* Rear suspension bushings: These connect various parts of the rear suspension (like control arms, trailing arms, or sway bar) to the chassis. These *do* wear out and need replacing.
* Other rear suspension components: The rear suspension may have other parts that wear out, such as ball joints (if applicable), shocks/struts, or springs.
To determine what needs repair, you'll need to:
1. Identify the specific problem: What symptoms are you experiencing that led you to believe the rear axle bushings need replacing? (Noise, handling issues, etc.)
2. Consult a repair manual: A repair manual specific to your 2007 Chevy Aveo will show you the rear suspension components and how to diagnose and repair them.
3. Take it to a mechanic: If you're not comfortable working on your car yourself, a qualified mechanic can diagnose the problem accurately and perform the necessary repairs.
In short: There's no such thing as replacing rear axle bushings on a FWD Chevy Aveo. You need to pinpoint the actual problem causing the issue.
