If you have a car that has front-wheel drive, chances are you have struts on the front-end suspension. Struts are a combination of various front-end components that includes shock absorbers, coil spring, steering knuckles, spring seats and strut bearings.
Struts are the connecting link between the upper strut bearing and the lower ball joint. Struts are usually gas charged, and they absorb the wear and tear of over-the-road travel. Over time struts wear out and need to be replaced. The front end of a vehicle should be examined by a professional mechanic before making a final decision.
Signs of Wear
Signs that your car might need new struts include bottoming out on bumps, cupped tire wear, swaying and obsessive bouncing. If you believe your struts are bad, you should have the vehicle checked by an experienced front-end or suspension mechanic. After struts are changed a new front wheel alignment is usually necessary.
According to Cost Helper, replacing struts cost between £195 and £455, including the price of labour. If you have a luxury car the price goes up to between £455 and £650; and if that luxury car is a Lexus the cost can still rise even more.
