Bushes in a car work like knees or elbows in the human body. They absorb the shocks from bumps and divots in the road, prevent metal-to-metal contact and control the movement of the joints within the car. Without the protective materials, unwanted friction is caused between two hard surfaces and the joints don't move as freely or smoothly as they should. When the rubber suspension bushes in cars wear down, which is inevitable over time, the driver will notice how uncomfortable the ride can become through clunking and unnatural movements in the steering, particularly while cornering. Choosing quality bushes will bring you peace of mind and a longer lasting solution when you need to purchase replacements.
