Considering the broken roads, it is the suspension that is under considerable strain. It is necessary to perform its diagnostics on a regular basis, replacing worn parts, which helps maintain the technical condition of the car. It is often difficult to do the diagnostics without an elevator, and many car owners simply cannot afford to go to the service every 5,000 – 10,000 km and have their car checked professionally. Let us tell you in more detail how to independently without an elevator to perform diagnose suspension of the car. If the car is not running, it makes no sense to do it. It is more profitable to recycle such a car: https://towingandscrapcarremoval.ca/scrap-car-removal-oshawa.
How to check the car’s suspension without an elevator?
Do-it-yourself car suspension diagnostics
It is not necessary to perform diagnostics of the suspension of the car on a special elevator. Professionals completely refuse to use such lifting devices, as an unbalanced car is impossible to check for knocks in the suspension and rock the car, also there are difficulties with determining backlashes in the joints of struts and ball joints. That is why it is better to check suspension on the car, which is standing on the ground.
For such a self-check, you can use trestles or inspection pits in the garage. If possible, the diagnostics should be performed with an assistant, who will rock the car, and the second person will directly in the observation pit observe the behavior of suspension and determine the appearance of knocking and play. If the initial inspection reveals backlashes and knocks, an in-depth diagnosis is necessary in such a case.
All suspicious joints are squeezed from the parts to determine their degree of wear and to determine the need for replacement. To squeeze the bushings stabilizers and silent blocks you need to use mounting spatulas or suitable tools. You will need to visually assess the condition of the rubber joints, it is such rubberized elements from the constant shock and vibration quickly wear out, and without timely replacement, they significantly worsen the condition of the entire suspension.
It is even possible to check some parts without examination pit, for example to check front struts they put palm on the central part of shock-absorber or support bowl, and at this time the other person begins to rock the automobile. Vibrations should quickly fade if shock absorbers are in order. To check a condition of upper shock absorber pads and availability of bushings backlash one should jerk the body of such parts with his hands, and if backlash is noted, their replacement is required.
The simplest way to independently check the suspension of a car
Self-diagnostics of the suspension of the car will allow you to determine the existing faults with silent blocks, ball bearings, various guides and rods. Such checks can be performed on the pit or a wheel well, the work is better to do with an assistant, who will swing the body, which will assess the condition of shock absorbers and the presence of play in suspension components. Specialists recommend performing such self-diagnostics every 2-3 months, which will allow detecting existing defects in time and eliminating them in time.
