DESCRIPTION
Some vehicles may exhibit a knocking noise from the rear coil spring and/or the vehicle body sits lower in
the rear. These symptoms may be caused by a broken rear coil spring at its lower side.
This is caused by corrosion from dust between the rear coil spring and the spring sheet, resulting in a
broken rear coil spring. To eliminate this concern, the shape of the rear coil spring has been modified.
Customers having this concern should have their vehicle repaired using the following repair procedure.
