Urgent replies needed DIFF OIL + refresh

[totta Crolla]

The oil will drain better if it is hot but be careful not to burn your
hands on it.
I usually warm up the new oil by standing the bottle in boiling water
for a few minutes, makes it a lot easier to fill.
If you are using bottles with long plasic spouts on then you will
need as much space above the diff. as possible so it is best to
put the chassis on stands and let the axle drop as low as
the dampers will allow.
