Essentials to the removal of piston rod nuts
Warning:
It is dangerous to remove the piston rod nuts. The
shock absorber and helical spring may pop up under
the effect of powerful pressure and cause serious
personnel injury and death. Prior to the removal of
piston rod nuts, be sure that the shock absorber is
installed inside the SST.
1. Protect with a piece of fabric, the helical spring,
and then install the SST.
2. Use the SST to compress the helical spring and
remove the piston rod nuts.
Essentials to the installation of helical spring
1. Install at first the lower rubber mat of helical
spring on the shock absorber;
2. After the helical spring, stop block, dust cover,
upper rubber mat of helical spring and upper
spring seat have been placed in a proper place,
place the bearing on the upper spring seat and
put in the upper support of shock absorber；
3. Protect with a piece of fabric the helical spring
and then set up the SST.
4. Compress the helical spring by use of the SST.
6. Install the shock absorber and be sure that the
opening of helical spring is aligned with the
stair of spring seat retainer on the shock
absorber and the hole on the upper spring seat
aligned with that at the outer edge of lower
spring seat on the shock absorber.
7. As shown in Fig. install the upper support of
shock absorber and piston rod nuts and then
remove the SST;
Tightening torques of piston rod nuts:
78.4-109.8 N.m {8-11.2 kgf.m, 57.8-81 Ft.lbf}
Statement:
1. Align the positioning mark point on the upper
support of shock absorber with the rear
direction inside the bodywork mounting
location and then install the shock absorber.
Essentials to the installation of front damping
column assembly
The upper support of shock absorber uses different
colors of positioning mark points as the function to
prevent the error in the R/L installations (Green to
the left; white to the right). In the installation, be
sure that the positioning mark point is located inside
the rear direction to assure that the parameters of
4W alignment have not larger deviation.
Check of front damping column assembly
1. Remove the front damping column assembly
from the vehicle;
2. Check whether there is any appearance damage
and any oil leakage on the shock absorber.
3. Check whether the lower rubber mat of helical
spring and upper rubber mat of helical spring
are ageing and worn.
4. Disassemble the damping column assembly.
5. Compress and stretch the shock absorber piston
for at least three times and confirm that the
