5 Signs Your Truck Needs Immediate Repair 

1. Exhaust Smoke

Unusual smoke from the exhaust is a serious red flag.

• Blue smoke may indicate burning oil

• White smoke can suggest cooling system issues

• Black smoke often points to fuel system problems
  Any of these require prompt diagnostics.

2. Strange Noises

Grinding, knocking, whining, or “metal-on-metal” sounds could signal issues with brakes, suspension, bearings, or drivetrain components. The earlier you address them — the cheaper the repair.

3. Vibration While Driving

Unusual vibration often points to issues with wheel alignment, suspension, or driveshaft imbalance. This is especially dangerous for box trucks on long hauls.

4. Fluid Leaks

Whether it’s oil, coolant, brake fluid, or fuel — leaks are never “normal.” Even a small drip under your truck could lead to serious breakdowns or safety risks.

5. Overheating

If your dashboard shows high engine temperature or your hood feels too hot — don’t delay. Overheating can be caused by coolant leaks, thermostat failure, or a damaged head gasket.

Pro Tip from Pro Technical Service:

Don’t ignore “minor” symptoms — a quick visit today can save thousands tomorrow.
