How to choose a ball joint for a car?

Hello. Almost everyone at least once saw on the side of the road a car with the front wheel turned out on one side. First of all, this malfunction arises from the “flying” of the lower or upper ball bearing. Let the details of these small, but their breakdown when jerking from the ground or even “jump” on a small pothole fraught with “loss” of the wheel and a serious accident. The primary “symptoms” of faulty ball supports are knocks in the front of the car when driving on an uneven road at speeds from 5 to 40-50 km / h. At the same time, extraneous sounds are repeated on every hummocks and holes and resemble drum rolls. After the wear of the ball fingers reaches the limit, they simply jump out of the socket and thereby deprive the wheels of the axial support. Next – how lucky. At high speeds, the denouement can be very tragic. And therefore, with particular urgency, the question arises of buying real, not burnt poles. First of all, the attention of various kinds of dodgers is attracted by ball supports for “Zhiguli” and “Samar”. The real “Belebey” finger is represented primarily by the absence of traces of the turning tool on the body and the uneven dirty gray color of the conical surface as evidence of heat treatment. Manufacturers of the same “left” ball joints grind their fingers on conventional lathes, and there can be no question of any heat treatment of the part. The surface of the fake is smooth, the emblem of the manufacturer and the sign of conformity to Russian standards are missing on its body. Quite often in the car market, one can also find “left” ball bearings of the “BelMAG” association from the city of Magnitogorsk. A sign of these details is a hologram on the body and an individual packing box of red or steel color with a set of fasteners. In order to protect motorists from buying a “left” ball joint, we will give some more tips on choosing this important detail. The ball should be forged, gray in color without any paint; thread rolling, not cut on the machine; the body halves are always carefully welded, and the weld points are visible only on one of the cups. In addition, pay attention to the shape of the lid with a slit, which should have a qualitative hemisphere in the profile.
