In the Mercedes 190, due to age, the original springs often burst. Usually the circle is interrupted at the top or bottom. The car lies on its side, it is less manageable. Some still manage to run several thousand miles on broken springs. Therefore, if you hear an unnatural noise behind the car or if it is on its side, you should pay attention to the rear springs and replace them if necessary.

We will change the rear springs on the Mercedes 190 without a special puller, we will use jacks. Of course, this is a dangerous and low-tech way, but few people will buy or make a special tool for an old car.

Choice of springs

The springs were installed at the factory depending on the configuration and, accordingly, the mass of the car. There was and is a point system and springs are selected according to it. Here is a screenshot of the book below, everything is well described there.

Ten head bolts.

4. After removing the arm protection, we have access to the shock absorber, stabilizer bar and floating muffler block.

6. We take a skid and hit the bolt. If not, raise or lower the jack a little. Usually the bolt comes out halfway and then the problems begin. If your bolt is half unscrewed, then you can insert a punch into the hole and guide the silent block, and on the other hand, remove the bolt with your hands.
