The shocks and struts functions
The shock absorbers as well as the struts of your vehicle generate a resistance to forces created by the up and down motion of the suspension. The main function of the shock absorbers is to prevent your vehicle from bouncing when it faces obstacles. By transforming the kinetic energy of the suspension movement, the shock absorber adapts to road conditions. Concerning the struts, they perform a damping function, just like shock absorbers. Both shocks and struts keep your tires on the road, and your tires are what connects your vehicle to the road and allows you to safely handle your car through turns, over bumps, and even stop in time.

What are the signs indicating faulty shocks and struts?
When your shocks and struts are worn, your tires bounce successively over bumps. Your vehicle will wallow through corners, your front end will dive when you stop, and your rear end will squat when you accelerate. All this hurts your ability to control your vehicle. Worn shocks and struts stress suspension and steering components, and ruin tires prematurely.
If you notice part of your vehicle’s riding low or if you hear scraping or knocking on uneven roads, it’s time to visit John’s Thistle Auto!
How often do you need to maintain your shocks and struts?
Proper maintenance according to the manufacturer’s recommendations means having your suspension inspected regularly and repairing or replacing it when needed.
Proper suspension maintenance includes regular (at least once a year) inspections to look for hydraulic fluid leaks in the shocks and damaged parts that may need to be replaced or repaired. We recommend having a certified John’s Thistle Auto technician perform all suspension inspections and maintenance. They have the expertise to detect any anomalies and the skills to repair or replace any defective parts. Experts recommend replacing all four shocks at the same time, so that handling is even in each wheel. The normal lifespan for shocks is roughly 80,000 km.
When well maintained, the suspension enhances passenger comfort and allows you to maintain proper road handling. Besides, a suspension that’s in good condition will make your tires last longer and ensure the steering functions properly.
