Control arm bushings are small yet vital components for your car’s suspension system. If your vehicle feels unstable or produces a clunking noise during turns, worn bushings may be the culprit. This guide will answer common questions about replacing control arm bushings, installing them correctly, and their lifespan, along with helpful insights to keep your vehicle in top shape.
A control arm bush is a rubber or polyurethane component mounted between a vehicle’s control arm and frame. It acts as a cushion, reducing vibrations and allowing the suspension to move smoothly.
Over time, these bushings endure significant stress. Frequent exposure to extreme temperatures, road salt, and general wear can cause them to crack or deteriorate. For drivers, this means reduced handling and stability—a problem that must be addressed promptly to ensure safety on the road.
Replacing a control arm bush may sound technical, but with patience and the right tools, the process can be manageable. Follow these steps for effective replacement.
Tools and Supplies Needed
Jack and jack stands
Wrench and socket set
Hammer
Torque wrench
Replacement bushings (ensure they match your vehicle model)
Press tool (if necessary)
Use a reliable jack to lift your car and secure it on jack stands. Always work on a flat, solid surface.
Unscrew the nuts and take out the wheel to gain access to the control arm.
Loosen and remove bolts connecting the control arm to the car frame and suspension assembly. This might require additional leverage if components are tightly secured.
Check the old bushing for signs of cracking, tearing, or outright damage to assess its condition before removal.
Use a press tool or hammer to knock out the old bushing carefully. Avoid damaging the control arm itself during removal.
Once the old bushing is out, installing the new arm control bushing requires careful alignment and precision.
Lubricate the outer edges of the new bushing with silicone grease for smoother installation. Avoid using petroleum-based products as they can degrade rubber bushings.
Position the new bushing at the control arm’s mounting point. Be sure it matches the orientation of the old bushing.
Use a press tool to insert the bushing securely into the control arm. If you don’t have a press, visit a professional mechanic to avoid improper fitting.
Re-bolt the control arm to the car’s frame and suspension system, ensuring all nuts and bolts are torqued to the manufacturer’s specifications.
Take the car for a short drive and listen for any unusual noises. If everything feels solid and stable, your installation is likely successful.
Pro Tip: Whether replacing a front lower control arm bushing or rear bushing, always replace bushings in pairs (e.g., left and right sides). This ensures consistent handling and even wear.
On average, control arm bushings last between 80,000 and 100,000 miles. However, this figure can vary depending on driving conditions, vehicle weight, and bushing material.
Signs Your Bushings Need Replacement
Clunking noise when driving over bumps
Uneven or excessive tire wear
Poor handling or steering alignment
Vibrations in the steering wheel
Extreme climates and rough roads can accelerate wear. Regular inspections during oil changes or tire rotations can help catch failing bushings early.
A: Driving with a damaged bushing is not recommended. It compromises your vehicle's handling and can wear out other suspension components, leading to costly repairs.
A: The cost varies depending on your vehicle and labor rates. On average, expect to pay $200-$500 per side for parts and labor. DIY replacement can save money, but requires the necessary tools and expertise.
A: Polyurethane bushings are more durable and offer better performance under stress. However, they can transmit more noise and vibrations compared to rubber bushings.
