There are several ways, but the most effective is to think back to the last few days of use and consider what kind of faults it is exhibiting. There are several aspects to assess, so here are some of them:
- When using the car, pay attention to the sounds that the acceleration produces. If you find that there are sounds like small grinding noises coming from the compressor, or something that wasn't there the first time you drove it, there is probably a suspension problem.
- With someone else's help, start the car and look at the compressor activation, as well as how long it can stay on. If the compressor is working properly, all is well, but if it is unstable or just won't come on, there is a problem with the compressor relay.
- Check the stability and height of the vehicle at all four corners. Usually they should all be fully balanced, but if there is one that is lower than another or perhaps one part of the car lifts more than another, there is a general problem. In case it is the second option, the most advisable thing to do in that situation is a leak test. So, if our vehicle seems to have a lower altitude, the problem of the compressor and its ends.
- If the sound of the compressor running comes to you when you are driving or just the car is running, it is another sign that there is a possible leak and the compressor is prone to damage.
- Another way to determine if there is a problem is to look at the driving quality of the person behind the wheel. Depending on the route and the car, the car should be stable. But if you are on smooth tarmac and still feel that the vehicle is unbalanced or the cabin is too low, it could be due to a problem with the air springs. The best thing to do is to check them for leaks or cracks. Also consider the time factor, as the air springs begin to age and wear out, they will begin to yield to the weight of the vehicle
How do you find a leak?
This is easy and can be done with simple products that we have at home without having to get very dirty. To do this we will need two tablespoons of liquid soap diluted in a bottle with a little water. After putting these two ingredients together, we will spray the air bag, the fittings, the airlines and the compressor area. At a glance you will see if bubbles are coming out of somewhere or not, if they are coming out, it is definitely a leak. Even so, if there are no bubbles, we cannot totally rule out that there is no leak.
What will change in a remanufactured prop assembly?
New parts containing fittings such as rubber bellows, buffers, bumpers and crimp rings in perfect condition. In the case of shock absorbers, they are used to test products for damage.
