Frequently Asked Questions About AD Truck Service
AD Truck Service provides diesel repair, commercial vehicle maintenance, inspections, trailer service, fleet maintenance and roadside assistance in Fairview and throughout the greater Portland area, surrounding Oregon communities and Southwest Washington. Our technicians work on semi trucks, buses, RVs, motorhomes, trailers and other commercial vehicles. Below are answers to common questions about our services.
Where are you located?
We're at 23012 Northeast Sandy Boulevard, Fairview, OR 97024 — serving Oregon and Southwest Washington, including on-site fleet visits for qualifying accounts.
What are your hours?
Monday–Thursday, 6:30 a.m.–6:00 p.m.; Friday, 6:30 a.m.–3:00 p.m.
Do you work on semi trucks and heavy-duty diesel trucks?
Yes — we specialize in commercial trucks (Class 5+) and handle nearly everything short of a full engine rebuild: diagnostics, component repair, transmissions, brakes, and suspension, on tractors, straight trucks, and trailers.
What diesel-specific services do you offer?
Diesel diagnostics, turbo service, cooling system repair, and DPF filter cleaning (Enviromotive equipment, Cummins-backed, all makes/models Class 5+, $250–$350 per filter) and forced regeneration ($200). We do not perform full engine overhauls or rebuilds.
Do you service buses and RVs?
We offer limited service for buses and RVs — oil changes, inspection checks, and brake work. For anything beyond that, our full range of services is focused on commercial trucks.
Can you rebuild or replace transmissions and clutches?
We don't rebuild or repair transmissions in-house, but we do full transmission replacements, clutch and actuator replacement, and transmission diagnostics.
Do you handle brake and suspension repair?
Yes, for trucks and trailers, including drive-axle spindle repair.
Do you offer tire service?
Yes — new tire installation, flat repair (patch/plug, $60), and full truck/trailer alignments. Standard labor is $135/hour, with alignments running about 3 hours for a truck and 2 hours for a trailer.
Do you offer preventive maintenance (PM) service?
Yes — our standard PM service (oil change, inspection, and greasing) is a flat $150 in labor plus parts (oil, filters, and fuel water separator as needed).
Do you do DOT inspections?
Yes — our DOT Annual Inspection is $100 for a truck and $50 for a trailer.
Do you do CARB testing?
Yes, California CARB testing is available for $200.
Do you repair trailers?
Yes — brakes, suspension, electrical systems, and lighting.
Do you offer special rates or discounts for fleets or regular customers?
Yes — we offer special pricing for qualifying fleet accounts and regular customers, with a dedicated point of contact for fast estimates and scheduling. We work best with fleet operators running roughly 10–500 trucks, and many of our fleet accounts manage everything (approvals, questions, invoicing) directly with us rather than through individual drivers. Reach out, and we'll talk through what fits your account.
Do you offer roadside assistance or mobile repair?
Yes. Roadside labor is $175/hour with a $100/hour drive-time charge (1-hour minimum), plus a service call-out fee of $60 within 30 miles or $150 beyond that, and a $0.65/mile fuel surcharge. Battery jump-starts within 30 miles are a flat $150.
