Axle howling or whine - front or rear axle	Damaged or worn wheel hub bearings	CHECK for abnormal wheel hub bearing play or roughness. REFER to: Front Wheel Bearing .
Driveline clunk - loud clunk when shifting from REVERSE to DRIVE	Damaged or worn Constant Velocity (CV) joints	INSPECT the Constant Velocity (CV) joints for wear or damage. INSTALL a new halfshaft or driveshaft as necessary. REFER to: Front Halfshaft LH or REFER to: Front Halfshaft RH . .
	Loose hub nut	CHECK the torque on the hub nut. REPLACE the hub nut if the torque is not at specification. For front hub nuts. REFER to: Front Halfshaft LH or REFER to: Front Halfshaft RH . .
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 LH or REFER to: Front Halfshaft RH . .
	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 LH or REFER to: Front Halfshaft RH . .
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 LH or REFER to: Front Halfshaft RH . .
Clicking, popping or grinding - occurs while the vehicle is turning	Inadequate or contaminated lubrication in the Constant Velocity (CV) joints	CHECK the Constant Velocity (CV) boots and joints for wear or damage. INSTALL new components as necessary. REFER to: Front Halfshaft LH or REFER to: Front Halfshaft RH . .
	Another component contacting the halfshaft	CHECK the halfshafts and the area around the halfshafts. REPAIR as necessary.
Grunting -- normally associated with a shudder experienced during acceleration from a complete stop	Halfshaft Constant Velocity (CV) joint binding	CHECK the outer Constant Velocity (CV) joint for correct seating into the hub. REPAIR as necessary. REFER to: Front Halfshaft LH or REFER to: Front Halfshaft RH . .
Driveline vibration - occurs at cruising speeds	Incorrectly seated Constant Velocity (CV) joint in the wheel hub	CHECK the outer CV joint for correct seating into the hub. REPAIR as necessary. REFER to: Front Halfshaft LH or REFER to: Front Halfshaft RH . REFER to: Front Wheel Bearing .
