The noise is not coming from the pinion seal, but the pinion bearings are bad and this is why the pinion seal is leaking. You will need to have the rear end bearings and seals replaced. If you'd like to have this verified, a certified technician from YourMechanic can come to your car's location to diagnose the squealing noise and assist with repairs.
