Town Car V8-4.6L VIN W (1997)
Differential Clutch: Testing and Inspection
Chatter on Corners
Chatter on corners is a condition where the whole rear end vibrates when the vehicle is turning. The vibration is plainly felt and heard. In conventional
axles, extra differential thrust washers cause a condition of partial lockup that creates this chatter.
Chatter noise on Traction-Lok axles can usually be traced to erratic movement between adjacent clutch plates and can be corrected with a lubricant
change that includes Additive Friction Modifier C8AZ-19B546-A or equivalent meeting Ford Specification EST-M2C118-A.
