Danger of causing damage to the differential.

• Slowly remove the differential from the transmission housing. Otherwise differential can fall out of transmission.

• A differential that has fallen out can no longer be installed. If differential falls out, the transmission must be replaced.

• Make sure the differential bearing race/tapered roller bearing and adjustment shims do not fall out of the transmission housing and final drive.

• Bearing races/tapered roller bearing and adjustments that have fallen out cannot be allocated with shop equipment.

- Carefully remove the differential - arrow - and lay it on a soft support.

There is a risk of damaging the transmission.

• There are different gear oils for the "0AW transmission".

• Only gear oil available as a replacement part meant for the transmission code may be used.

• Do not mix the axles oil, not even in small quantities. This will cause the sealing rings to leak. Note the allocation of the axle oils according to the transmission code letters. Refer to the electronic parts catalog ETKA. Only axle oil for "0AW transmission" which can be obtained as a replacement part must be used in front final drive.

• Replace the filler plug after checking the level. Always pay attention to the allocation according to the transmission codes in the electronic parts catalog ETKA. Compare the old and new filler plug to prevent leakage on the transmission.

• Do not mix other gear oils, even in small quantities. Leaks in the transmission will result.

- Fill the gear oil in the front final drive after installing the transmission and check the level.
