ings. Stroke shocks at various
rates of speed through maximum
travel in both directions . Compare
side to side for rebound and com-
pression resistance . Rebound re-
sistance is normally stronger than
compression (approximately 2 to 1) .
It is manadatory that right and
left shocks feel comparable . If
in doubt about condition, compare
with a known good shock .
SHOCK ABSORBER- l . Loose mounting.
l . Check all shock mounting torques

(bolt and/or nut) .
2 . Faulty shock absorber .
2 . Observe hoisting instructions and
instructions for removal of front
shock absorbers. Clamp shock
upside down . Clamp vise on top
mount with shock vertical in vise
(do not clamp on reservoir tube) .
Rear shocks may be tested on the
vehicle by disconnecting the lower
mount . Completely extend to
full rebound then exert an extra
pull . If a "give" is felt, a loose
piston is indicated and the shock
should be replaced . A hissing
noise (orifice swish) is normal ;
however, replace shock absorber
for any of the following:
l . A skip or lag at reversal
near mid-stroke .
2 . A seize (except at either
extreme end of travel) .
3. A noise such as a grunt
or squeal after completing
one full stroke in both dir-
ections.
4. A clicking noise at fast
reversal .
SHOCK ABSORBER- l . Faulty shock absorber .
l . A slight trace of shock fluid is
LEAKS .
NOT cause for replacement as
the seal permits some seepage
for lubrication of the piston rod .
The shock contains a fluid reverse
to compensate for seepage . A
shock that is truly leaking is easily
detected as there will be evidence
of shock fluid around the seal cover
and on down the reservoir tube;
any leaking shock should be re-
placed.
