WARNING! Transfer case ‘Dymos’ malfunction signal device
turns on after switch starting and turns off when the system
in normal condition. When signal device is turned on, go to the
nearest authorized service center for four-wheel drive check up.
Propeller shafts
Regularly check threaded couplings (see Annex 2).
The spline coupling is lubricated through grease tting 1
(Fig. 9.14), which is screwed into the slip yoke, and the needle
bearings are lubricated through grease tting 2 on the crosses.
Lubricate the needle bearings until the grease shows up from
under the working edges of the cross oil seals.
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 splined couplings, as it
would bleed through the spline coupling, and that would provoke
a premature failure of the oil seals and could eject the plug of the
slip yoke.
Use a special tip to be tted on the grease gun to lubricate
the knuckles.
