Front axle shock absorber mount for Opel Vectra C — TA Technix

The strut mount is the upper anchor point of the shock absorber: it supports the weight of the front end and allows the strut to pivot when steering. A sharp cracking noise when steering while stationary is caused by its bearing.

Competition versions replace the rubber with a bearing and a rigid connection: direct feedback, zero flex, and sometimes integrated camber adjustment - plus everything the shock absorber absorbs is transmitted into the body.
