Control arm bushings are essential components of a vehicle's suspension system, providing cushioning between the control arm and the car's frame. Over time, they can wear out, causing problems with the vehicle's handling, stability, and comfort. If you’re dealing with worn control arm bushings, understanding how to replace them can help restore your vehicle’s performance. In this article, we'll explore how to replace control arm bushings, how long you can drive with bad control arm bushings, and provide a step-by-step guide for installing new ones.
Replacing control arm bushings can be a labor-intensive process, but it is manageable with the right tools and preparation. The control arm is a key part of the suspension system that connects the wheel hub to the chassis of the car. The bushing absorbs shocks and vibrations, ensuring smooth and controlled handling.
Here’s how to replace control arm bushings:
Lift the Vehicle: Start by safely lifting your car using a jack and jack stands. Ensure the vehicle is stable before beginning any work. It’s best to work on a flat surface to avoid accidents.
Remove the Wheel: Once the vehicle is secure, remove the wheel on the side where you’ll be working. This gives you access to the suspension and control arm.
Detach the Control Arm: You’ll need to disconnect the control arm from both the chassis and the wheel hub. This may require removing bolts and other fasteners. Be sure to keep track of all the parts you remove.
Press Out the Old Bushings: After the control arm is removed, the next step is to remove the old bushings. A hydraulic press or a bushing removal tool can help with this. You’ll need to press the old bushings out carefully to avoid damaging the control arm itself.
Install New Bushings: Once the old bushings are out, the new ones can be pressed into place. Make sure the new bushings are aligned correctly, as improper installation can lead to uneven wear or even damage to other suspension components.
Reassemble the Suspension: After the new bushings are installed, reattach the control arm to the car’s chassis and the wheel hub. Ensure all bolts and fasteners are tightened according to the vehicle’s specifications.
Lower the Vehicle: Finally, reattach the wheel and lower the vehicle back to the ground. It’s always a good idea to take the car for a test drive to ensure the repair was successful and the suspension is functioning smoothly.
Replacing changing bushings on lower control arm can take several hours, especially for those with limited mechanical experience. However, it can save a significant amount of money compared to having the work done at a professional shop.
Driving with bad control arm bushings is not advisable for an extended period, as it can lead to several problems. Worn or damaged bushings can cause excessive play in the suspension, which impacts the vehicle’s handling, steering, and alignment. This could make driving dangerous, especially at high speeds or on rough roads.
If your car has bad control arm bushings, you may notice symptoms such as:
● Clunking noises when going over bumps
● Vibrations in the steering wheel
● Uneven tire wear
● Loose or imprecise steering
While it is technically possible to drive with worn bushings, you shouldn’t put it off for too long. The longer you drive with bad control arm bushings, the more damage you risk to other suspension components, which could lead to more costly repairs down the line. Ideally, you should replace bad bushings as soon as symptoms appear.
The installation process for control arm bushings can be broken down into several important steps:
Gather the Necessary Tools: You’ll need a few specialized tools to install new control arm bushings, including a bushing removal tool or hydraulic press, a torque wrench, and various sockets or wrenches to remove fasteners.
Prep the Control Arm: Once you’ve removed the control arm (as described earlier), clean the area around the bushing housings. Remove any debris, rust, or dirt that may have accumulated. This helps ensure the new bushings fit snugly and last as long as possible.
Align the New Bushings: When pressing the new bushings into place, it’s crucial to ensure they are aligned properly. Use the bushing tool or press to carefully insert the new bushings into the control arm housing. Incorrect alignment can lead to premature wear and failure.
Reassemble the Suspension: After the bushings are installed, reassemble the control arm and other suspension components. Make sure all bolts and fasteners are tightened to the manufacturer’s specifications to avoid any issues with loose parts.
Torque the Bolts: Once the control arm is reattached, use a torque wrench to ensure that all the bolts are tightened to the correct torque values. This ensures that the suspension system remains secure and functions properly.
Test the Vehicle: Once everything is reassembled, take the car for a test drive to check the suspension’s performance. Ensure that the steering is responsive and there are no unusual noises or vibrations.
The cost of replacing control arm bushings depends on several factors, including whether you do the job yourself or hire a professional. For a DIY repair, the cost of the bushings themselves ranges from $20 to $100, depending on the vehicle make and model. However, the tools required, such as a bushing press or removal tool, can add to the cost if you don’t already have them.
If you opt to have a mechanic perform the job, labor costs can vary widely. On average, the total cost of replacing control arm bushings at a repair shop can range from $200 to $600, depending on the complexity of the job and the make of the vehicle.
Control arm bushing replacement is an essential part of vehicle maintenance, particularly for older cars or those that have experienced significant wear and tear. If you're experiencing symptoms of bad bushings, it's crucial to address the problem promptly to avoid further damage to your suspension system.
