I have all the bolts out and the differential can be lowered on the driver's side but it's not breaking loose on the passenger side from the cup the differential mount hangs from. I can shift the differential left to right about 3./16 of an inch and can move the differential up and down in the cup about an 1/8", but it still won't release. Has anyone experienced this and knows how to release the differential? I don't want to put too much pressure on the axle casing prying it loose as I'm afraid of breaking the casing.
