2010 Chevy Equinox. When making sharp turns as when parking into a parking space it vibrates or shudders from the rear or at least it seems to be coming from the rear. I have had it into my mechanic a couple of times. I did have a leaky power sterring pump which he changed. I have had new brake pads and rotors put on. Had the lube changed in differential with additive put in. Nothing is heating up. No noise going straight down the road. Only when turning it shudders or vibritates even with no pressure on brake pedal. At a loss

AWD? Did you check the rear axles? Try unplugging the fuse for the rear Diff module. If that solves the shudder, maybe the module or clutch pack.
It is an AWD. I will try that. If unplugging fuse stops the vibration or shudder can I just leave unplugged ?

I am sure you will see a warning light. It will only function as front wheel drive.
Will it hurt anything to run like that

I'm not sure.
Did this solve the issue? I have the same thing on my 2011. Its as if the rear is locked and not slipping on slow turns. Tires chatter.
I have 201 equinox AWD, which does the same thing when making sharp turns, I found out by removing fuse under hood, that it disables the ear drive, and the shuddering and popping goes away, (with fuse plugged in, it sounds and feels like the rear differential is locked in positive traction, if anyone has ever owned a vehicle with positive traction, you probably experienced this when it was locked in and tried to make sharp turns),
So something is calling for positive traction in the rear differential to be activated, not sure how or where the rear differential picks up the information from that calls for locking the differential?
Could be maybe a wheel sensor?
Looking at the rear differential module, has two plugs, one with two wires and the other with four or wires maybe, if the problem was in the clutch pack the problem wouldn’t go away when unplugging the fuse,
So that tells me that the module is bad or a sensor is bad, I’m not familiar with the inside of the rear differential, but I have read that it had a electrical coil that energized the clutch pack,
Anyone have any ideas on what or how the rear differential module picks up it signal from.
I did end up replacing the rear differential and that got rid of the problem. However I am curious as to what caused this. It is a new vehicle to me but has 54k miles on it, and I got a used diff from a local salvage yard. I have read and heard that changing tires on an AWD vehicle could cause issues with the differentials if the tires are not the same "condition" from one side to the others. Could this be the cause? But I don't know the history of the vehicle as I bought it from a small dealer, who told me he has had several other Equinoxes with the same issue.
Anyone got thoughts?

One thing I could think of. Maybe the previous owner had a flat and ran on the spare too long.
