While you should conduct pre-and post-trip inspections to catch any issues early, that’s not the only time to be proactive. During long drives, it’s just as important to be aware of what signs or sounds mean there’s something wrong. Of course, not all noises from your semi-truck mean trouble, but knowing which ones do, will save you from serious semi-truck repairs.
Clicking or Clacking at Slow Speeds
While driving at slower speeds, keep an ear out for any clicking or clacking noises, especially from the front tires. Clicking sounds can also happen when turning, and the sound points to different issues.
If it comes from the front tires, it could be a sign of trouble with the drive axles, likely with the u-joint. If there isn’t enough lubrication or it’s worn down, you will start to hear clicking and clacking. When the clicking sounds come from the engine, it could be due to a low engine oil level. In that case, stop and check the levels or schedule some semi-truck services.
Engine Rattling at Acceleration
Does your engine make a loud rattle when you accelerate? If yes, it could be a sign of significant combustion issues. The fuel and air mixture in the engine cylinder is being ignited prematurely before the piston can reach the top stroke. When that happens, and if left unchecked, it can cause damage to the pistons, valves, and connecting rods. Rattling can also be from the engine overheating, trouble with the knock sensor or poor fuel octane. Whatever the root causes, don’t ignore a rattling engine before getting fleet maintenance.
Growling When Driving or Turning
If you hear what sounds like an animal growling from under your hood, the good news is it’s not really an animal. The bad news is it’s a sign of some serious power steering pump failure. The power steering pump ensures fluid reaches the semi-trucks power steering system. Over time, wear and tear can affect the steering pump and cause growling when turning or driving. So when you hear growling, schedule your semi-truck service with a mechanic as soon as possible to avoid accidents or high costs.
Does starting your engine result in a loud squealing noise? When that happens, engine belts are the likely culprit. When the rubber belt slips onto the metal pulley, it creates that loud squealing. Poor tension or an old, cracked or brittle belt can cause the belt to slip. It can also be caused by the engine heat and dirt on the belt. Regularly inspecting the belts is the best way to catch premature wear, but if you hear squealing, get semi-truck repairs immediately.
