Universal Joint Flange

- Make sure the surfaces of the rear axle universal joint flange have not been damaged in removing the driveshaft or in removing the driveshaft centering socket yoke from the rear axle universal joint flange.
- The end of the rear axle universal joint flange that contacts the rear axle drive pinion shaft oil slinger, as well as the flat surface of the pinion nut counterbore, must be smooth. Polish these surfaces if necessary.
- Roughness aggravates backlash noises and causes wear of the rear axle universal joint flange and pinion nut with a loss in pinion bearing preload.
