🔌 Function

⚠️ Common Signs of Failure

• Nut backing off, leaving the joint slack
• Thread damaged, crossed or seized to the stud
• Corners rounded so a spanner slips
• Rust staining running from the joint

🛠️ Service Notes

• Toothed washer 984991 shares the same two kits and the same 27 applications, so the two are fitted together. Order the pair, or take kit 3808886 or 3808887 which contains both
• If the joint has been working loose, renew the washer as well as the nut, because a flattened washer will not hold the new nut
