Tie rods are car parts that are a crucial part of your steering mechanism. Known as track rods in the UK, they connect the steering center link or rack gear to the steering knuckle. This then means they run under the car and shorten and lengthen in coordination with the turns of the steering wheel in order to ensure that the wheels face in the same direction as the driver intends to drive.
In fact tie rods are not specifically car parts but instead the term is used to refer to any narrow rods with tensile strength. The radius of the tie rods when compared to their length means that they are strong in terms of tensile strength but would buckle under any other kind of pressure. Other uses for tie rods are in the spokes of tires or in suspension bridges, though these are of course different in a number of ways to those used in cars.
If a tie rod needs replacing then the steering of the vehicle may wander or become erratic and tires would wear more quickly. It is thus necessary for them to be checked yearly and replaced when required.
One of the most common things that a mechanic checks for in a car that needs servicing is the wheel bearings. These tiny parts are very important in ensuring that the car keeps running safely and that the wheels are performing at a good level without any immediate danger of wearing out. This is important because sometimes the wheels tend to lose steam midway and suddenly get faulty. Proper wheel bearings will ensure that such a thing does not happen at any time. They may be tiny parts, but are still very important parts which ensure smooth running of the car.
That is why you should take proper care of your wheel bearings and have them checked regularly by the mechanic whenever you take the car in for some repair or checkup. Regular checking of the wheel bearings will help keep them in good condition and if there is any damage detected, they can be replaced very soon, without having to wait for the damage to show any effect. So always remember to get your wheel bearings checked so that they remain in top condition and your wheels can be running on and on for a long time to come without any sort of problems whatsoever.
Make sure that your tires are all at the right pressure level. To do this, visit your nearest petrol station and they should have a tire pump – some are free while others require a small fee to run. Unscrew the cap on the tire, and attach the nozzle of the pump to the tire this way. As soon as the pump is on the valve then it should display the pressure a read out. This will be in 'PSI' and you should have all your wheels at around 60PSI though this may vary (consult the manual that came with your car). If the area you were feeling vibrations in coincides with a tire low in pressure, then you will very likely have identified the problem. You then hold the trigger to fill the tire with air, and release it to get the read out as you go. Try to ensure that all of the tires are at the same level and that they are sufficiently topped up.
If you feel that your car may have problems with the suspension parts, then you should try to feel where precisely in the car these are coming from. One way to do this is to try to focus on the feel of the car as you drive. You might hopefully be able to feel the difference in the suspension parts. A tip is that if the vibration is coming through the steering wheel and you feel it in your hands, then you probably have a problem with the suspension at the front of your car. However if the vibration is coming through the seat, then it is probably coming from the back of the car. If this is the case then you should go and have a look at the area to start with.
The first thing to look at is your wheel in the affected area. Often people will misdiagnose their suspension as having problems when it is their wheel that has problems in reality.
If you have damaged suspension then it is important to purchase suspension parts in order to repair it. Your suspension is the part of the car that enables the wheels to take the car's weight while providing a smoother ride than a simple metal pole would do. This is achieved through the use of many types of suspension parts such as large springs that act as shock absorbers or pistons. These then keep the car at roughly an equal height even when the car is driving over bumpy terrain and prevents it from bouncing and jerking around which would create an uncomfortable ride and further hurt the driver. This also helps to keep all four wheels in contact with the ground for as much time as possible which is also very important.
It is highly important then to repair your suspension and to replace suspension parts when necessary as otherwise you might cause more damage to your car, or increase your chances of rolling the car as one side will be raised more highly than the other. This can also interfere with steering and put you at greater risk of a flat tire.
