It is most convenient to replace silent blocks with a special tool (puller), but you can do the work with improvised means.
You will need a silent block remover or mandrel.
1. Mark or remember the location of the silent block in the lever to install the new silent block in the same position.
2. Install the beam in a vise and press out the silent block with a mandrel of a suitable diameter or a puller.
Note. If it is not possible to press out the silent block, saw it with a hacksaw. The fit of the sawn silent block in the lever eye is significantly weakened.
3. Remove the silent block from the eye of the beam.
4. Clean the eye from rust and scale, press in a new silent block, orienting it in the same way as the old one was installed, and press it in with a mandrel.
5. Similarly, replace the second silent block.
6. Establish a beam of a back suspension bracket on the car. Bolts of fastening of a beam to arms finally tighten on the car standing on the ground.
