Front Steering Knuckle: Description and Operation

The front knuckle is a machined aluminum casting. Do not use a hammer to loosen suspension components from the knuckle. Suspension components attached to the knuckle (i.e. front lower control arm ball stud, ABS sensor bracket, arid strut damper) are made of steel and have special coatings to prevent corrosion.
