JAGUARS-TYPEChassis
54The centre joint is a conventional hookes joint
with staked lugs and the rubber flex couplings
have spigoted sleeves to the transmission and rear
axle final drive unit (three bolt fixings)
All driveshafts are balanced. If undercoating the
vehicle, protect the driveshaft, universal joints
and the axleshafts to prevent overspray of the
undercoating material.
Driveshaft weight is:
¥ V6 auto 12.7 kg
¥ V8 auto 13.4 kg
¥ V6 manual 14.1 kg
Serviceable parts are the centre bearing, flex
coupling, rubber boot, alignment bearing and
fasteners. Lubrication of the driveshaft
components is unnecessary. The universal joint is
equipped with nylon thrust washers, located at
the base of the bearing cup.
Balancing of the driveshaft is achieved using a
PDU with the new vibration analyser. This gives
details of where the shaft is out of balance and by
how much and where to place the balance nuts.
Final Drive (differential)
The final drive, differential, has a steel case and
rear cover, no drain plug and has a sealed for life
lubricant. Differential weight is 27 kilograms and
oil capacity 1.5 litres of synthetic oil (M2C192A).
The hypoid gearset is mounted in taper roller
bearings. It has a two point differential assembly
retained by bearing straps. The central pinion is
on the body centreline. Pinion and output oil
seals, the companion flange and nut and the
needle roller output bearing are the only
serviceable items.
Final drive ratios are:
3.31:1 (V6 and V8 auto)
2.87:1 (V6 manual)
Differential Mountings
The crossbeam forms the mounting points for the
three differential mounting bushes. All three
bushes are conventional rubber bushes, common
to all S-TYPE vehicles and are serviceable items.
They control the driveline and isolate differential
noise and vibration. Avoid disturbing the subframe
mounts when servicing differential bushes. The
front differential bush is a two-part bush and the
RH and LH rear bushes are handed and colour
coded to differentiate them
Half-shafts
Half-shafts are unequal lengths and are therefore
handed, left and right. Constant velocity joints are
fitted to both ends, the outer is fixed and the
inner is sliding. They are sealed for life and
retained in the differential side gear with a spring
clip.
Weights are approximately
V6 size - 100 8.89kg (LH) 8.76kg (RH)
V8 size - 104 9.43kg (LH) 9.3kg (RH)
Serviceable parts are:
¥ the pinion and output oil seals
¥ companion flange and nut
¥ output bearing (needle roller)
Note: It is possible that the replacement or repair
of gears, bearings or shafts may be introduced at a
later date.
