i have an ap1 .... basically i had this screeching / creaking noise for a while now ( rear driver side ) ....

it makes the noise on acceleration, then lightens up on deceleration, even while rolling in neutral it still has the noise...

took it to a shop just yesterday and he told me that my differential needs to be replaced, Could it be ?

ive already changed the wheel bearing, any other possibilities ?

any ideas ?

 

Check the mounts,re-torque the axle nuts to 220lbs

 

Sure does sound like a wheel bearing. :/

Does it make the noise on jack stands? Be safe, but try and pinpoint the noise. Shouldn't take but a second to find it.
