Factors to Consider when Buying a New Ford Control Arm
Also known as the ‘A' arm or wishbone, the control arm is a component of your Ford vehicle suspension system. Like all the other vehicle components, your Ford control arm must be replaced over time to maintain their productivity. Here are some aspects to take note of to help you choose a control arm wisely.
Designs of Control Arms
There are three main kinds of control arms that are characterized by their design: press in, bolt in, and unitized.
- Press in:This type is best suited for heavy vehicles and industrial applications. The ball joint is bigger than the control arm opening, making the whole system stays securely in position.
- Bolt in:This type is used in the Macpherson type of suspension system and has a stamped strut-type body.
- Unitized:This type is cost-efficient as it has a built-in ball joint. However, if either the arm or ball joint malfunctions, the whole unit must be replaced.
Types of Material Construction
Ford control arm isnormally made of three kinds of materials: drawn-over-mandrel (DOM) mild steel, aluminium, and chromium-molybdenum (chromoly) steel.
- DOM mild steel:This is a process by which the steel tubing is made. The DOM steel is electrically welded and has measurements that are more consistent in relation to the inside and outside measurements of the tube itself.
- Aluminum:The CNC-machined aluminium provides light weight and superior strength. This material construction is not recommended for use in all-out drag application, as the material is not designed for vehicles with greater horsepower. Unlike steel construction, aluminium has a limited fatigue life, which should be considered for load-cycled construction.
- Chromoly steel:Though not as lightweight as the aluminium, the chromoly steel is still lighter than mild steel and has high tensile strength, as well as great psi strength. This steel is easily welded.
Different Bushing Styles
There are different materials for the assembly of your Ford control arm. It can be rubber, polyurethane, all-steel rod end, combination of polyurethane and rod end. Each material and combination has its own pros and cons.
- Rubber:Rubber bushings are highly efficient. Due to its softer material, rubber offers a smoother and more relaxing ride, absorbing vibration or shock from jolts and potholes. In addition, it minimizes road noise. However, rubber degrades faster than polyurethane. It breaks down faster when exposed constantly to extreme temperatures, road salts, and other road conditions.
- Polyurethane:Most vehicles for street use are fitted with control arms that are assembled by using polyurethane bushings, yielding to better resistance to deflection and longer service life. Though it is more durable than rubber, polyurethane bushings release much louder noise.
When sourcing for a suitable control arm, suppliers usually offer control arm kits to help provide easy installation. The kits mostly include all the tools needed, such as the pliers and jack stands. To select the appropriate kit, you should take note of your vehicle make and model, plus your budget. Some of these kits include ball joint or a bushing.
Mevotech Control Arm
What makes the Mevotech control arm outperform its competitors are the metal design of its internal components, which include highly durable metal bearings (lower and upper) surrounding the stud and ball of the ball joint. Precision engineered, this control arm eliminates the strange and annoying sounds or noises coming from the suspension system, making the vehicle work more quietly. The Mevotech control arm is also greasable, allowing the ball joint to be serviced and maintained. With this feature, old grease can be easily flushed out by simply injecting new grease; this maintenance routine helps extend the life span of both the ball joint and the control arm. This control arm also comes with black oxide coating, which provides it with high resistance to corrosion.
Replacement Control Arm
Crafted from high-quality materials to ensure stability and durability, the Replacement control arm is an ideal replacement for a damaged stock. It is an OE comparable unit, so part compatibility will never be an issue. This control arm comes with a ball joint, so both components can be replaced in just one DIY project. Since it is precision engineered, the Replacement control arm can efficiently do the task of holding the vehicle's wheels to the frame while maintaining ideal wheel alignment and reducing road and shock vibration. Vehicle owners can also be sure that this control arm is free from factory, material, and manufacturing defects because it is offered with 1-year, unlimited-mileage warranty.
Autotrust Control Arm
Is there anything better than a 3-year manufacturer's limited warranty? This is the kind of coverage a vehicle owner will enjoy from an Auto Trust Silver control arm. Longer warranty coverage translates to peace of mind because it means that the product is free from any material and manufacturing defect. And if the control arm breaks or gets damaged anytime within the three years from the date of purchase, it will be replaced with a new part. The Auto Trust Silver control arm is an OE-comparable unit, so it can be easily installed in place of the stock without modifications needed.
