Drive shaft noises are usually caused by worn U- joints, slip joint wear, or a faulty center support bearing. Drive shaft noises and possible causes are as follows: · Grinding and squeaking from the drive shaft is frequently caused by worn universal joints. The joints become dry, causing the rollers to wear. The unlubricated, damaged rollers then produce a grinding or squeaking sound, as they operate on the scored cap and cross surfaces. · A clunking sound, when going from acceleration to deceleration or deceleration to acceleration, may be caused by slip yoke problems. The splines may be worn. The yoke transmission extension housing bushing may also be worn. This will let the yoke move up and down with changes in drive line torque. An excessively worn U-joint or differential problem can also cause a similar noise. · A whining sound from the drive shaft is sometimes caused by a dry, worn center support bearing. Since this bearing makes complete revolutions. it will make a different sound than a bad universal joint. A high pitched. More constant, whine will usually come from a faulty center support bearing. Any other abnormal sound should be traced using your knowledge of mechanics. A stethoscope and the vehicles service manual troubleshooting chart.
