Strut mount replacement
The strut mount absorbs road impacts while allowing the strut to turn with the wheel.
Symptoms
- A characteristic knock near the strut over small bumps.
- A crunching sound when turning the steering wheel.
What's included
- When its rubber deteriorates, a characteristic knock appears near the strut over small bumps, with crunching when steering. This is often mistaken for damper noise and the wrong part is replaced. We remove the strut and assess the mount, bearing and dust boot: these parts wear together, so replacing them individually is uneconomical. The spring must be compressed with a dedicated tool; replacement without it is dangerous. We check wheel-alignment angles after assembly.
Additional checks
- Spring compression with a dedicated tool
- Wheel alignment angles after assembly
Why it matters
This knock is easy to mistake for the shock absorber itself, leading to the wrong part being replaced. The mount, bearing, and boot wear out together, so replacing them one at a time isn't cost-effective.
More details
The strut mount absorbs all the impacts from the road and at the same time lets the strut turn together with the wheel. When the mount's rubber breaks down, a characteristic knock appears near the strut over small bumps, and a creak is heard when turning the steering wheel. Many people mistake this sound for a shock absorber knock and replace the wrong part. We remove the strut, assess the condition of the mount, the strut bearing, and the boot — these three parts wear out together, and replacing them one at a time isn't cost-effective. We do the work with the spring mandatorily compressed on a special tool: without it, this kind of replacement is dangerous. After assembly we check the wheel alignment angles.
