Truck Mechanic Tips

Follow the severe-duty maintenance schedule if you tow or haul regularly
Change transfer case and differential fluids every 50,000-60,000 km
Upgrade to heavy-duty brake pads if you tow frequently
Check U-joints for play every time you rotate your tires
Don't ignore DEF or DPF warnings on diesel trucks—they will cause the engine to derate
Have your truck's suspension inspected annually, especially if you carry heavy loads frequently

Frequently Asked Questions

How much does truck brake service cost in Thunder Bay? +
Truck brake pad and rotor replacement for one axle costs $400-$800 due to larger, heavier-duty components compared to passenger cars. Heavy-duty or one-ton trucks may cost more.
How often should I service my 4WD system? +
Transfer case and front/rear differential fluids should be changed every 50,000-60,000 km, or more frequently if you use 4WD regularly or drive through water crossings.
Do lifted trucks need special maintenance? +
Yes, lifted trucks put additional stress on CV joints, driveshaft angles, ball joints, and tie rod ends. They need more frequent alignment checks and steering component inspections.
Is the diesel truck maintenance schedule different from gas? +
Yes, diesel trucks require additional maintenance items including fuel filter changes, DEF system service, DPF regeneration management, and often more expensive oil changes due to higher oil capacity.
