What are Rear Suspension Springs and How Do They Work?
The rear suspension springs are vital components of your vehicle’s suspension system. They support the vehicle’s weight, absorb shocks from road irregularities, and help maintain proper ride height and handling stability.
Springs work alongside shock absorbers or struts to smooth out the ride. While shocks control motion, springs store and release energy to absorb impacts, keeping your tires in contact with the road and your vehicle balanced.
Why Rear Suspension Springs Matter
Worn or damaged rear springs can:
- Cause sagging or uneven ride height
- Reduce handling stability
- Increase tire wear
- Lead to harsh, uncomfortable rides
Replacing faulty springs restores proper suspension geometry, smooth ride quality, and safe handling.
Important to Know:
- Rear springs are typically coil or leaf type, depending on vehicle design.
- They are built to last 80,000–100,000 miles, but heavy loads, rough roads, or accidents can shorten their lifespan.
- Always inspect other suspension components when replacing springs, as shocks/struts and bushings may also need service.
How Rear Suspension Spring Replacement is Done:
- Inspect rear springs for sagging, cracks, or rust.
- Safely lift and support the vehicle.
- Remove the rear wheels and any components blocking spring removal.
- Carefully remove the worn spring(s).
- Install new OEM-quality rear springs, ensuring proper alignment.
- Reassemble suspension components and wheels.
- Lower the vehicle and test drive for proper ride height and stability.
When to Replace Rear Suspension Springs:
- If the vehicle sags or tilts to one side
- After a severe impact or accident
- When springs show visible cracks, rust, or deformation
- Alongside shocks/struts replacement for balanced suspension performance
Signs You May Need Rear Suspension Spring Replacement:
- Vehicle leaning to one side or sagging
- Rough or bouncy ride
- Uneven tire wear
- Suspension noise when going over bumps
- Rear end feels unstable during turns or braking
