Subframe and Mounting Systems
WARNING: This page is about a different car, the 2009 Mercury Milan, 2009 Lincoln MKZ, and 2009 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
Front Subframe - The front subframe is bolted to the body and is used to:
- aid in structural support.
- provide mounting surfaces for the front suspension control arms.
- provide a mounting point for the engine isolators.
- provide the mounting surface for the steering gear.
- provide the mounting surface for the sway bar.
Rear Subframe - The rear subframe is bolted to the body and is used to:
- aid in structural support.
- provide the mounting surface for the rear suspension upper control arms, rear suspension lower control arms and (if equipped) a mounting location for the rear differential.
Underbody misalignment can affect front and rear wheel alignment, the operation of the suspension parts and drivetrain operation. Window glass cracks, door and window opening concerns and air or water leaks at the doors are often caused by incorrectly tightened bolts and body misalignment. For information on underbody dimensions, refer to BODY REPAIRS article.
