J&J Automotive Truck Repair

Diesel truck & fleet repair in Bay Shore

J & J Automotive-Truck Repair works on diesel and commercial trucks and provides fleet maintenance from its seven-bay shop at 321 Orinoco Drive in Bay Shore. Whether one work vehicle needs attention or several units are due for service, start with the vehicle details and the problem. Jeff and the team can discuss repair needs, availability and the next step.

Commercial truck repair and diesel service

Truck repairs are part of the shop’s core work. A brake concern, hard start and running fault each need different information. Describe the symptoms, recent repairs and any fault messages so the team understands why the truck is coming in.

  • Diesel engine diagnostics and repair
  • Engine, transmission, driveshaft and drivetrain work
  • Commercial truck brakes, steering and suspension
  • Electrical and starting-system concerns
  • Cooling systems, belts, hoses, mufflers and exhaust
  • Oil, filters, fluids and preventive maintenance

Plan maintenance for the vehicles your business uses

Send the vehicle types, unit identifiers, mileage and maintenance records you have. Identify the person who will discuss the work and any scheduling constraints. A maintenance request gives the shop the information to coordinate with you; it does not automatically establish a fleet contract, account terms or reserved capacity.

Shop service or mobile truck repair

Bring vehicles to the Bay Shore shop by arrangement. Truck broke down somewhere else? Call (631) 919-0157 and we'll get you sorted. Larger repairs may need shop equipment.

Truck and fleet service questions

Can I bring in just one work truck?

Yes, one truck or a whole fleet. Tell us about your fleet and we'll collect your preferred times for Jeff.

Do you offer a guaranteed turnaround for fleet vehicles?

Timing depends on what we find, the parts and the job. Tell us about your fleet and we'll collect your preferred times for Jeff.

Can mobile service replace a shop visit?

That depends on the location, vehicle and repair. Call with the details. The team can discuss on-site options, but some work requires bringing the vehicle to the Bay Shore shop.

What should a fleet manager include in a request?

Vehicle and engine details, unit number, mileage, symptoms, service history and a repair contact are useful. Identify which units are out of service and any preferred timing. Account terms and recurring maintenance arrangements are agreed directly with the shop.
