Why Replacing Worn Silent Blocks Doesn’t Always Solve Suspension Problems
Many experienced car owners found a time when not only components and assemblies, but also a huge number of parts were restored and not changed. The same levers that rubber silent blocks are pressed into at the factory were previously repaired. Why is such an operation no longer relevant now? There are more than good reasons for that.

The shortage in the spare parts market has long given new life to seemingly forgotten actions: the brake mechanisms have been sorted out, the brake pads have been renewed, the discs have been milled and machined, and the silent blocks in the levers have been replaced with new ones. For the owner – a serious help and savings: for example, the original brake disc costs 26,000 rubles for an average Japanese SUV. The groove is in a thousand. Feel the difference, as they say.

Of course, experts will say that machined discs don’t come out as often as new ones, and in general they can start to kick the pedal after the first pee. But the price difference is 26 times, and that says enough.

Wishbones are also subjected to restoration procedures: in three cases out of four, the cause of failure is a worn silent block, which is torn from hussar passages by potholes and potholes. And sometimes – and just from time to time. The “chewing gum” is pressed into the handle at the factory with the help of special equipment, and the operation is performed “hot”, so simply pulling it out, as with the good old “Japanese”, will no longer work.

Our craftsmen guessed that they would burn out the old and put in the new. Brilliant! But no. Fifteen years ago such a “joke” could have passed, but today it no longer exists. And the reason for this is the material from which the suspension is made.

For now, until 2007-2008, everyone was using metal that could be burned, beaten, or stabbed, and nothing terrible happened. With him the trick “burned-put-a new one” succeeds and the part will disappear. But after the world went by the embossing scheme, aluminum became the main suspension material. “Winged metal” will not allow such impudence, and the silent block installed in the lever simply falls out after a few hundred kilometers. Do masters know about it? Of course they know – they’ve tried more than once, the result is the same.

But on the other hand, it is damned difficult to refuse the owner of, say, a Mercedes-Benz, who is offered to buy a pair of new levers for 40,000 – 50,000 rubles – what I read on the forums about the possibilities of suppression. Since the owner is willing to take responsibility, has brought the parts and is paying for the work, why not take it? And the fact that after a hundred or two kilometers the suspension starts to “click” again, giving loud blows to the steering wheel, is the problem of tomorrow.
