Weber State University (WSU) - Automotive Technology Department - Transmission Lab. This is the seventh in a series of videos on universal joints, constant velocity joints, and driveshafts. In this episode, we learn how to properly center universal joints and adjust the axial play. • Timeline: • 0:00 start • 0:10 Introduction • 0:48 Setting up a dial indicator to check the axial endplay • 2:20 Measuring the axial endplay on the universal joint bearing cups in the aluminum driveshaft (0.0035 ) Out of specification of 0.0197 • 3:51 Measuring the axial endplay on the universal joint bearing cups in the steel slip yoke (0.0015 ) Within the specification of 0.0197 • 5:36 Axial endplay on driveshaft side after replacing the copper snap-rings with grey snap rings. (No change in the axial endplay of 0.0035 . • 6:50 Axial endplay on driveshaft side after replacing the grey snap-rings with pink snap rings. (0.0005 ) Within the specification of 0.0197 • 7:20 Summary of specifications • 8:46 What would happen with the aftermarket universal joint installed? • 10:20 The I changed the u-joint and now the vehicle vibrates complaint • 10:41 Universal joint centering is maintained with equal thickness snap rings • 10:50 Universal joint axial play is adjusted with selectable thickness snap rings • 11:22 Differences in factory service information for universal joint service • 11:55 Wrap up • This video series helps partially cover the following NATEF Master Tasks: • 3.D.1. Diagnose constant-velocity (CV) joint noise and vibration concerns; determine necessary action. • 3.D.2. Diagnose universal joint noise and vibration concerns; perform necessary action. • 3.D.4. Inspect, service, and replace shafts, yokes, boots, and universal/CV joints. • 3.D.5. Check shaft balance and phasing; measure shaft runout; measure and adjust driveline angles. • 3.E.4. Measure drive axle flange runout and shaft end play; determine necessary action. • Questions for teachers: • 1. How much axial end play was measured on the slip yoke side with the coated black snap rings? • 2. How much axial end play was measured on the driveshaft side with the copper-colored snap rings? • 3. How much axial end play was measured on the driveshaft side with the grey colored snap rings? • 4. How much axial end play was measured on the driveshaft side with the pink colored snap rings? • 5. How does one center a universal joint in the ears of the driveshaft or yoke? • 6. How does one adjust the axial end play of the universal joint in the ears of the driveshaft or yoke? • 7. How much axial end play would the universal joint in the video have if the aftermarket universal joint on the comparison board was installed rather than the Spicer universal joint? • 8. What can cause the I changed the u-joint and now the vehicle vibrates complaint? • 9. How is driveshaft runout affected by universal joint axial endplay? • Subscribe to the weberauto Youtube channel for more great videos. / weberauto • Visit the following website for information on how to attend our school and obtain an associate's degree or bachelor's degree in Automotive Technology. • http://www.weber.edu/automotive • This video was created and edited by Professor John D.
