L PROPELLER SHAFT 2. Remove the propeller shaft from the extension housing, and immediately install the SST to prevent oil leakage. Inspection Propeller shaft Caution Cleaning sealed bearings with cleaning fluids or a steam cleaner can wash the grease out of the bearing. 1. Clean the propeller shaft (except for the universal joint) with a steam cleaner or solvent. 2. Measure the propeller shaft runout with a dial indicator. Replace the propeller shaft if runout is excessive. Maximum runout: 0.4mm (0.016 in} 3. Move the universal joints in the directions shown, and check for universal joint looseness. If there is looseness, replace the propeller shaft. ii 4. Check operation of the universal joint. If the universal joint has excessive resistance, replace the propeller shaft. Installation Note Propeller shaft 1. Align the marks, and install the propeller shaft. Tightening torque: 50-58 N.m (5.0-6.0 kgf.m, 37-43 ft4bf) 2. Verify that there is no abnormal noise or vibration when driving the vehicle. If noise or vibration comes from the propeller shaft, replace the propeller shaft. Gartner Banana
