Narrative:
On jul/xa/99, I witnessed 2 tire changes and the torque, along with side play check. I failed to check to ensure that the inner spacer was in place prior to the wheel being placed on the axle. A rotation check was made while torquing to 500 plus pound initial and 150 pounds final torque. No side play was noted. One thread on the axle was noted.
