INFORMATION
For all repair procedures which require removal of the rear coil springs, the spring seats must be properly cleaned prior to reinstalling the springs.
Dirt, pebbles, and debris left on the spring pads can become trapped between the spring pads and the lower coil of the springs. Debris can damage
the protective coating of the springs. If the protective coating of the spring is damaged, then rust may form on the spring. Over time, rust formation
on the spring, combined with vehicle operating conditions, may cause the spring to break.
