Description
The four u-bolts nuts on either side of the rear axle were under-torqued.

Consequence

Corrective Action

DEFECT #2 - TIRES: BEAD

Description
These tires have bead damage which occured during tire mounting.

Consequence
This damage to the tire reinforcing structure in the bead toe area causes a bulge in the sidewall after the tire is inflated.  This condition will result in a slow air loss causing the tire to go flat.  However, it is possible for the damage to result in a rapid air loss causing injuries to anyone if they were handling the tire when this occurred.

Corrective Action
Dealers will demount each tire and inspect for bead damage.  If bead damage is found, the tire will be replaced.
