Types of nissan lower control arm

A Nissan lower control arm is a crucial part of a vehicle's suspension system. It connects the vehicle's frame to the wheel hub assembly. This control arm enables the wheels to move up and down without affecting the car's body. As a result, control arms help maintain the vehicle's stability and balance. However, lower control arms are more common in front-wheel-drive cars. Below are the different types of Nissan lower control arms.

• Multi-Bar Independent Suspension Control Arms

  Multi-bar independent suspension control arms have more than one control arm. This suspension system is popular in luxury cars and high-end sports cars. The more control arms give the wheels more independent movement. As a result, the wheel maintains better contact with the road. The multi-bar independent suspension control arm improves cornering performance and enhances the overall handling of the car.

• MacPherson Strut Suspension Control Arms

  MacPherson strut suspension control arms are popular in modern cars. This control arm combines the shock absorber and the steering axis in one unit. The MacPherson strut suspension system reduces the number of control arms to one. As a result, this suspension system requires less space and is more cost-effective. The MacPherson strut suspension control arm provides good handling and stability. This control arm is ideal for small cars and everyday use.

• Double Wishbone Control Arms

  Double wishbone control arms are a common type of front lower control arm. This control arm has a two control arm setup, which resembles the shape of the letter W. The double wishbone control arms offer more control over the wheel's movement. The control arms keep the wheel perpendicular to the road. As a result, the double wishbone control arms improve the car's stability and handling. This control arm is ideal for sports cars and vehicles that need high performance.

• Stamped Steel Control Arms

  Stamped steel control arms are often used in older cars and trucks. These control arms are made from steel sheets. The stamped steel control arms are strong and affordable. However, these control arms are heavier than other control arms. Stamped steel control arms are mostly found in vehicles with simple suspension systems.

• Aluminum Control Arms

  Nissan lower control arms are made from aluminum. Aluminum control arms are lightweight and resistant to corrosion. The aluminum control arms help improve the car's fuel efficiency. However, aluminum control arms are more expensive than steel control arms. Aluminum control arms are ideal for modern cars and electric cars.

• Cast Iron Control Arms

  Cast iron control arms are strong and durable. These control arms can withstand a lot of stress and heavy loads. Cast iron control arms are mostly found in heavy-duty vehicles like trucks and buses. However, the cast iron control arms are gradually becoming obsolete.

Specifications and Maintenance of Nissan Lower Control Arm

Specifications of the Nissan LCAs differ based on the make and model of the car. However, some common specifications include:

• Material

  The LCAs are made of different materials. This includes aluminum, steel, and cast iron. Each material has its advantages. For example, steel is very strong and durable, while aluminum is lightweight and resistant to corrosion.

• Size and weight

  The size of the control arms differs depending on the car model. Larger vehicles have bigger LCAs. Additionally, the control arms are designed to be lightweight to improve the vehicle’s performance.

• Mounting points

  As mentioned earlier, the LCAs connect to the vehicle’s frame and the steering knuckle. The mounting points are positioned precisely to ensure the LCAs work efficiently. The mounting points are also reinforced to prevent wear and damage.

• Bushing and Ball Joint

  Like the rest of the suspension components, the Nissan lower control arm needs regular maintenance to function optimally and improve the vehicle's handling. Proper maintenance increases the lifespan of the control arms. Below are some of the maintenance tips.

  Check the ball joint and bushings for any signs of wear or damage. In case of any, replace them immediately. The control arms bushings should be lubricated regularly to prevent cracking due to dryness. Ensure that the LCAs are properly aligned. Improper alignment puts a strain on the control arms and can cause damage. Also, check the LCAs for any signs of rust or corrosion, especially for those made of steel. In case of any, apply anti-corrosion treatment to prevent further damage. Ensure that the nuts and bolts of the control arms are tightened properly. Loose fittings can cause the control arms to wobble, leading to damage.

How to Choose Nissan Lower Control Arm

There are several factors to be considered when buying Nissian LCAs. They include:

• Vehicle Compatibility

  Select the control arms designed for the vehicle's make, model, and year. Using an incompatible control arm can cause poor fitment and premature failure.

• Quality and Reliability

  Prioritize control arms from reputable brands known for their quality and reliability. Reading online reviews can help find trustworthy manufacturers.

• Warranty

  Nissian lower control arms that are backed with a warranty offer assurance of quality. The warranty gives the customer a chance to return or exchange a product that is faulty.

• Budget

  While it is important to consider the cost of lower control arms, avoid overspending or underfunding. Find a control arm that is within the price range and offers quality.

How to DIY and Replace Control Arms

A Nissan control arm replacement can be done at home with the right tools and mechanical knowledge. It is advisable to first read the service manual for the specific Nissan model. The guide provides important information like the location of the control arm, torque specifications, and steps to disassemble and assemble parts.

The basic tools needed for this project include a floor jack and jack stands, wrenches, sockets, pliers, a hammer, a torque wrench, and a breaker bar. The control arm bushings may also need to be pressed in or out using a press tool. Other important parts that may be needed for this project include new lower control arm bolts, bushings, and possibly a ball joint assembly.

• Lift the Vehicle

  Park the car on a flat surface and engage the parking brake. After, disconnect the negative battery cable and use the floor jack to lift the vehicle. Then, place the jack stands under the vehicle to provide stability and safety for the repair work.

• Remove Wheels

  Use a wrench or a tire iron to remove the wheel nuts and take out the wheels.

• Disconnect the Suspension Parts

  Depending on the model, the control arm will be attached to the vehicle body with bolts. Disconnect the control arm and the suspension parts connected to it.

• Remove the Ball Joint (if necessary)

  Some control arms are directly attached to the steering knuckle with a ball joint. If this is the case for the Nissan vehicle, it will be necessary to disconnect the ball joint from the control arm.

• Detach the Control Arm from the Chassis

  Unscrew the bolts that attach the control arm to the vehicle's chassis. This will allow the control arm to be removed easily.

• Remove and Replace Control Arm Bushings (if necessary)

  Some control arms come with bushings fitted into the arm. These bushings are either pressed in or bolted on. Remove the bushings with a press tool or by unscrewing bolts. For bushing fitted with bolts, it is important to verify that the new bushings holes align with the control arm.

• Install the New Control Arm

  Place the new control arm into position and secure it to the chassis with bolts. Reconnect the ball joint to the steering knuckle if necessary. Reconnect the suspension parts and tighten all bolts and nuts to the recommended torque specifications.

• Reassemble the Suspension and Wheels

  Put the wheels back into position and lower the car from the jack stands. Reconnect the negative battery cable and ensure that the wheel nuts are properly tightened.
