Chatter on Corners

Chatter on corners is a condition where the whole rear end vibrates. Chatter noise on Traction-Lok axles can usually be traced to erratic movement between adjacent clutch plates. It can be corrected by replacing the lubricant with High Performance Synthetic 75W140 Rear Axle Lubricant or equivalent, meeting Ford Specification WSL-M2C192-A and Additive Friction Modifier or equivalent, meeting Ford Specification EST-M2C118-A.
