Transverse Link and Lower Ball Joint
REMOVAL AND INSTALLATION
lRemove tension rod, ball joint and transverse link assembly.
lDuring installation, final tightening must be done at curb
weight with tires on ground.
lAfter installation, check wheel alignment.
Refer to ªFront Wheel Alignmentº, ªON-VEHICLE SER-
VICEº, FA-6.
INSPECTION
Transverse link
lCheck transverse link for damage, cracks or deformation.

Replace transverse link if necessary.
Lower ball joint
lCheck ball joint for excessive play. Replace transverse link
assembly if any of the following exists:
lBall stud is worn.
lJoint is hard to swing.
lPlay in axial direction is excessive.
Before checking, turn ball joint at least 10 revolutions so that
ball joint is properly broken in.
