Repco offers a comprehensive range of control arms designed to meet the demands of both everyday drivers and automotive professionals. Whether you need a front lower control arm, upper control arm, or rear control arm, Repco’s selection combines durability and precision engineering to help maintain your vehicle’s handling and safety. Backed by trusted brands such as TRW, Kelpro, Nolathane and Vaico, these control arms car parts provide reliable performance and are suitable for a wide variety of makes and models.
Modern control arms car suspension systems are engineered to manage constant load, road shock, and steering forces. While the metal arm itself is typically robust, wear commonly occurs in the integrated ball joints and control arm bushes. Over time, these parts can deteriorate due to heat, contamination, rough roads, towing loads, and general kilometre accumulation. Replacing worn components restores suspension geometry and improves handling consistency.
How much does it cost to replace a control arm?
The cost of a control arm replacement depends on vehicle type, suspension complexity, and whether aftermarket or original equipment parts are selected. A lower control arm commonly ranges from $200 to $600 per arm, with labour costs added separately. Vehicles with multi link suspension or aluminium arms may increase overall pricing.
When reviewing costs, it is important to confirm whether the replacement part includes pre fitted ball joints and control arm bushes. Many modern assemblies are supplied as complete units, simplifying installation and ensuring component compatibility. If bushes are not included, they may need to be pressed in separately, adding labour time.
How long does it take to change a control arm?
Replacing a front lower control arm or rear control arm generally takes between one and three hours. Time varies depending on accessibility, corrosion levels, and whether mounting bolts or suspension components require additional attention. Workshops with hoists and specialised tools may complete the task more efficiently than ground level installations.
After installation, a wheel alignment is required. Suspension geometry changes even slightly during a lower control arm replacement, and correct alignment ensures stable handling and even tyre wear.
What other things should I check when changing a control arm?
When replacing control arms car suspension components, inspecting related parts is a practical step. Ball joints, tie rod ends, sway bar links, and wheel bearings should be checked for play or wear. If the vehicle has high kilometres, examining shock absorbers and suspension springs is also advisable.
Control arms bushes in adjacent positions should be assessed for cracking, splitting, or excessive movement. Addressing these items during the same service can reduce repeat labour and help maintain consistent suspension performance.
What is the average life span of a control arm?
The metal structure of upper control arms and front lower control arms is designed for long term durability. However, the wear components attached to them, particularly bushes and ball joints, generally last between 150,000 and 200,000 kilometres under normal driving conditions.
Frequent travel on rough roads, off road driving, heavy towing, and exposure to water or road contaminants can shorten service life. Regular inspection during routine servicing helps identify cracking rubber bushes, looseness, or knocking noises before more significant suspension issues develop.
Do I need specialist tools to change a control arm?
Replacing a control arm car suspension component typically requires a ball joint separator, a torque wrench, and standard socket and spanner sets. Some vehicles may require a spring compressor if the suspension design places load on the arm during removal.
Correct torque settings are essential to ensure mounting bolts are secured properly without over tightening. Access to manufacturer specifications and safe lifting equipment supports accurate installation. While experienced DIY enthusiasts may complete the task, professional installation can provide added confidence in safety critical suspension systems.
Complete the Suspension Repair Properly with the right parts from Repco
When fitting a new lower control arm or upper control arm, it is practical to inspect surrounding suspension and steering components at the same time. Repco’s Steering and Suspension category includes tie rod ends, sway bar links, and suspension bushes that may also require attention. After installing control arms, a professional wheel alignment is recommended to protect tyre life and maintain predictable handling. It is also wise to check braking components while the vehicle is raised, and the Brakes category provides pads, rotors, and hydraulic parts to help complete the job thoroughly. Taking a methodical approach ensures your new control arm performs as intended and supports long term vehicle reliability.
