What causes a differential to leak in a mustang?

Generally it is the pinion seal(where the driveshaft attaches). On a high mileage vehicle a groove can be cut in the sealing surface allowing a leak to start. When it is taken apart, the sealing surface should be looked at carefully. If it is worn a 'SLEEVE-N-SEAL' ( FELPRO COMPANY)can solve the problem.......1930fcoupe It could very well be the pinion seal, or the differential cover gasket, depending on if the fluid leak is coming from the front or rear of the differential.

What would cause a grinding noise from the rear-end of a 1997 Mustang GT It sounds as if it is coming from the differential housing but could it be the axle bearings in the rear-end?

It could be axle bearings, however it is more likely a pinion or carrier bearing since you say the noise seems to be coming from the differential housing. With the vehicle up on a lift around 45 mph, use a mechanic's stethoscope to help pinpoint the noise. You should be able to at least determine if is coming from the axle bearing or the differential, sometimes you can tell if it is a pinion bearing (noise more pronounced near the driveshaft) or if is a carrier bearing (more pronounced near the rear cover).
