Honda Odyssey Service Manual: Inspection

Reassemble the damper mounting base, the damper mounting washer (for some models), and the self-locking nut.

Compress the damper assembly by hand, and check for smooth operation through a full stroke, both compression and extension. The damper should extend smoothly and constantly when compression is released. If it does not, the gas is leaking and the damper should be replaced.

Check for oil leaks, abnormal noises, and binding during these tests.
