I try to be here most weekdays and some weekends. If you respond and I do not respond back right away I will do so as soon as I can.Did they checked the springs and rubbers? Thanks in advance.
Dear customer if it is just limited to rigorous surfaces is a problem of suspension, but the truth dear customer suspension problems can not be solved simply by observing below the car. We have to apply a disarm or use a special suspension vibration machine.
A vibration machine is a machine where you ride the vehicle and begin to vibrate by the wheels this throws a reading like an electrocardiogram. What measures the vibrations, when the vibrations leave the normal range you will effectively be in a problem in one of the suspensions as the test is done by independent wheels or wheel by wheel. You will notice through this machine which is the one that has the disadvantage.
I understand in your query that they verified the suspension and its rubberss but there are some rubberss that are a bit complicated to visually verify them. They are the supports of the upper and lower part. These rubbers actually fulfill the function of remove noises, or simply absorbs the noise that can be produced when it hits metal with metal. Normally these are the main cause of noise in the suspension, I do not know how they did the verification but the best thing is always to disassemble to observe the state of the rubbers in a good way.
Also dear customer, another aspect that can cause noise and can not be verified with a single view is the same shock absorbers or springs. Remember that they have a hydraulic fluid inside. Not only fluid leaks. If there may be pressure loss which causes noise, so it is important to verify the suspension very well not only visually. The suspension tester equipment can help you minimize the work by indicating precisely where the suspension is producing the sound or the strange vibration.
Have you understood dear customer?
