How to check rear diff oil level

[A7788]

Hello boys and girls,

Noticed one side of the rear diff is leaking oil - not massive amounts but as I only got the car recently I don't know how long it's been going on for. How do I check the oil level for this?
Also how difficult is it to replace seals, etc?

Thanks!

Open the filler plug first and top it up with genuine oil. Seals are easy to change but you need to remove the RH side driveshaft. Car must be level so you either have it over a pit or on the ramp/axle stands.
