How to replace rear axel seal on a 2000 ford mustang

Pull rear differential cover, remove small bolt/pin that holds pin in, remove pin, push axles in and remove both c clips, pull axles out and then remove seals....reverse procedure but ensure to fill diff with gear oil until it comes out the fill hole.

if your old rear end has good axles just swap them to the diff.with bent axles,hopefully thats not why you have to replace it in the first place,also replace the axle seals thay are probly bad from the bent axel

Its probably the left side, not only because you replaced the right side, but because it changes on right turns.
When you go into a right turn, the bearings on the left side are under more pressure and torque.
The front hub bearing goes bad more often than the axle bearing, so I would expect it to be the left front.

This is caused by a leaking rear axle seal you will need to pull the left rear axle out and change the seal and check for a worn axle bearing, this requires the removal of the differential cover, pin and center block or posi spring and clutch pack (if so equipped) and spider gears and then the "C" clip that retains the axle into the gear carrier, u will need a tube of silicone to reseal the cover and a axle seal installer tool and about 2 hours of your time

replace axle seals at the Diff.

do u mean the axle has "play" when u grab the tire and wiggle it up and down?? if it has play, then it propbably needs an AXLE SEAL AND AXLE BEARING.you will have to carefully inspect the axle itself where the bearing rides for any gouging or damage. THIS JOB requires a decent amount of mechanical skill. 1ST you need to remove the rear end COVER and drain out the gear oil into a drain pan.2ND remove the brake caliper and rotor . 3RD spin the" ring and pinion " around until u see a 5/16 bolt that passes thru from the pass. side to the drivers side. u have to remove this bolt. u will need to "hold "the gears from turning in order to break loose this bolt. 4TH remove this bolt and slide out the large metal ""PIN" that 'divides" the rear end in half. NOW CAREFULLY WITHOUT TURNING THE REAR END SPIDER GEARS,PUSH IN THE AXLE TOWARDS THE INSIDE SO U CAN REMOVE THE "C-CLIP" AT INNER END OF AXLE. now u can slide out axle and youll be able to replace seal and if needed axle bearing. let me know if u need more info.

You will need to remove the differential rear cover,drain fluid, remove wheel, brake drum, (rotor) . Unbolt center diff. pin, carefully remove (don't loose shims) push axle in remove lock keeper, then slide out axle, replace seal, put some grease on it, slide axle in reverse all to install.
