Auto Repairs and Servicing

Hello, my name is Walter. Over the past few months, I have been working on my car. I never used to think much about my car. I would just jump into it and hit the road. Things were fine at first, but soon I realised that things were starting to go wrong. Strange white smoke started to appear from the exhaust. Sometimes when I changed gear, I could hear a strange noise. Foolishly, I ignored all of this until my car broke down. When I got to the auto repair shop the mechanic repaired my car and then gave it a full service. As he did so, I began my auto servicing education.

What Are The Vulnerable Parts Of A Truck Air Suspension System?

by Margie White

Almost all heavy-duty trucks these days feature an air suspension system. It's remarkably resilient and can put up with a tremendous amount of wear and tear, but issues can arise as with anything else mechanical. What are some of the typical challenges in this area, and if you operate one of these vehicles, how can you avoid running into them?

How The System Works

Firstly, it's important to understand how an air suspension system works. On each corner of the vehicle will be a heavy-duty rubber airbag that is designed to hold just the right amount of air for perfect operation. The air will be supplied through a compressor system, which brings in air from the surrounding atmosphere and puts it under pressure. However, it will first need to go through a dryer mechanism because air contains a certain amount of moisture, and this needs to be removed so that it does not cause corrosion and other problems within the system.

Once the system is primed with this compressed air, it is pumped to each corner of the vehicle in very precise amounts based on sensor mechanisms. These sensors detect the position of the airbag in relation to the corner of the vehicle it is meant to support and make fine adjustments as needed. This will help to ensure a smooth and safe ride in normal circumstances.

Air Leaks

Occasionally, the system can develop a leak and allow air to escape. This could happen to some of the rubber seals, which are more susceptible to damage or deterioration, but many individual components of the system can contribute to this problem. An airbag can also puncture, and should this happen, the vehicle will sag to one side.

Compressor Malfunction

Occasionally, the compressor can malfunction. You may notice that it runs continuously or not at all, and in the latter case, you won't be able to drive the vehicle.

Other Components

In addition to the more mechanical parts, there are some electronic items to consider. These help regulate the flow of air, opening and closing the valves as needed.

Over To The Experts

To try and avoid any problems, you should always service your truck's suspension as recommended by the manufacturer and in accordance with industry standards. If you do so, the mechanic will have a close look at the system and be able to spot any deterioration before it develops any further.
