It is the car suspension on roads that has an increased load, which often leads to various kinds of breakdowns and the need for scrap cars brampton. At the same time, even on relatively new foreign cars, the car owner can independently check the suspension and repair it, which will save some money on the operation of the car.
Experts advise to carry out constant checks and preventive examinations of the car’s suspension on a lift or a pit in the garage, this will allow you to identify existing faults in a timely manner, fix them in time or contact a service. If you neglect such a regular inspection, in the end, complex and expensive car repairs will be required.
All parts in the car’s suspension are interconnected, so the appearance of wear or breakdown of individual parts will lead to serious problems and failure of other chassis elements. Therefore, you should not delay the repair, and auto diagnostics, albeit independent, should be carried out every 2-3 months of car operation.
Suspension design features
Structurally, the suspension of cars can vary significantly, depending on the class of the car and the specific manufacturer. The most widespread today is the independent front suspension, made according to the McPherson type, as well as semi-independent at the rear beam. This design provides good handling, at the same time increases the reliability of the car, provides comfort even when driving on bumpy roads.
On some cars today, air suspension is used, which provides the highest possible comfort on board. At the same time, the design of such a suspension is extremely complex, often when it fails, expensive repairs are required, and the cost of restoring a car can shock even a wealthy car owner.
Suspension Self Test
You don’t need to use any professional tool to independently check the car’s suspension, all you need is to drive the car onto an overpass or garage pit. If there is an engine sump, it is also recommended to dismantle it, which will allow access to the suspension elements and easy inspection.
It is recommended to start work with the front suspension, the upper supports of the struts are checked, while the car does not need to be lifted, but the suspension must be loaded. The gap between the body and the cup should be no more than one and a half centimeters, with a larger gap, replacement of the upper pillows is required. If the check is carried out in a garage pit, the car should be rocked, thereby checking the condition of the shock absorbers.
Directly when inspecting the shock absorbers, they check that they have no mechanical damage, damage to the anthers and oil leaks. To check the steering linkage, swing the suspended wheel left-right and up-down. The presence of knocks may indicate wear on the tips or tie rods. Such extraneous sounds when the wheel is rocking may indicate wear on the ball joint. Also, the ball joint can be checked with a pry bar, if there is a play, it should be replaced.
To check the wheel bearing, a suspended wheel is rotated; the appearance of a grinding or humming sound may indicate a problem with the hub bearing, which must be replaced as soon as possible. The condition of the silent blocks is checked with a pry bar, for which the levers are squeezed with a mount in the transverse and longitudinal directions. The presence of a backlash indicates wear on the silent blocks and the need to replace them.
Checking the anti-roll bar is performed with a pry bar, which is inserted between the stabilizer and the subframe, after which the connections are actively pumped and the presence of backlash is monitored. The stabilizer can dangle if there is wear and tear, in which case it is necessary to replace the stabilizers and worn suspension elements.
Rear Suspension Check
By its design, the rear suspension is much simpler than the front one, and accordingly it is much easier to carry out its independent diagnosis. It will be necessary to check the condition of the silent blocks and springs in the beam, shock absorbers and wheel bearings. The springs are inspected for damage; if the coils are cracked, the springs should be replaced in pairs. The shock absorbers are inspected for oil leaks and damage to the stem, and the machine is also rocked to determine the amplitude of vibrations and to determine if the shock absorbers are worn out.
