Driveline clunk (Front Wheel Drive (FWD) vehicles) -- occurs during acceleration or from cruise to coast/deceleration Damaged or worn Constant Velocity (CV) joints INSPECT the inner Constant Velocity (CV) joint and boot. INSTALL a new halfshaft as necessary. REFER to: Front Halfshaft RH . REFER to: Front Halfshaft LH .
Loose hub nut CHECK the torque on the hub nut. REPLACE the hub nut if the torque is not at specification. REFER to: Front Halfshaft RH . REFER to: Front Halfshaft LH .
Driveline clunk -- occurs as the vehicle starts to move forward following a stop Loose hub nut CHECK the torque on the hub nut. REPLACE the hub nut if the torque is not at specification. REFER to: Front Halfshaft RH . REFER to: Front Halfshaft LH .
