Sprung repair

What is car sprung? – it is a complex unit in a car that refers to the chassis and is divided into front and rear sprung. The main function of the sprung is to ensure the safety and comfort of the vehicle. When the vehicle is moving, the suspension dampens vibrations from road bumps. It turns out that the main part of the loads falls on it and it is clear that all the components of the suspension (springs, supports, bearings, stabilizer rods, shock absorbers, support cups) become unusable.

Of course, motorists need to understand that the wear of suspension parts is affected by bad roads with pits and bumps, passing by “speed bumps” at high speed, but the driving style of the driver, as well as the attitude of each car owner to his iron horse, affects no less. It is important to know that any part has its own life cycle and wear period, timely replacement of units and spare parts will help car owners not to start a situation before almost all the components of the suspension have to be changed, which is noticeable in cost. Well, do not forget about safety, a timely corrected problem is the insurance of your life and those around you on the road. Do not forget that the high-temperature climate also leads to rapid wear of rubber joints and silent blocks.

Symptoms such as: body swaying, tapping, noises and squeaks, an increase in braking distance, vibration recoil from the road to the steering wheel, vehicle instability, moving in different directions in a straight line, mechanical damage – hitting an obstacle, falling into a hole, etc. hint the attentive driver that it’s time to visit the car service.

Where to start sprung repairs?

The most important thing, of course, is to understand what exactly is out of order and what is the cause of the malfunction; this requires diagnostics. Although experienced motorists, as a rule, do not delay the diagnostics of the chassis and carry out it during maintenance for prevention, this will help prevent unexpected surprises on the road and eliminate problems in a timely manner.

Also, before making the camber and toe, the auto mechanic must make a running diagnostics, and until the defects are eliminated, the camber and toe will not be performed.

Diagnostics is subdivided into “Computer”, which is used only for vehicles with electronic sprung systems. “Manual Diagnostics” is the old proven old way, where you can see everything with your own eyes, and “Vibrator”, which creates for the sprung – road conditions very similar to real conditions.

Diagnostics of the front and rear sprung of the car is performed.

As a rule, the front sprung is repaired more often, this is due to the greater load on the units in the front of the car, plus the main control units are located in front part.

After a complete diagnostics, the priority work is determined, and recommendations for spare parts are given. It is better to replace shock absorbers and levers with new ones than to repair old ones; when replacing, be aware that they change in pairs on the same axis, as well as brake discs and pads.

Sprung levers fail a little less often (if you do not drive often at speedhumps), but it is recommended to change them even with the slightest deformation, because this leads to a change in camber and toe and abrasion of rubber, change levers in pairs. Rubber parts in the sprung, such as (rod bushings, boot, cover), are replaced with new ones even with minor damage or deformation. Even less often, the air sprung fails with proper maintenance of the system, regular service, but replacing the air struts and the valve block will cost a pretty penny.

Different brands of cars have their own characteristics, so it makes sense to carry out diagnostics and repair of the chassis in proven car services with good specialists and high-quality equipment.

Causes of noise while driving or knocking on the sprung

loosening of the sprung attachment due to heavy wear of the cushions on eyelets snubber and bushings
overloading the rear of the vehicle
Failure of snubbers
wear of bushings located on the sprung arms
Damage or deformation of the spring
Breakage of the compression stroke buffer

The reasons for the appearance of deviations of the car from the trajectory while driving:

Failure of one of the sprung springs or its deformation
Displacement of the rear axle due to heavy wear of the bushings, which are located on the sprung arms
Deformation of the sprung arms

The main causes of air sprung breakdown

Air sprung components are generally strong and reliable. But over time, they can become unusable, and the entire system stops to function.

The most common problems that arise are:

Air bellows fail;
The compressor breaks down;
The air sprung chamber is bursting;
The front air struts are depressurized;
The stiffening valves of the pneumatic supports are damaged.

Ordinary car owners are unlikely to be able to identify a breakdown by the problems listed above. Therefore, we will tell you about the more obvious symptoms of a breakdown, so that you can understand in time what is happening to your car and contact us for an air sprung repair at Hammerhead Garage.
