The control arm is a key part of your car’s suspension system. It connects the wheels to the car frame and helps keep your ride stable, smooth, and safe. Over time, control arms wear out due to rough roads, heat, and daily driving in the UAE. When this happens, handling becomes poor, and safety is reduced.
This guide explains how to replace an upper or lower control arm, common warning signs, tools needed, and when expert help from Royal Prince Autocare makes more sense.
What Is a Control Arm?
A control arm links the suspension to the vehicle chassis. It allows the wheel to move up and down while staying aligned. Most cars have:
- Upper control arms
- Lower control arms
Each arm includes bushings and sometimes a ball joint. When any of these fail, the whole arm often needs replacement.
Signs Your Control Arm Needs Replacement
Watch for these apparent symptoms:
- Clunking noise over bumps
- Steering wheel vibration
- Uneven or fast tyre wear
- Vehicle pulling to one side
- Loose or unstable steering
A proper Car Inspection helps confirm whether the issue is with the control arm or another suspension part.
Why Control Arms Fail Faster in the UAE
Driving conditions in Dubai and across the UAE put extra stress on suspension parts:
- High temperatures dry out rubber bushings
- Speed bumps and rough roads damage joints
- Dust and sand wear moving parts
That is why regular Suspension Repair checks are essential for long-term safety.
Tools Needed to Replace a Control Arm
If you plan to replace it yourself, you will need:
- Jack and Jack stand
- Socket and wrench set
- Breaker bar
- Ball joint separator
- Torque wrench
- Penetrating oil
This job requires strength, precision, and correct torque values.
Step-by-Step: How to Replace a Control Arm
Step 1: Prepare the Vehicle
Park on level ground. Engage the parking brake. Loosen the wheel nuts slightly before lifting the car.
Step 2: Lift and Secure
Raise the vehicle using a jack and secure it with jack stands. Remove the wheel.
Step 3: Locate the Control Arm
Find the upper or lower control arm attached to the wheel hub and frame.
Step 4: Disconnect the Ball Joint
Use a ball joint separator to release it carefully. Avoid damaging nearby parts like brake lines.
Step 5: Remove Mounting Bolts
Spray penetrating oil if the bolts are tight. Remove bolts connecting the control arm to the chassis.
Step 6: Install the New Control Arm
Position the new control arm correctly. Hand-tighten bolts first, then torque to manufacturer specs.
Step 7: Reconnect Ball Joint
Secure the ball joint and ensure it is fully seated.
Step 8: Reinstall Wheel and Lower Vehicle
Put the wheel back on, lower the car, and torque the lug nuts.
Wheel Alignment Is Mandatory After Replacement
Replacing a control arm changes suspension geometry. Without Wheel Alignment, you may face:
- Poor handling
- Steering pull
- Rapid tyre wear
Alignment should always be done immediately after the repair.
Upper vs Lower Control Arm Replacement
Upper control arms mainly affect steering angles.
Lower control arms carry more load and impact ride comfort.
Lower arms often fail sooner and cost more due to added stress.
Cost of Control Arm Replacement in Dubai
Costs vary depending on:

Luxury and SUV models usually cost more due to complex suspension designs.
DIY vs Professional Replacement
DIY may seem cheaper, but mistakes can lead to:
- Unsafe handling
