2002 Ford Think Sqeaking noise...

I have a squeaking / squealing sound coming out of the I’m assuming it’s the gear case that come out of the back of the car. Any idea how to fix this or would I would need to fix it? There’s really not a lot of information on Ford thinks

If it only squeaks when moving try jacking up the back wheels off the ground and spin them to see if it makes the noise. Could be a dry u-joint, bad bearing or a dry seal
