Shocks and Struts – And Other Suspension Components

Auto Repair Shop in South Windsor CT explains about the components of a typical suspension system that need to be checked regularly

SHOCKS and STRUTS

Shocks should be checked for proper operation, damage and leaks. If the actual shock absorber is damaged, it can’t move up and down properly and absorb the bumps in the road. Leaks of the hydraulic fluid show up as the shock being wet and/or oily. That fluid cannot be replaced and the entire shock has to be replaced.

Shocks and Struts plus other suspension parts explained

STRUTS

Struts are used on some vehicles in place of shock absorbers. They look like a shock with a spring over top. The struts act to stabilize your vehicle and keep it from swaying, bouncing and bottoming out while absorbing the bumps from the road.

TIE RODS

Tie rods are part of the steering mechanism of your car. Tie rods help push and pull the front tires as the steering wheel is turned. They play a key role in the performance of your vehicle’s steering – and your safety. Faulty tie rods can result in erratic steering, wandering and significant tire wear.

BALL JOINTS

Many of the front-end sounds and clunks that you may hear can be symptoms of ball joint failure

The ball joint is the pivot between your vehicle’s wheels and its suspension system. This means they’re also critical to safe steering. Clicking. Snapping. Squeaking. Many front-end sounds are often symptoms of a bad ball joint.

Because these joints link your vehicle’s wheels to its suspension system, driving around with faulty ball joints is really a safety hazard. Come in to Big O Tires for an inspection today.

RACK AND PINION

Your vehicle’s steering system relies on the rack and pinion to make steering feel ‘tight.
Rack-and-pinion steering is quickly becoming the most common type of steering on cars, small trucks and SUVs.

The rack-and-pinion gearset does two things. First, it converts the motion of the steering wheel into the motion needed to turn the wheels. Second, it provides a gear reduction, making it easier to turn the wheels.

Simply put, your vehicle’s steering system relies on the rack and pinion to make steering feel ‘tight.’ Bring your vehicle to Big O Tires for a diagnosis of your steering system.

CV JOINTS AND CV AXLES

If you hear clicking noises when steering or making a turn, it’s probably because of a problem with your car’s CV joints or CV Axles. These components parts are found on all Front Wheel Drive (FWD) cars and some Rear Wheel Drive (RWD) cars.

CV stands for Constant Velocity. The CV Joints and CV Axles are found inside a rubber casing called a CV Boot.

Understand that torn CV boots and worn CV joints or axles can cause damage to transmissions and other components.

Shocks Worn Out?

HOW CAN I TELL IF SHOCKS AND STRUTS ARE WORN OUT?

Although this test in not intended to replace a proper inspection by qualified technician, it will give you an idea regarding the wear of either shocks or struts.

Here’s a few things you can do to check yourself. But use caution – this is not intended to be a replacement for a proper inspection of your suspension and steering by a qualified technician.

Push down quickly and firmly on the front and rear of your vehicle. If the car bounces more than once or twice, you may need to replace your shocks and struts.

Some initial signs of suspension problems are:

• Tire Wear: Your tires seem to have excessive or uneven tread wear.
• Leaking: Your shocks or struts are leaking fluid.
• Damage: Your shock or strut casings are dented or damaged.
• Mounts: The shock or strut mounts are broken or worn.
• Drifting: Your vehicle seems to float, sway or drift during turns.
• Rough Ride: Your vehicle bounces excessively when you hit a bump.
• Dip or nose dive: Your vehicle tends to “nose dive” when you apply the brakes.

WHAT’S THE DIFFERENCE BETWEEN SHOCKS AND STRUTS?

What’s the different between Shocks and Struts?

Shock absorbers are more common on trucks and SUV’s while struts are usually found on cars. The shock absorber cushions the bouncing of the wheels using nothing but hydraulics.

On the other hand, struts are a little more complex. They absorb the shocks by combining steering elements and support for the vehicle. At first glance, struts appear like a shock absorber with a spring on top.

Typically, when it comes to cost, struts are more expensive to replace. That’s because they’re a more complex part.

Regardless of what your car has, shocks and struts cannot be interchanged. If your car was built with struts – then they have to be replaced with struts. You can’t switch from struts to shocks.
