The devices work on hydraulic pumps that control the impact the car makes against the road. You will notice that an off-road vehicle will not pick up small imperfections on the road because it has such a powerful device. It also ensures that you have proper braking response to avoid hectic accidents.
Checking your shocks should be done if you dive during heavy braking, hit bumps very hard, or the car is leaking shock fluid. Normal driving can also affect the quality of the shock absorbers over time.
You may need a spring compressor to remove the springs on the shock absorbers. The compressor is necessary if the springs are interrelated or integrated. You will need to be careful when doing this as the springs are loaded with high pressure and sudden releasing could be dangerously damaging.
Using a jack stand to lift the car will help you when replacing the parts. You will need to lift the one side of the car at least thirty centimetres off the ground to make the process easier. Similar to changing the tyre, you will need to remove the wheel too. You will be able to see the shock absorbers as they look like springs. This is where you will need to use the spring compressor for safe removal. You will also come across three bolts that will need to be removed using a socket wrench.
Installing new parts is the simple part. You will need to use a torque wrench when tightening the bolts to ensure stability. Putting the wheel and tyre back in place will complete the replacing of the shock absorbers.
It is important that you take the car for a slow drive to test the stability of your work. If you start to notice strange sounds it would be wise to have a mechanic check out the problem. Wiggle the car and go over humps as well to test if the shocks have been installed correctly.
