Weber State University (WSU) - Automotive Technology Department - Transmission Lab. The on-car measurement procedure of wheel axle shaft runout. Axle shaft runout and can cause first-order tire speed-related vibrations.

Timeline:
0:00 Introduction
0:48 Axle shaft center hub radial runout measurement setup
4:10 Axle shaft center hub radial runout measurement = 0.002" (0.051 mm) within the 0.003" (0.076 mm) specification
5:32 Axle shaft lateral runout measurement setup
7:05 Axle shaft lateral radial runout measurement = 0.003" (0.076 mm) within the 0.003" (0.076 mm) specification
8:10 Axle shaft lateral with brake rotor runout measurement setup
9:35 Brake rotor hub area surface rust can affect runout. Use alignment marks
10:55 Axle shaft lateral with brake rotor runout measurement = 0.065" (1.65 mm) not within the 0.003" (0.076 mm) specification
13:25 Why did the lateral runout increase?
