Worn out U-joints can make a variety of noises. The most common indicator is a light metallic click when you first accelerate from a standstill. Light acceleration and deceleration can often cause the U-joint to click continuously (as a test). Checking for a faulty U-joint should be left for the experienced do-it-yourselfer or your mechanic. Have U-joints inspected at least annually, as complete U-joint failure can be dangerous and very expensive.

U-joint replacement on most Volvos is not easy. For best results have them replaced by an experienced Volvo specialist or drive-line shop.

Since it is difficult to measure the width of a U-joint when it is installed, we have provided the width of the U-joint yoke, which can easily be measured with a set of calipers.

If the yoke width is 2-3/4" use the 2-5/8" U-joint #101563

If the yoke width is 3-1/4" use the 3" U-joint #101564

If the yoke width is 3-1/2" use the 3-3/16" U-joint #104512

NOTE: Whenever removing the driveshafts from your Volvo, be sure to index the two shafts together so you can make sure they are re-assembled in the proper orientation as yoke alignment and balance is critical. An error here will result in a mild to severe vibration at speed.
