Torque spec for fill and drain bolts is 60 Nm or ~44 ft/lbs

Reinforcement plate bolts should be replaced with new and torqued to 54 Nm or ~40 ft/lbs and then a 90 degree rotation

Important!
If oil is filled up to the lower edge of the oil filler opening, the front axle differential would be overfilled and in rare individual cases oil could emerge from the ventilation opening on the front axle differential.
After draining front axle differential oil or when carrying out the initial filling of a new replacement front axle differential, the transmission must be filled with 600 ml oil.
Only use the approved front axle oil in the front axle differential.
Failure to comply with this requirement will result in serious damage to the front axle differential!

Note:
Only change oil when front axle differential is at normal operating temperature.
