Lower Control Arm Bushings: Why are they important?

Subaru’s Common Issue:

Subaru vehicles are known for their reliability and longevity, but even the most well-maintained cars can experience wear and tear over time. One component that often needs replacement in Subaru vehicles is the lower control arm bushings. In this blog, we'll discuss the importance of replacing lower control arm bushings on a Subaru, and what signs to look out for that indicate it's time for a replacement.

What are lower control arm bushings?

First, let's start with what lower control arm bushings are and what they do. The lower control arm is a critical component of a vehicle's suspension system, and the bushings serve as a buffer between the control arm and the frame. They help to absorb shocks and vibrations while also providing a smooth ride. Over time, the rubber in the bushings can wear down, causing them to crack or even completely fall apart.

Why are they important?

So why is it important to replace lower control arm bushings on a Subaru? One of the primary reasons is safety. When the bushings are worn down, they can no longer effectively absorb shocks and vibrations, which can cause the car to feel unstable or wobbly while driving. This can be particularly dangerous at high speeds or when making quick turns. In addition, worn bushings can also affect a vehicle's alignment, causing uneven tire wear and potentially leading to more serious problems down the line.

Replacing lower control arm bushings on a Subaru can also improve the car's handling and overall driving experience. When the bushings are functioning correctly, they help to keep the suspension system properly aligned, which can improve steering response and cornering ability. This can make for a more comfortable and enjoyable ride, as well as help to prevent damage to other components of the vehicle's suspension system.

So how can you tell if it's time to replace the lower control arm bushings on your Subaru? One of the most common signs is a noticeable vibration or shaking while driving, particularly at high speeds. You may also feel a pulling sensation while turning or notice uneven tire wear. Additionally, if you notice that the car's handling feels off or if you hear clunking or banging noises coming from the suspension system, it's a good idea to have the bushings inspected by a qualified mechanic.

Conclusion:

Replacing lower control arm bushings on a Subaru is an important part of maintaining the vehicle's safety and performance. By ensuring that the suspension system is properly aligned and functioning as it should, you can enjoy a smoother, more comfortable ride while also preventing more serious problems from developing down the line. If you suspect that your bushings may need replacement, don't hesitate to contact PM Autoworks to have them inspected by a professional mechanic.

Oil Changes: Why Is It Important?

Engine Oil: Why is it important?

When we talk about car maintenance, oil changes are at the top of the subject. Why? Engine oil is Vital to the health of the engine & is the life blood that keeps it going. It is the lubrication that the mechanical parts need to keep moving and to stay cool. Without oil the engine will destroy itself from all the friction between the internal components.

What happens if you don’t change your engine oil?

If we don’t change our engine oil on time as per recommended by manufacturers, two things can happen: Oxidation and Contamination of the lubricant. Both of these things can have very adverse effects on the engine as we’ll see why in a moment.

Oxidation is the process in which a substance is chemically combined with oxygen. When you leave an Avocado out and it starts to turn brown, that process is called oxidation. Just like the Avocado, our engine oil is no exception. During normal engine operation, the engine oil temperature increases which also increases the rate of the chemical process. This can result in several problems including….

• Formation of sludge and deposits that reduce engines efficiency and increase the risk of engine failure

• Increased oil viscosity which reduces mechanical efficiency and fuel economy.

• Additive depletion, reducing the effectiveness of the oil

To fight against oxidation manufacturers are now switching to Synthetic oils which has a much higher resistance to the chemical process. This is why it is important to use high quality fluids when servicing your vehicle.

When it comes to oil Contamination there are two types: Abrasives and Fluids

Abrasives are the top problem-inducing contaminants because they tend to cause the most damage. These can include dust and dirt that gets into the engine and circulates through the oiling system. Although there is an oil filter to help prevent this type of damage, some particles are small enough to make it past the filter.

Water and Fuel contamination is also an enemy as far as oil is concerned. Water and Fuel can find itself trapped inside oil which has a laundry list of adverse effects. This is especially true if we take short trips without warming up the engine. Water can cause iron or steel parts in the engine to rust which not only causes them to deteriorate, but turns them into an abrasives. Water is also a very bad lubricant and will increase engine wear if to much is present.

What does this all mean?

If you want to keep your car running smooth and avoid catastrophic engine failure: Change your cars engine oil as per recommended by manufacturer! For some cars this may be every 3,000 miles and others every 7,000 miles. All in all it’s good insurance. You can change your oil yearly for ~$300 or risk engine repairs up to ~$6,000. The choice is yours.
