Suspension
Check Front Suspension
1.Check condition of all ball joint dust covers,
including anti-roll bar links.
2.Check tightness of all accessible suspension
fixings including tie rods.
3.Check wheel bearings and suspension struts
for signs of excessive play or wear.
4.Check track rod ends for wear by attempting to
move the joint forwards and backwards, side to
side and up and down. No wear should be
apparent, if any is detected then the joint must
be replaced.
5.Check for signs of leakage from suspension
dampers.Check Rear Suspension
1.Check tightness of all accessible suspension
fixings including transverse links.
2.Check wheel bearings and suspension struts
for signs of excessive play or wear.
3.Check for signs of leakage from suspension
dampers.
Check Tow Bar Fixings
1.Check that the two vertical fixings are tightened
to a torque of 110 Nm (82 lbf.ft).
2.Check that the six transverse fixings are
tightened to a torque of 60 Nm (45 lbf.ft).
