Piston rod nut
1. Secure the mounting block in a vise.
Caution
l Use protective plates in the jaws of the vise.
2. Loosen the piston rod nut a few turns. Do not remove it.
Caution
l Do not remove the nut.
3. Compress the coil spring with the SST.

5. Remove the coil spring.
Inspection
Check for the following and replace the shock absorber if
necessary.
Secure a handle to the piston rod, and compress and expand
the shock piston at least three times. Verify that the operation-
al force does not change and that there is no unusual noise.
