1. What are Suspension Strut Mounts and Bearings?
Suspension strut mounts and bearings are vital components of a vehicle’s suspension system, especially in cars with MacPherson strut setups. According to a study by the University of Michigan Transportation Research Institute, vehicles with well-maintained suspension systems experience 20% better handling and stability. Let’s break down their roles:
- Strut Mounts: These connect the top of the strut assembly to the vehicle’s chassis. They provide a cushioning effect, reducing noise and vibration transmitted into the cabin. Mounts also allow the strut to pivot, which is crucial for steering and handling.
- Strut Bearings (or Upper Strut Mount Bearings): These bearings sit within the strut mount and allow the strut to rotate smoothly when you turn the steering wheel. They reduce friction and enable the steering system to operate efficiently.

2. Why is Checking Strut Mounts and Bearings Important?
Regular inspection of strut mounts and bearings is essential for several reasons:
- Safety: Faulty strut mounts or bearings can compromise steering control, leading to potentially dangerous situations, especially during emergency maneuvers.
- Ride Comfort: Worn components can cause increased noise, vibration, and harshness (NVH), diminishing the overall driving experience.
- Tire Wear: Misalignment caused by bad strut mounts can lead to uneven and premature tire wear.
- Suspension Component Longevity: Addressing issues early can prevent further damage to other suspension parts, such as struts, shocks, and tires.
3. What are the Common Symptoms of Failing Strut Mounts and Bearings?
Identifying problems early can save you money and prevent further damage. Here are some telltale signs:
- Noises:
- Clunking or Knocking: Often heard when driving over bumps or turning at low speeds.
