused together therefor binding the powertrain. If you continue to operate it like this it will destroy the front differential and possibly the rear differential. It was most likely cause by the tires not having equal circumference either due to a mismatch of tires (different brands although the same size is indicated on the side wall will have different measurements,I have seen BF Goodrich tires have a different size because speed rating was different although the model was the same) or lack of tire rotation during the life of the tires.. If the measurements are not with in 1/4 inch around the center of the tread this will cause your concern. Tires should always be replaced at all 4 corners on all wheel drive vehicles.

Just had this same problem, starter was ticking but not turning, would start with jump leads but no sign of a flat or faulty battery. Garage I took it to replaced starter and alternater got £270 charge then when I got it back it happened again the next day!
Since found out that it was simply a dodgy connection between the battery and the starter.
