20 When reassembling, pack the joint with
special FIAT Tutela MRM2 lubricant; if this is not
available, use molybdenum disulphide grease.
21 The reference groove on the outer track
must be assembled so that it is towards the
final drive when refitted (photo).
22 Pack the joint and the inside of the boot
liberally with the specified grease.
23 If a new joint is being fitted to the shaft,
make sure that the joint and shaft colour
codes match.
Shaft colour Joint colour
Blue Blue or white

Right-hand driveshaft damper
weight (1108 cc and
1372 cc ie models) -
removal and refitting #
24 A damper weight is fitted to the longer,
right-hand driveshaft to reduce vibration (photo).
25 It should not be necessary to remove the
damper weight unless the driveshaft is to be
renewed, or the weight has been damaged.
26 The weight is in two halves, and can be
removed by simply unscrewing the two clamp
bolts securing the two halves to the
driveshaft. Note that the weight locates on a
rubber mounting which is split along its
length, and can simply be pulled from the
driveshaft for renewal if necessary.
27 Refitting is a reversal of removal, but
ensure that the damper weight is positioned
exactly as shown in Fig. 13.101.
14 Braking system
PART A: BRAKING
SYSTEM - GENERAL
Front brake pads - all later
models
1 The front brake pads have modified
anti-vibration plates and a wire spring fitted to
prevent them from vibrating and knocking in
operation.
2 On some models the clip securing the disc
pad locking block is located on the inboard
end, rather than the outer end (shown in
Chapter 8). To ensure correct reassembly,
check the location of the original block
retaining clip before dismantling the brake
unit. The alternative fixing arrangement is
shown in the accompanying photos, in this
instance on a 1372 cc ie model (photos).
PART B: BRAKING SYSTEM
- TURBO IE MODELS
Description
1 Disc brakes are fitted to all four wheels on
the Turbo ie models. The front disc brakes are
of different design from those used on other
models, in that the wear in the pads can be
checked without the need to remove the
caliper cylinder housing.
Front disc pads - renewal
2 Raise the front of the car and remove the
roadwheels.
3 Check the thickness of the friction material
on the pads through the aperture in the caliper
cylinder body. If the thickness of the material
is 1.5 mm or less, then the pads on both sides
must be renewed (photo).
