Repairing a knocking suspension can cost between $150 and $1,000, depending on the underlying issue and the vehicle type. Common causes include worn-out shock absorbers, damaged struts, or loose components. To determine the exact cost, a professional inspection is essential.
What Causes a Knocking Suspension?
Understanding the root causes of a knocking suspension can help you make informed decisions about repairs and maintenance. Here are some common reasons:
- Worn Shock Absorbers: These components absorb the impact of the road. When they wear out, they can cause a knocking sound.
- Damaged Struts: Struts are integral to your vehicle’s suspension system. Damage can result in knocking noises, especially over bumps.
- Loose or Damaged Components: Parts like control arms, ball joints, or sway bars can become loose or damaged, leading to noise.
- Worn Bushings: Bushings cushion suspension components. When they wear out, knocking noises can occur.
How Much Does It Cost to Fix a Knocking Suspension?
The cost of repairing a knocking suspension varies widely based on several factors:
| Component | Average Cost Range | Description |
|---|---|---|
| Shock Absorbers | $200 – $400 | Includes parts and labor for replacement. |
| Struts | $450 – $900 | More complex, includes alignment. |
| Control Arms | $150 – $400 | Varies based on the vehicle make. |
