The Most Common Problems With Commercial Trucks And Getting The Right Parts To Fix Them
Posted on: 28 January 2022
The owner of a commercial truck knows how important it is that they get the right parts for their truck. It's not just about the cost of the parts. It's also about obtaining high-quality parts and getting them quickly so your commercial truck can be on the road again. The following issues are some of the most common problems with commercial trucks and truck parts that can help you deal with these issues.
Gear Failures of Transmissions and Rearends
A broken gear in the transmission or rear axle can be the most expensive repair a driver will ever have to deal with. Truck drivers who routinely travel long distances should be able to spot early warning signs of potential problems. These indicators include:
- Grinding noises – If a truck driver hears grinding noises when he shifts gears, then this could be the first sign that there are transmission issues that need to be repaired.
- Sudden shifting – If one of the gears in a truck driver's transmission begins to shift suddenly without warning, then this could be a sign that something is wrong with the truck's transmission.
- Noisy shifting – When a truck driver hears grinding or clicking noises while shifting gears, then these sounds might indicate a problem with his transmission.
- Hesitation – Hesitation while accelerating can be caused by a transmission problem as well as other mechanical issues such as a bad fuel pump or ignition coil.
- Transmission fluid leaking – If a truck driver notices that its transmission fluid levels have dropped significantly, then there could be an issue that needs to be repaired.
These are common issues with transmissions, but they could also be due to a problem with the rear end of commercial vehicles.
Issues with Diesel Engines
A common issue with diesel engines is the fuel injection pump. Fuel pumps are responsible for injecting the proper amount of fuel into the engine. Sometimes, they just stop working. When this happens, you can't start your truck.
Troubleshooting a faulty fuel injection pump is easy. Most fuel injection pumps have an indicator light that will turn on when there's a problem. If it doesn't, you'll need to use a voltmeter to check if the pump is getting power or not. A bad ground connection can also cause problems with your fuel injection pump, so check that first and make sure that all connections are tight and secure.
Another common problem with diesel engines is the glow plug control module (GPCM). This module controls the glow plugs that heat up before starting the engine. The GPCM sends power to each glow plugin sequence until it reaches the right temperature because diesel needs heat to provide combustion to the engine. If your truck doesn't start, it may be because of faulty GPCM or glow plugs. It could also be other issues like a bad fuel pump or filter that causes issues when starting your engine.
