1

Check temperature of rear axle differential.

 Only check and correct oil level in rear axle differential if rear axle differential is at room temperature.
Required oil may run out at a higher temperature, while at a lower temperature overfilling can occur. Both can cause damage to the rear axle differential.

If the rear axle differential is not at room temperature:



Wait until the rear axle differential has cooled down or warmed up to room temperature.

2

Clean area around the filling screw (50g).

3

Unscrew filling screw (50g) and allow any oil which may escape to drain into a suitable container.

4

Check oil level in rear axle differential.

 The oil must reach the lower edge of the threaded hole.

If the oil does not reach the lower edge of the threaded hole:



Top up oil to the lower edge of the threaded hole.
