Car suspensions allow us to feel comfortable inside the car, and for ourselves vehicle is the only way to reduce the natural wear of the articulated parts almost to zero. But sometimes the wrong actions of drivers significantly increase the wear rate of a complex mechanism, especially on bad roads.
1. What is a bad road, and how to extend the suspension life on it
What do we most often mean by the term "bad road"? Some drivers will point to gravel as a poor quality road, others will find the comb that inevitably appears when road repairs are unacceptable.
In fact, only those sections can be attributed to bad roads, on which the height differences of the stepped type, which are critical for the suspension of cars, are most often encountered.
Such obstacles can be like on country roads, where heavy equipment often drives and pushes into potholes in the soft ground, and in the city in places where the road builders stubbornly refuse to do repairs. A striking example of a serious obstacle on a city road is a speed bump, and it must also be passed correctly.
You can save the car's suspension on the roads of not the highest quality in simple ways:
So, when approaching the border of the “Bad Road”, do not rush to slow down sharply if there is no serious obstacle ahead. Remember that driving over bumps on the brakes will kill the thrust bearings, wheel bearings, and many other suspension parts.
When driving a section of rough road, be extremely careful, but at the same time do not trudge like a turtle - suspension on irregularities should work at maximum amplitudes, otherwise silent blocks and racks will fail ahead of time shock absorbers.
When following another car, keep a decent distance if you do not want to get into a hole that has come from nowhere or run into a cobblestone, which modern suspensions do not like very much.
There are situations when a hole still appears on your path, and you can’t go around it. In this case, use the planning effect. Without slowing down, just before the pit, sharply press the brake pedal and immediately release it. The front of the car will first lower, and then rise a few centimeters, and the front wheel will slip over the pit with little or no load and without any harm to the suspension.
If you live in an area where country roads predominate over tarmac, lower your tire pressure, but not by much. With a recommended pressure of 2.0 atm, you can safely lower it to 1.8 atm. The suspension will receive additional shock absorption, and the tires will not experience increased wear.
Well, you can always find a better road, and even if it is a little longer, believe me, you will beat off the cost of gasoline in full on the saved suspension resource.

2. Helpful Hints
On an ordinary dirt road, the speed of a car can reach 70 km / h, and if there are no obstacles on it, then nothing will happen to the suspension of your car. But aggressive driving on a road with potholes, cracks and bumps will not lead to anything good.
If you drive too slowly along country roads, wanting to keep an important knot, the suspension will feel any, even the smallest bump, which will inevitably lead to premature wear.
In addition, when operating in narrow ranges of amplitudes, lubricant is unevenly distributed in ball bearings, as a result of which metal parts can begin to “eat through” each other, creating play. The same applies to shock absorber struts, in which, when metal is worked out, in a small area of \u200b\u200bthe rod, the rubber of the seal can bite, and this usually leads to oil leakage.
But at the same time, one should not forget about the negative effect of sub-zero temperatures on the suspension elements when starting to move on a bad road. Solidified oil in shock absorbers and undeveloped rubber seals in silent blocks during a sharp acceleration on bumps will create critical overloads for all the suspension as a whole, which will negatively affect the whole node.
Sometimes other factors that do not depend on the driver lead to premature wear - for example, a lost wheel balancing, lack of camber adjustment, or suspension parts that already have marks wear. On bad roads, these factors exacerbate the situation several times.
If we remember that an automobile suspension is a single mechanism consisting of many different parts, it becomes obvious that even slight play in steering tips, levers or thrust bearings will create a dangerous runout that disables other elements pendants.
Do you often drive on bad roads? Do not forget to diagnose the condition of the suspension at least once a year, replace worn parts with high-quality original spare parts, balance the wheels and adjust their wheel alignment. These are actually simple steps that will allow your car's suspension to work for a long time and without incident.
Many drivers (including beginners) are not without reason afraid for the suspension of their cars. What are The main fears of novice drivers?
