Causes of difficult steering

Causes of difficult steering wheel

1) Bad Steering Rack – The steering rack is made up of the pinion and rack. A series of U-joints and shafts keep the steering rack attached to the steering wheel. The steering rack will eventually become worn out and damaged from simply using your vehicle. You will know when this happens if your steering wheel is only stiff after you’ve started your vehicle. As the engine stays on longer, the steering rack will get hotter which causes the lubricant to settle in more. Therefore, the steering wheel may become less stiff as the car continues to run. But still, get the rack replaced before the problem escalates.
2) Broken  Belt – One of the most common causes of steering wheel stiffness is when the serpentine belt is damaged or cracked. This belt is constantly being used when you drive the vehicle so over time, it gets worn down pretty quickly. Then it will become loose which is when the stiffness in the steering wheel will begin. If you don’t replace the belt soon, it will break altogether and then you won’t be able to move the steering wheel at all. It is better to replace the belt before this happens.
3) Leaky Fluid – Perhaps the top cause of a stiff steering wheel is when you don’t have enough power steering fluid in the system. Usually, this occurs if the fluid is leaking from the pressurized hose area. Sometimes the hose will get cracked or simply become loose, causing the fluid to leak out. Since this fluid is needed to pressurize the system and lubricate the pump, you will have a stiff steering wheel if there isn’t enough fluid to perform these tasks in the system.
4) Pump Failure – The pump of the power steering system is what produces the amount of pressure needed to allow you to smoothly turn the steering wheel. If this pump were to stop working, then it will become more difficult to turn the steering wheel. Normally, in these situations, the pump won’t prevent the steering wheel from moving completely. You will still be able to turn it, but it will require a lot more force on your end.
5) Thick Fluid – The power steering fluid can become thicker over time. If you don’t change your fluid regularly, then it will become too thick to lubricate the system. This will cause more stiffness in the steering as you try to turn at low speeds. Therefore, you need to drain this old fluid out and replace it with entirely new fluid.

Shock Absorbers

Essentially, shock absorbers do two things. Apart from controlling the movement of springs and suspension, shock absorbers also keep your tyres in contact with the ground at all times. At rest or in motion, the bottom surface of your tyres is the only part of your vehicle in contact with the road.   When to replace shock absorbers: Longer stopping distance Having worn shock absorbers on your vehicle can increase your stopping distance by up to 20%. As you increase your traveling speed this will also increase the distance it takes your vehicle to completely stop. This 20% extra distance can be enough to cause a fatal incident and should be attended to as soon as possible. Swerving & nose-dives Does your car dip or swerve under braking? If so, you need to have your shock absorbers checked. If you do dip or swerve under braking it decrease your control over the car which can be very dangerous in wet weather. Vibrations Are you getting vibrations through ...

Car Radiator Care

  Car radiator  is one of the key components in a vehicle’s cooling system that is often overlooked. In the automotive world, the radiator can be likened to the heart of the cooling system. Just as the heart pumps blood throughout the body, the radiator ensures that coolant flows through the engine, keeping the temperature at a safe level. Without a healthy radiator, a car engine can overheat, causing costly damage and disrupting your driving pleasure. Therefore, in order to keep your car running at an optimal temperature, it is important to understand the role and take good care of the radiator. In this article, we will explore more about car radiators, from their functions, components, and the best way to maintain them. What is a Car Radiator? A car radiator is a part of a car’s cooling system that is responsible for regulating engine temperature.  Without a radiator, the engine will overheat, causing serious damage and shortening the life of the vehicle.

So, There are dozens of problems that can lead to excessive fuel consumption, some of them are serious and some can be easily corrected. Consequently, Identifying the reasons your car has excessive fuel consumption and correcting them will save you money and help you to avoid costly repairs. Excessive fuel consumption can also be an indicator of a much more serious issue that if left, can develop into an expensive repair. Did you know that a vehicle can burn up to 30 per cent more fuel if proper maintenance is not performed on a regular schedule? As a result, Familiarizing yourself with the more common causes of poor fuel economy is a smart way to help keep your car running as economically and efficiently as possible. We all know the importance of regular car maintenance, but for many reasons, we just don’t do it often enough. Cars use the most fuel during initial acceleration, so if ...
