How long does a drive shaft last?

about 75,000 milesIf you allow the driveshaft to die completely, then it will reach the point where the wheels no longer receive any power.

Grinding and squeaking sounds from the drive shaft are frequently caused by worn universal joints. … Clunking sound, when going from acceleration to deceleration or deceleration to acceleration, may be caused by slip yoke problems. The splines may be worn.

What is driveline phasing?

What is Phasing? o Phasing is a term used to describe the alignment of the yokes with each other at both ends of the driveshaft. Phase angle is the relative rotational position of each yoke on a driveshaft or coupling shaft. When the yoke ears are in line with each other, this is referred to as “in phase”.
