(3) Next, grasp end of transverse link and move it up and
down. Relative movement between housing and transverse
link boss indicates ball joint may be excessively worn.
(2) When looseness is less than standard value, wipe off
old grease, apply the proper amount [about
3
g (0.11 oz))
of designated grease (SUNLIGHT 2, PIN 003602010),
and install a new dust seal.
When transverse link ball joint has been removed or replaced,
check toe-in (or side slip) of front wheel.
If front wheel toe-in (or side slip) is not at specified value,
adjust according to chapter 4·1 so that toe-in conforms to
service standard.
3) Wheel alignment and ground clearance ...... Inspect
every 48,000 km (30,000 miles) or 30 months, whichever
occurs first.
(1) Unload cargoes and set vehicle in curb weight
(empty) condition.
(2) Then, check ground clearance of front and rear
suspensions to ensure that they are within specified
values.
(Adjusting procedure)
When ground clearance is out of standard, visually inspect
following components and replace deformed parts .
• Suspensions components [Front: strut assembly, cross-
member, transverse link, etc. Rear: shock absorber,
inner arm, outer arm, etc.]
• Body parts to which suspensions are installed.
When no components are deformed, adjust ground
clearance by replacing coil spring in the suspension whose
ground clearance is out of standard.

deformed parts.
• Suspension components [Strut assembly, crossmember,

• Body parts to which suspensions are installed.
(b) When toe-in (or side slip) is out of standard value,
adjust by the method described in chapter 4-1 so that it
conforms to service standard.
(c) When right-and-Ieft turning angles of tire are out of
standard, adjust to standard value by method described in
