One of the possibilities is that it is the suspension turret, depending on the country, it can have different names such as Casholeta. The same is the one that is subject to the suspension spring from the upper part, together with the shock of the shock absorber, many times when this piece is damaged, you notice it before large blows and it is even difficult for you to locate the problem if you do not disarms it since, no matter how much palanques trying to verify strikes may not be noticed. To replace the workforce is the mosma that would cost you to replace a shock absorber. On the other hand, if it was not a gang of grills or stabilizer bar, but all this is located by raising the vehicle and palanqueando with a bar each suspending sector. Greetings and luck
