Your truck’s differential doesn’t usually fail quietly. It may start with a light humming noise, or a bit of vibration under the seat, but it doesn’t stay that way for long. Ignoring that for a while might end up to dealing with serious driveline damage or even a break down on the highway! A worn or damaged differential can affect traction, fuel efficiency, tire wear, and in worst cases sideline a revenue-producing truck for days.
At Axle Spindle, we provide professional truck differential repairs all around the GTA and southern Ontario. Our team offers fast, reliable onsite and mobile truck differential repair services, handling everything from minor leaks to full heavy duty truck differential repairs to make sure your vehicle isn’t stuck in the yard when it should be on the highway.
Whether you operate a single vehicle or manage an entire fleet, we will handle your differential repair needs with accurate diagnostics and transparent quotes.
Our Truck differential repair services
Diagnostic Checks
Our technicians take a close look at your differentials to identify any issues such as gear wear, bearing failures, and fluid contamination. Early detection always helps prevent costly repairs and extends the lifespan of your differential.
Full Differential Repairs & Rebuilds
We offer expert repairs and complete rebuilds of differentials, addressing different problems like worn gears, damaged bearings, and seal failures. Our goal is to stop small issues from turning into major downtime.
Fluid Replacement
Regular differential fluid changes are vital for reducing friction and preventing overheating. We use high-quality lubricants to ensure optimal performance and longevity of your differential components.
Axle & Seal Repair
Leaking seals and damaged axles can compromise your differential’s integrity. Our team replaces faulty seals and repairs axles to prevent fluid loss and contamination.

Vehicles We Service
Signs of Differential Problems in Trucks
Whining or Howling While Driving
Unusual noises during acceleration or deceleration may suggest worn gears or inadequate lubrication.
Vibration or Rumbling at Higher Speeds
Excessive vibrations can indicate imbalanced components or failing bearings within the differential.
Clunking During Acceleration or Braking
Sudden clunks or jerks might be due to excessive play or damage in your differential gears or couplings.
Leaks Around the Differential Housing
Puddles or drips under your truck could signal leaking differential fluid, which can lead to fluid loss and major internal wear if ignored.
Hard or Unusual Turning
Difficulty in turning or a noticeable resistance may point to differential malfunction or gear issues.
Burning Gear Oil Smell
A strong odor of burning oil suggests overheating, often caused by low or contaminated differential fluid.
Dashboard Traction Warnings
If your traction control or drivetrain light stays on, your vehicle might be compensating for differential slip or gear imbalance.

How Our truck differential repair process work
Inspection and fault confirmation
Our certified technicians verify the noise, vibration, or traction issue, then carefully inspect the driveline, U‑joints, and tires so the problem isn’t misdiagnosed.
Disassembly and measurement
The differential cover is removed, oil is inspected, then gears, bearings, and shims are measured to see what exactly can be reused and what must be replaced.
Repair or rebuild
Depending on the damage, we can performs a partial repair (for example, bearings and seals only) or a complete differential rebuild with new ring and pinion, carrier, and related hardware.
Setup and testing
Gear contact pattern, preload, and backlash are set with the proper tools, then we road test your truck to ensure quiet operation and smooth engagement under load.

How Much Does Truck Differential Repair Cost in Ontario?
The truck differential repair cost for a commercial vehicle can vary quite a bit, and not just by shop, but by what is actually wrong inside the housing. A minor repair where a bearing or seal is replaced will be on the lower end, while a full truck differential repair with new gears, bearings, and setup time is a larger investment.
For an accurate estimate, Axle Spindle typically recommends a quick inspection and diagnostic so we can quote your specific repair rather than giving a guess that may not match the real job.
