Driveline
Introduction
The driveline is a standard type with the engine
position at the front and driven rear axle. This will
be the first time that Jaguar has used in-plant
driveline balancing to improve noise, vibration
and handling. The driveline is finely balanced at
the rear driveshaft joint. The centre bearing is
laser aligned during initial factory build.
The alloy rear engine mountings have two
variants, one for automatic transmission and one
for manual transmission. They are both
serviceable items. The V6 auto is the same as the
V8 but rotated in plan by 180 degrees. The rubber
mountings are carry over concept from the
current XJ and XK Series vehicles but are not

DRIVELINE ARRANGEMENTinterchangeable with them. Both automatic
transmission rubber mountings are common but
with a softer unique mount for the manual V6
transmission.
In service if they are replaced, ensure that there
are buffer gaps and that they are approximately
equal. Neither will be contaminated by lubricant
or automatic transmission fluid.
Driveshaft
The S-TYPE has a two-piece welded steel tube
driveshaft with a splined centre slip joint and
locking collar, the whole being aligned with the
body centreline. The driveshaft has rubber flex
couplings and a rubber, body-mounted, centre
bearing. For safety, the front tube is collapsible.
