My rear diff as been leekin a tiny bit since I got the car over 3 years ago. It was not leaking much at all, no drips or anything just making the diff damp. But thought I would change it anyway.
Here is the diff before I started.
Getting the old seal out.
New seal and a pic next to the old one. Can see its quite worn.
Also got home to find my new tyres had arrived for the powdercoated alloys so went and got them fitted.
