15:55 Direction of grease Zerk installation
23:45 Preparing to install the universal joint into the slip yoke
24:14 Three tools needed to install a universal joint bearing cap
25:30 Why using a Vise can cause universal joint damage
27:15 Setup the Yoke and universal joint cross for installation

34:45 installing one copper-colored snap ring
35:55 preparing to install the opposide snap ring
37:45 Copper-colored snap ring not fitting
38:58 Adjusting the cross and bearing cup positions to remove endplay
42:00 Why selectable thickness snap rings are needed
44:00 Installing thinner snap rings
47:47 Removed universal joint to inspect again
48:28 Measuring cross-width variation
50:42 Cleaning the yoke again
52:00 Universal joint reinstalled in the yoke
54:35 installing the universal joint into the aluminum driveshaft

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 many different thicknesses of snap rings came in the GM universal joint kit?
2. Why would someone want to perform a yoke line bore inspection?
3. In which direction should a grease Zerk face when installing a universal joint?
4. What three tools are needed to install a universal joint bearing cap
5. In which direction should a bearing cap always face when handling and installing it?
6. Look at timeframe 30:55. Describe axial endplay in your own words
7. Why did the second copper snap ring not fit in the slip yoke snap ring groove?
8. What thickness of snap rings finally fit in the grooves of the slip yoke?
9. How much cross width variation did the universal joint in this video have?
10. What color of snap rings were installed on the driveshaft side of the universal joint?
