A bushing is a lined hole or sleeve that reduces friction and acts as a cushion between two parts. It is used in various mechanical components, such as control arms, transmission mounts, and axle housings. The bushing for VW is available in different types, as discussed below.
Polyurethane Bushings
This type of bushing is made of polyurethane material. It is a synthetic version of rubber that is very durable. The polyurethane bushings improve the stability and handling of the vehicle. Because they are firmer, they reduce the body roll, making the car feel more balanced. This bushing for VW is popular in sports and performance vehicles. They also reduce the car's tendency to lean on one side during acceleration. The main downside of polyurethane bushings is that they increase the noise level of the vehicle. They also put more strain on other suspension components.
Rubber Bushings
A rubber bushing is one of the most common types of bushings found in vehicles. It is used in various suspension components, such as control arms, shock absorbers, and leaf spring mounts. The rubber bushing cushions the vehicle parts to reduce noise and vibration. It also allows for a small degree of movement without damaging the components. Rubber bushings provide a smooth and quiet ride. However, they may wear out quickly and need regular replacement.
Metallic Bushings
This bushing for VW is made from different metals, including bronze, copper, and aluminum. Metallic bushings are very durable and have a long lifespan. They are mostly used in heavy-duty applications. The bushing can handle high loads and reduce wear and tear on rotating shafts.
Graphite Bushings
Graphite bushings are self-lubricating bushings. They do not require a lubricant to function properly. They have good chemical resistance and can withstand high temperatures. Graphite bushings are mostly used in high-temperature and corrosive environments. For instance, they are used in the railway and mining industries.
Brass Bushings
This bushing for VW is made of brass. It is commonly used in electrical applications such as wiring harnesses and connectors. Brass bushings ensure good electrical conductivity in various vehicle components.
Role in Vehicle Suspension
The front and rear axles of a vehicle bear the weight of the car and its cargo. Bushings help to provide a firm base for the mounting of control arms and axles. Bushings help the control arms to be positioned correctly so that the front wheels can steer properly. Bushings also help the control arms and axles to move without binding. This allows the suspension to absorb bumps without breaking down.
Material Composition
VW bushings are made of three main materials. One of them is rubber. Rubber bushings for VW parts are popular because they are quiet. They help to keep the noise from reaching the vehicle occupants. Rubber bushings also provide good traction. However, rubber bushings wear out fast. Drivers who stress their vehicles too much should avoid rubber bushings. The second material is polyurethane. Polyurethane bushings are long-lasting. They help to improve the handling of the vehicle. Polyurethane bushings are suitable for vehicles that go off the road or that drive on the highway. The third material is nylon. Nylon bushings give a vehicle a firm feel. They are useful for racing cars.
Types of Bushings
The VW brand makes different models of vehicles. The type of bushing to use depends on the model of the car. For instance, the VW Golf uses the tie rod end bushing, control arm bushing, sway bar bushing, and shock absorber bushing. The tie rod bushing helps to connect the steering wheel to the front wheels. It helps the driver to steer the car. The control arm bushing links the control arm to the chassis of the car. It allows the control arm to move up and down. It also helps the control arm to stay in position. The sway bar bushing links the sway bar to the vehicle's frame. It helps the sway bar to twist. The shock absorber bushing links the shock absorber to the vehicle. It prevents the shock absorber from making noise.
Inspection
It is important to inspect the bushing before using it. Check for signs of wear and tear. Look for cracks, splits, and gaps. Also, check for damage like distortion and damage. Make sure that the bushing is still the right size. Measuring the bushing will tell if it has shrunk. Compare the size of the bushing with the hole it is supposed to fill. The fit should be snug.
Lubrication
Bushings need lubrication to function well. Lubrication helps to reduce friction. It also helps to prevent binding. Use the right type of grease to lubricate the bushing. The grease should be suitable for the material of the bushing. For instance, nylon bushings use lithium-based grease. Rubber bushings use silicone-based grease. Polyurethane bushings use PTFE grease. Use a clean cloth to wipe off any excess grease.
Replacement
Over time, the bushing will wear out. When this happens, it is important to replace the worn-out bushing. Fitting a new bushing will help to restore the original condition of the suspension. This will help to make the vehicle ride smoothly. Changing the bushing early will prevent damage to the control arm, tie rod, or shock absorber.
When buying car suspension bushings, here are some important things to consider:
Material
Bushings are made of different materials, and each material has its own benefits. Rubber bushings are the most common and affordable. They are good at noise and vibration damping, but they wear out easily. Customers can also choose polyurethane bushings. They are more durable and improve handling, but they generate more noise. Selecting the bushing material depends on the customer's budget and needs.
Application
Consider the part of the suspension system where the bushing will be used and the specific function it serves. Different suspension components may require bushings with varying sizes and characteristics. For example, control arms, sway bars, and shock absorbers all have different bushing requirements.
Size and fitment
Buyers should ensure they get the right bushings to fit their suspension components. This will prevent premature wear and damage. It's advisable to measure the dimensions of the old bushings or refer to the manufacturer's specifications to make sure of the size.
Quality and brand reputation
To get suspension bushings that will last long, it's advisable to buy them from reputable manufacturers. Quality bushings are made from durable materials and have precise measurements. Buyers can read online reviews or ask fellow car owners for recommendations.
OEM vs. aftermarket bushings
Original equipment manufacturer (OEM) bushings are identical to the ones that come with the car. They offer the best fit and reliability, but they may be more expensive. Aftermarket bushings are more affordable and come in different sizes. Whichever the case, buyers should ensure that the bushings are compatible with their vehicles.
Warranty
Buyers should look for bushing suppliers that offer a good warranty period. A warranty is an assurance that the product is of good quality. In case of any defects, the supplier should be able to replace or refund the bushings.
Professional advice
If buyers are not sure about the type of bushings they need, they can consult a professional mechanic. The mechanic can help select the right bushings suitable for the specific suspension needs. The mechanic can also assist with bushing installation.
Here is how to replace the bushing kit for VW in a DIY project:
Q1: How can one tell if the bushing is worn out?
A1: When the bushing is worn out, it causes a lot of disturbances when driving the car. The vehicle might make squeaking noises, particularly when making turns. There might also be a loose feeling in the steering wheel, and the tires might start to wear out unevenly. All these are signs that the bushing might be worn out.
Q2: What is the lifespan of a bushing for VW?
A2: A bushing for VW can last anywhere from 30,000 to 60,000 miles, depending on various factors such as driving conditions, the type of bushing, and the material it is made from.
Q3: Can one upgrade to a stronger bushing?
A3: Yes, it is possible to upgrade to a stronger bushing. A polyurethane bushing for VW is a good option if one is looking to upgrade. These bushings offer better performance and durability compared to the stock rubber bushings.
Q4: What is the difference between an OEM and an aftermarket bushing?
A4: An OEM bushing is manufactured by Volkswagen or its approved partners. It is an exact match to the original bushing that came with the vehicle. An aftermarket bushing is made by a third-party company.
