Noise heard only when driving and from the rear area. Stops after driving higher speed and stays quiet after that. Sound is back again from cold start.

Will it do it when going around in a circle?I have seen moisture get in the rear drive module fluid and cause noises especially when making circles.

The chirping is still there when driving in a circle. It is the same loudness and chirps less often when turning left. It chirps when driving in neutral also.

When we recently took an hour and 15 minute trip the sound disappeared after driving 65 miles an hour about an hour into the trip and was quiet at slow speeds through town all the way home. The next day the sound was back. We can go for a half hour drive to town to shop and back and the sound is still there. We have not repeated the long trip yet to see if the sound goes away again.

Have you tried putting the rear end on jack stands and spinning the rear tires by hand to see if the noise goes away?I there was a campaign on those where they replaced the rear drive module insides and fluid was yours ever done?I will have to look it up and see we did a lot of them when I worked at the dealer.

My husband had the Vue on a lift at a local garage. All four wheels were off of the ground. This is an AWD vehicle and the front wheels rotated freely. The back wheels did not rotate freely all the way around. About after 270 degrees of rotation there was drag, about 45 degrees, and than it rotated freely. Both rear wheels did this. They figured that this might be normal for AWD? If not let me know, and if not what should the wheel rotation feel like?
They ran the Vue on the lift and could not hear any chirping sounds. Could this be because the wheels were not under load of the car? They feel that the noise probably is coming from the rear passenger CV shaft/axle at the differential. There seems to be about 1/16+" more end play and more shaft wobble on the rear passenger CV axle as compares to the rear driver shaft. The driver rear axle seems more firm with minimal end play and shaft wobble. They feel the early chirping is coming from the rear passenger CV axle? Your comments would be very helpful.

The rotation sounds normal I would try changing the rear end fluid make sure you use the correct fluid. Also see if the fluid looks white and milky really common for the fluid in those to get contaminated with water.

Will have the differential lubrication fluid changed in the next few days. What would be the normal endplay and CV axle wobble that's allowable for the rear CV axles? Thanks

Those axles really dont wear out often there not always having power to them. Only when there is wheel slip detected. Otherwise the axles are just a long for the ride and spin with the wheels. Your going to have some in and out of the joint play some float. Just not the side to side play which would be hard to see with the boot on the axle.

My husband checked the passenger rear CV axle again. When the output
hub on the differential is held in place( to allow minimal end play), moving the axle shaft up and down he could hear dull clicking sound coming from the CV rubber boot. The rubber boot has no leaks. He indicated that the CV boot end does move up and down. He still feels that the bearing inside the CV boot must have some wear, and is creating the chirping sound. Is also possible that the output bearing of the differential is worn too? Any additional comments. Thanks

The shaft is being moved manually up and down and is making noise. The noise is a chirp or click. Is it normal for the CV inner bearing to make any kind of noise like this when moved up and down? The passenger rear shaft when moved up and down moves very little if any motion and makes no noise? My husband says that grinding bearing noise normally happens when being rotated, this is vertical shaft motion up and down. Need you comments. Thanks

When your driving down the road the axles are spinning Iam not sure of specs of play etc. When I worked for saturn we changed the fluid the rear clutch pack assemblys and sometimes the seals.I have heard the seals making a chirp sound rubbing on the axle seal while spinning intermittently. Try spraying some lube on the seals like wd40 and see if it stops the noise at least temporarily.
