Checking the oil level in the differential
The oil in the rear axle differential housing does not need to be replaced. The oil level should be checked every 20,000 km.
Take the vehicle for a short drive to allow the differential housing oil to reach normal operating temperature.
Raise the car and support it.

Unscrew the filler plug (left arrow) using a socket wrench SW 14.
The illustration shows the differential for models produced after February 1981. The right arrow points to the drain plug.
A slow flow of oil from the filler hole indicates the correct level. In case of doubt, check with your finger whether the oil reaches the lower edge of the hole. If the oil does not reach the lower edge of the hole, add oil using a pump or syringe.
Note: If there is excessive oil consumption, the cause should be determined and eliminated.
Oil type: Hypoid-Geai Oil SAE 90. Use the oil recommended by the manufacturer.
Note: Transmission oil has a fairly thick consistency, so it should be added in small portions. taking breaks. A tray should be placed under the differential to collect spilled oil.
Tighten the filler plug.
Checking the drive shaft casings
Raise the car and support it.
Inspect the casings and surfaces near them for traces of grease.
Check the reliability of the clamps.
Using a lamp, inspect the rubber for cracks. Cracked casings must be replaced.
If the casing is pulled into the hinge by a vacuum or has other defects, the casing must be replaced.
Checking the oil level in the self-leveling system
On models equipped with self-leveling rear suspension, the oil level should be checked every 20,000 km with the engine off.

Remove the dipstick (2a), wipe it with a clean cloth and reinsert it.
Remove the dipstick again and check the oil level.
When the tank is full and the vehicle is normally loaded, the oil level should be between the maximum (b) and minimum (c) marks on the dipstick.
When the machine is fully loaded, the oil level should be at the minimum mark. If necessary, add oil using a funnel and a narrow tube. Use only the oil recommended by the manufacturer.
The difference between the minimum and maximum oil levels is approximately 0.6 l. The total capacity of the hydraulic system is approximately 3.5 l.
