Uni-Body, Subframe and Mounting System: Other Ford Edge I

Subframe and Mounting Systems

Front Subframe - The front subframe is bolted to the body and is used to

1. aid in structural support.
2. provide mounting surfaces for the front suspension control arms.
3. provide the mounting surface for the steering gear.
4. provide the mounting surface for the sway bar.

Rear Subframe - The rear subframe is bolted to the body and is used to

1. aid in structural support.
2. provide mounting surfaces for the rear suspension control arms.
3. provide a mounting point for the rear differential, if equipped.
4. provide a mounting surface for the sway bar.

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 body misalignment and checking, refer to BODY REPAIRS article. Before any welding is carried out on the vehicle, refer to BODY REPAIRS article.
