Applying solid oil or its mixtures for lubrication of the needle
bearings can lead to their premature failure.
Do not apply too much grease to the splines as it will bleed
through the spline coupling, resulting in premature failure of
the oil seals and possible plug knocking out of the slip yoke.
Use a special tip on the grease gun to lubricate the knuckles.
The motor vehicle may be equipped with non serviceable
propeller shafts (without grease fitting). If this is the case,
regularly check shaft coupling pleated sleeve. Following pleated
sleeve damage, apply to the service centre for replacement.
Driving axles
Check the oil level in the housing, it should reach the lower
edge of the filler orifice.
Drain the oil through orifice 2 (Fig. 9.24) at the bottom of
the housing by screwing out filler plug 1.
Axial clearance over 0.05 mm in the bearings of the axle
drive pinion is not permitted, as greater clearance would provoke
premature gear teeth wear and that could result in an axle jam.
Check the axial clearance in the bearings by swinging the drive
pinion by universal-joint flange.
Axial clearance in the differential bearings of the final gear
is not allowed. Check the clearance by swinging of the drive
pinion when the housing cap is removed.
If an air gap is detected, the axle should be adjusted. The
axle adjustment is a labour-intensive operation requiring specific
skills and instruments, that is why we recommend to conduct
the axle adjustment only at a service station.

1 — filler plug; 2 — drain plug; 3 — safety valve; 4 — lower pin nut
