CAMBER READING (Laser 4 Plus)
Camber: The inward or outward tilt of the wheel at the top
Camber is measured in degrees.
Wheel exactly vertical: Zero camber
Top of wheel tilts in: Negative camber
Top of wheel tilts out: Positive camber
A vehicle with Negative Camber is shown in Fig. 10.
Proceed with the following steps to read Camber:
1) Place front wheels in straight ahead position with
steering wheel level. The engine must be started if the
vehicle has power steering. Remove locking pins
from the turning radius gauges and rear wheel slip
plates. Rotate each wheel until the large wheel clamp
adjusting knob is at the top.
2) Lower all four wheels until the front wheels rest on
the turning radius gauges and the rear wheels rest on
the rear wheel slip plates. Be sure turning radius
gauges are centered under the front tires.
3) Install brake pedal depressor. The engine must be
running if the vehicle has power brakes.
4) Bounce the vehicle at both front and rear to normalize
the suspension weight.
5) Mount the Electronic Gauge on the left front Wheel
Clamp. Be sure the magnet is centered on the
mounting disk (See Fig. 11).
6) Set the selector to CAMBER and press the switch to
ON (See Fig. 12).
7) Read Camber on the Digital Readout Scale (A
negative 0.3 is indicated in Fig. 12). The numeric read
out will be preceded by a + or - to indicate positive or
negative Camber.
8) Repeat the above procedure on the right front wheel.
If camber adjustments and specifications are available
for the rear wheels, repeat the above on each wheel.
