aThe seal (gearbox side) is made by pushing the gai-
ter lip (9) into its housing on the gearbox, moving the
flange (8) .
Wipe oil from:
-the flange (8) ,
-between the flange and the gaiter,
-the seal lip (9) ,
-the face of the lip on the gearbox.
Refit the driveshaft on the gearbox side (this opera-
tion requires two people):
-Person 1:
•position the driveshaft at the differential input,
•fit the flange (8) on the gaiter (7) ,
•fit the driveshaft into the gearbox whilst keeping
the flange (8) on the gaiter,
•push the flange (8) to insert the gaiter lip (9) in its
housing (do not pinch the gaiter (7) ).
-Person 2:
•tighten the 3 flange mounting bolts (8) but do not
tighten fully (the flange should still be loose).
-Person 1:
•keep the driveshaft as horizontal as possible (with
respect to the differential).
-Person 2:
•torque tighten the flange mounting bolts (21
Nm).
aFit the front left-hand driveshaft into the stub axle
carrier.
aRefit the bolts to the shock absorber base.
aTorque tighten the shock absorber base bolts(105 N.m).

aFill the gearbox (see 21A, Manual gearbox, Manu-
al gearbox oils: Draining - Filling, page 21A-2) .
aRefit the engine undertray. WARNING
To ensure a correct seal when refi tting a gaiter to
a gearbox:
-the flange (8) must be fitted to the gaiter (7)
(see figure 107922) in order to support the seal
lip (9) and to fit it correctly into its holder on the
gearbox.
Note:
The driveshaft must fit freely into the stub-axle
carrier until it protrudes enough for the hub nut to
be fitted.
