INCLINOMETER INSTALLATION ON REAR KNUCKLES
(1) Clean any dirt or debris off knuckles paying
special attention to caster pads on trailing end of
knuckles near ball joints.
NOTE: Do not attach inclinometers to rear Adapters
before Adapter installation on vehicle. If attached,
they cannot be installed or removed with rear
wheels on vehicle.
(2) Insert each Caster Angle Adapter (without
inclinometer attached), Special Tool 8996, through
opening between upper control arm and toe link.
Position Adapter lower spring-loaded hook over lower
ball joint machined casting and upper spring-loaded
hook around upper ball joint nut, then stretch
bracket rearward, placing Adapter flats against
caster pads cast into trailing side of knuckle (Fig.
20).
(3) Mount inclinometers to rear Caster Angle
Adapters (Fig. 20) (Fig. 21). Make sure inclinometer
from left side of Switch Box is mounted to left
adapter and inclinometer from right side of Switch
Box is mounted to right adapter. To make sure each
inclinometer is mounted right-side-up on Adapter,
upper mounting screw is larger diameter than lower.
