### U-Joints

#### REMOVAL AND INSTALLATION

##### 240SX and 300ZX

The driveshaft must be removed from the vehicle to inspect the U-joints correctly. Mount the driveshaft in a bench-mounted vise and mount a dial indicator so that it reads forward/rearward motion (axial end-play) of the U-joint. Manually push and pull the U-joint frontward and rearward while reading the dial indicator. The axial end-play should be zero. Next, mount the dial indicator so that it will register any side-to-side movement of the U-joint. There should also be no side-to-side movement. If any front/rear or side-to-side movement is exhibited by the U-joint, the entire driveshaft must be replaced as an assembly. The U-joints are not individually serviceable.
