Strut mounts connect suspension struts to your vehicle. The mount is placed between the vehicle and the strut. As strut mounts age, the insulating material in the mount becomes thinner, which increases cabin noise and allows more vibrations to be transmitted to the cabin. In addition, with age the bearing portion of the mount wears, which compromises the effectiveness of the connection between the strut and the vehicle. In fact, the bearing plates on some struts play a role in steering by serving as a steering pivot. Therefore, worn strut mounts can impact handling. Sometimes a visual inspection of the strut mount can indicate wear. You want to look for any signs of corrosion or damaged components. Worn strut mounts can also cause clunking noises, excessive vibration, unusual tire wear, problems with tire alignment, and changes to a vehicle’s steering.
