Rear Subframe: Description and Operation
FRAME ASSEMBLYRear 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.
