Shock Absorbers

   

When To Replace Your Shock Absorbers

Shock absorbers [or struts] play an important part in your vehicle’s suspension system. You need to replace them when certain signs of wear becomes evident, otherwise your safety and comfort can become compromised.

A shock absorber works by “damping” the compression and extension of the vehicle’s suspension springs to prevent ongoing bouncing. Shocks work to soften road impact, prevent excessive rebound, limit sway, and improve overall road handling. When your shocks are working properly your car holds the road whether you are braking, negotiating a bend in the road, driving on bumpy roads or experiencing strong side winds. When worn out, shocks can contribute to you losing control of your car putting you, your passengers, and riders in other vehicles in grave danger.

There are a variety of companies producing replacement suspension parts, three are highlighted here:

kyb shocks is the largest supplier of shocks and struts to vehicle manufacturers in the world. Their line up of shocks cover the entire gamut from replacement to upgrade to performance shocks and struts.

Perhaps the most well know name in the business is Monroe, Amstrong, and Gabriel Founded in 1916 when cars still rode on carriage springs, Monroe invented the first shock absorber and the company has been innovating ever since.

Tokico shocks are probably less known to consumers, but they are a favorite for those who want a unique combination of ride, adhesion, and handling.

So, when should you replace your shocks? Every 50,000 miles as one manufacturer suggests? Well, it might be earlier than that if you regularly drive on rough roads or much later if your driving is more local, the roads are well maintained, etc.

One way to determine whether your shocks need replacing is to do this simple test:

1. Grab hold of the corner of your vehicle’s bumper.

2. Push down on it as hard as you can.

3. Observe: the bumper should have dropped down, jumped back up and gone down again once. If it continually moves, then that particular shock is no longer effective. Repeat the test on the remaining three corners of your vehicle.

Other telltale signs of shock wear can be observed through leakage [although a leak is not always indicative of wear] and by observing tire wear patterns. Finally, if you are simply experiencing motion sickness every time you go for a ride, then that can be the best indicator that your shocks or struts need replacing.

Suspension Repair

    

Car Suspension System Repairs

A car’s steering system enables the car to turn and its suspension system smooths out the ride. However things can go wrong, making the ride rough or steering difficult or dangerous. This means time to repair. Many types of steering and suspension systems have been used to control cars. Older cars use mechanical suspension that relies on springs and shock absorbers but new cars use hydraulic cylinders called struts. Besides this, many of today’s cars rely on rack and pinion steering. Without proper care, a car’s steering system should give 80,000 to 100,000 miles of smooth turns.

Why The Car Doesn’t Turn Where It Is Turned
Here are some tips for troubleshooting steering and suspension systems:
– If the car’s power steering system growls when turning, then the power steering booster fluid level needs to be checked.
– If the car makes strong squeal, the drive belt on the power steering unit should be checked.
– If the car shimmies, then the tire pressure should be checked for any damages.
– If the car leans hard in corners, the stabilizer and struts should be checked for loose parts and wear.
– If the older car is difficult to steer, then the steering system’s zerk fittings needs lubrication.

For repairing steering systems, follow this guide:
The tie-rod ends have to be inspected, adjusted and replaced if necessary. They connect the wheels to the steering unit. They can wear out if they damaged or worn. Mark the location of the old ones for the new ones to be replaced in the same position.
The steering gear unit has to be inspected adjusted and replaced if necessary. Adjustments can be made to steering gear systems with wrench and screwdriver. Help can be taken from the  service manual. In case of replacement, the steering wheel and column may need to be removed first. The manual has to be consulted as every car is different. The repaired steering system can be checked by taking a test drive.

The car’s suspension system includes leaf springs, a stabilizer bar, a suspension arm, a shock absorber and/or MacPherson struts.
For replacing suspension parts, follow this guide:

First, find out the specific suspension parts of the car. Jack up the car and place safety stands under the wheels. Replace the bushings by removing the brackets holding the bar in place. Shock absorbers are installed inside the coil spring at each wheel and can be replaced by removing the bolts at the top and bottom that connect them to the suspension system. The manufacturer’s instructions have to be followed because shock absorbers and springs are under tension and can cause injuries if improperly removed. Remove the fasteners at the top and bottom that connect them to the suspension system. The car service manual will help in this. Replace the strut as a unit. Many cars have upper and lower suspension arms mounted on rubber bushings. For replacing them, loosen and remove a bolt on which the bushing is mounted.

Car Suspension System

       

Car suspension system is a vital part of your car that allows you control it more effectively. It is the car suspension system that is responsible for ensuring a smooth and safe ride every time you decide to take your car anywhere. An important thing that most car owners forget is that like other parts of your car, the performance of its suspension system deteriorates because of wear and tear.

Thus, the importance of replacing various components (including but not limited to shocks or struts, bushings and springs, and wheel alignment) of your car’s suspension system in a timely manner cannot be overemphasized. A careful look at your car’s suspension system will give you a fair idea about the steps you can take to ensure optimal performance.

Although there are certain (maintenance) tasks that car enthusiasts will want to perform themselves, the more technical (maintenance) tasks such as rotating tires, while setting the alignment and replacing bushings are best left to a professional. Some of the most important parts of a car’s suspension system include tyres, shock absorbers, arms and bushings, ball joints, coil springs, and stabilizer bar link etc. Experts recommend using only original equipment manufacturer parts since the performance of aftermarket parts is inconsistent at best.

What to Check in your Car’s Suspension System?

As clarified above, you do not need a professional mechanic to tell you that your car’s suspension system requires maintenance. You can easily establish as much yourself. Following are the parts you should look at when trying to ascertain if you car’s suspension system needs maintenance;

Tyres – It is vital to keep the tyres of your car in optimal condition. Tyres are the first thing you should look at for signs of wear and tear. Uneven patterns on the front tyres indicate that it is time for wheel realignment; you can rotate the wheels and adjust their alignment. Last but not the least, replace worn out tyres without further ado.
Shock Absorbers – Though the usual life of shock absorbers (also called struts) is several years, this is dramatically reduced by regular driving on uneven roads and paths. Shock absorbers impact the driving stability (including steering and stopping) of your car and need to be kept in optimal condition. Fluid leakage and bobbing of the car once you hit the brakes, and leaning too much into corners while turning are clear signs that your car needs new shock absorbers.
Arms and Bushings – Experts recommend examining the arms and bushings for signs of wear and tear (such as cracking). Wheel shimmy and vibration are clear signs that raise a red flag about the condition and performance of the arms and bushings of your car.
