September 24, 2010

Vehicle Information

Condition

Front Suspension, Knocking Noise

Knocking noise from vehicle front. Typically occurs only one time after each direction change (forward or backward, left or right).

Technical Background

The sub frame shifts slightly relative to the body due to wax residue in-between components. Maximum acceleration and braking in vehicles that are
driven hard are contributors to the occurrence.

Production Solution

Final production countermeasure pending.
