Is it dangerous to put a “restored” suspension on a car?

Now that there is a shortage of spare parts and the price is rising, many car owners pay attention to remanufactured spare parts. Some craftsmen even guarantee it.
Now that there is a shortage of spare parts and the price is rising, many car owners pay attention to remanufactured spare parts. Some craftsmen even guarantee it. Now there are many such spare parts on the car market, especially for the chassis. The AvtoVzglyad portal tells whether it is worth paying attention to the cheap parts.
On many modern cars, suspension repairs have already caught up with the “capital” of the engine, so the installation of remanufactured parts for the chassis is becoming increasingly popular. It remains only to understand which parts are worth putting on the car and which are not.
Let’s start with the wishbones. On expensive foreign cars they are made of aluminum. As a rule, they are very strong and it takes a very hard blow to damage such a lever. But if there is damage to the repaired levers (for example, from welding), it is better not to buy such a part. The fact is that the structure of the metal has already broken, so the spare part will simply crack from a repeated blow. So it makes sense to acquire levers only on disassembly and carefully examine them for external influences.
Much more widespread is the recovery of ball bearings by polymer casting. This polymer fills the space between the liner and the cap. The polymer presses on the liner and presses it down. Therefore, if there was play in the ball, then it disappears. It seems – here it is, the way out! Do not rush, because there are many nuances. The polymer will not fill all the space. And the ball in the support should not be rusty, and the factory liner should not be worn out. Only in this case, the ball will last about 30,000 km.
But if the ball is rusty, under load it will “nibble” even more what’s left of the factory liner, eventually getting to the ball body. As a result, there will be slack in the movement and in the worst case, the part may simply fall apart. Unfortunately, when buying such spare parts, it is impossible to see that the ball at the support is already covered with “saffron-milk mushrooms”. You have to believe the word of the seller, and that brings a lot of problems.
Another common procedure is shock absorber repair. Here you should pay attention to the products of companies engaged in tuning. They make folding shock absorbers, which are the easiest to repair. The rest is more difficult. Koni FSD, for example, is very complex. In theory they can be repaired, but the shortage of spare parts makes such a restoration impractical. And the shock absorbers that provide automatic maintenance of the height of the body are not repaired at all.
In general, before going to a car service, you should study the material of your car. Rebuilding shocks usually consists of replacing seals, valves and rods. The latter can be selected from the ones used. They also change the oil. The main thing is that it should be designed for freezing temperatures – “minus” 50 degrees. In reality it appears to thicken at -40C, but it is still pumped up.
