General
Never work under a vehicle with air suspension, which is not fully secured against
falling, in case there is a change of pressure in the air bellows. There is a risk of getting trapped and injured. Both the chassis and moving axle suspension components
must be secured against falling with axle stands to ensure absolute safety when working under a raised vehicle.
Use protective goggles when draining oil. Oil can spray out at high pressure if the
rear axle housing ventilation is blocked.
Work description
General
1. Take the load off the axle housing before removing the central gear.
2. Trucks with leaf spring suspension must be supported under the frame or springs
as illustrated.
