Methods of detection of the front suspension spring precipitation
The springs should be removed from the vehicle in case of breakage or when
considerable sediment, or one of the two springs.
Draft springs on the car checked for gaps between the buffers
compression on the lower wishbone suspension and the crossbar in the areas of xcontact
In the case of precipitation of one side of the car, determine what
is the cause of subsidence, as in the front of the roll
subsidence affects the body of the elastic element rear suspension.
To carry out the work, set the car on a horizontal
area and measure the height difference of similar points
located on centers of lights on the left and right sides.
The measurement is made after swinging the front end
a spring suspension.
On the heel of the supporting hydraulic jack installed support
prism (Fig. 129), with its fixation on the two holes on the bottom
cross the plane of the suspension (Fig. 130) and rises
front end to the separation of the front wheels.
Next, the re-definition of the difference up to the heights of points
previous measurements. When measuring the difference in heights
preserved in both measurements, ie the car is constantly tilted
on one side - slipped spring rear suspension on the side of
lower height. If the initial measurement of the slope of the vehicle
in one direction, and when measured at the reference prism car
aligned and there is the inclination in the opposite direction -
subsided spring front suspension on the side of a lesser height to
center in the measurement of car headlights on wheels.
Suspension springs are removed after removing the shock absorbers and
disconnecting front stabilizer of the lower arm.
For ease of execution of works to prevent accidental
injury in the spring blossom should be used
clamping device for spring (Fig. 131).
