Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
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. 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 UNDERBODY DIMENSIONS .
