Rear Subframe: Description and Operation
REAR SUBFRAMEThe rear subframe is bolted to the body and is used to:
- aid in structural support.
- provide mounting surfaces for the rear suspension control arms.
- provide a mounting point for the rear differential, if equipped.
- 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.
