Frequently Asked Questions About Trucks Repairs

How often should I change the fuel filters on a diesel truck?

Most manufacturers recommend changing fuel filters every 15,000 to 25,000 miles. However, if you operate in dusty or dirty environments, more frequent replacement can prevent clogging and performance issues.

Why does my truck have low oil pressure?

Low oil pressure may be due to worn bearings, a clogged oil pickup tube, or a failing oil pump. Running the engine with low pressure can lead to serious damage.

How often should I inspect wheel bearings?

Wheel bearings should be inspected at every brake service or roughly every 50,000 miles. Catching early wear prevents breakdowns and keeps the wheel assembly safe.

How do I know if my truck has an electrical issue?

Look for dim lights, slow cranking, or intermittent failures of accessories. These symptoms may signal problems with the alternator, wiring, or battery connections.

When should I flush my truck’s cooling system?

Flush the cooling system every 2 to 3 years or as recommended by the manufacturer. Dirty coolant can cause overheating and corrosion in the radiator and engine.

Omg these guys are great!!! Our starter went out on our box truck at a AMAZON location and this company sent techs out immediately. We are from Richmond so getting back home was crucial and in a timely manner. Antwaun was really professional and I now have him locked in in case of emergencies in the tidewater area.PS they are very affordable compared to other other shops we googled. And definitely more professional.Thank you guys again.

Top Notch Commercial Service did roof work on our Class C RV. Antwan and Jason were wonderful to work with. They kept us updated on the repairs and always gave honest estimates of the cost. Their shop was easy to find, and our RV was safely stored inside their garage while it was being repaired. When they finished the roof work, they offered for us to climb up and view their work. Very friendly staff, professional mechanics. Highly recommended.

Top Notch Mechanical Repair is an absolute lifesaver for fleet managers! I am incredibly thankful they handle federal inspections for our fleet of semi-trucks. Their location in Norfolk is perfect, being just minutes away from the Virginia ports. It makes routine compliance and drop-offs completely seamless. High-quality work and unbeatable convenience!

I cannot recommend Top Notch Commercial Service enough! I had a brake issue that left me completely stranded, and they completely saved the day. I absolutely love that they have their own towing service—it took so much stress out of a terrifying situation. The customer service was absolutely top-notch from start to finish. They got my truck towed quickly, diagnosed the problem, and had me back on the road safely in no time. Fast, honest, and reliable. Thank you to the whole team for taking such great care of me!

As a female owner-operator, I am incredibly thankful for Top Notch Commercial Repair here in Norfolk. It can be hard to find a truck repair shop that doesn't try to take advantage of you, but they truly prioritize good workmanship while keeping costs low. The staff has always been completely spot-on. I personally hope they expand soon so they can handle even more of my business!
