Service Bulletin/Repair Instructions
INSTRUCTIONS TO INSPECT LEVELING CHAINS AND REMOVE ANY WITH INDICATED MANUFACTURER MARKING AND DATE CODE FOR REPLACEMENT

Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
