Heavy truck differential repair in Laval.

Every heavy-duty truck and trailer relies on a properly functioning differential. A differential is a gearbox composed of three core components: a ring gear, a side gear, and a pinion gear.

Its main function is to distribute power from the engine to the wheel axles while allowing each wheel to rotate at a different speed. This is essential when the vehicle turns, as the inside and outside wheels must travel different distances simultaneously.

The differential also regulates wheel speed to maintain control and stability under load. Without a properly maintained differential, a heavy truck cannot perform reliably or safely on the road.

Any wear, damage, or lubrication failure within the differential can lead to serious mechanical issues. This is why regular inspection, maintenance, and timely repair are critical for any fleet operating under demanding conditions.

Ressorts Laval / C.T. CAM specializes in the repair, diagnosis, rebuilding, and refurbishment of differentials using quality parts for all major heavy-duty and light-duty truck brands.

When choosing a differential repair service, it is important to consider the area where you drive most often. It is crucial to consider the terrain on which the vehicle will be driven. Gravel roads and dirt roads will have an impact on the vehicle’s differential.

Differential maintenance varies from one vehicle to another. Using differential fluid will have a positive impact on the health and safety of the vehicle. When the vehicle’s differential makes noise, it means that the vehicle is not sufficiently lubricated. The average cost of repairing differentials depends on the type of repair.

Sometimes, it’s not just the rear end that needs repairing. Replacing the oil is not a major repair and will not be very expensive. However, if the differential requires more extensive repairs, it will be more costly.

Lubrication is essential to keep the truck’s differential in good condition. Changing the differential on a regular basis is necessary.

If you do not lubricate the differential on a daily basis, the vehicle will not drive as expected. The differential oil must be in good condition. Differential gears can overheat due to friction. Therefore, using differential oil will help prevent equipment wear.

We rebuild differentials using original products as well as parts from qualified suppliers. We rebuild and sell our own reconditioned units, or rebuild customer units when required. We also completely remanufacture differentials from the ground up when the extent of damage requires a full rebuild rather than component-level repair.

Our rebuilt and remanufactured units are guaranteed and cost significantly less than purchasing new ones, making them an ideal solution for fleets looking to control maintenance costs without compromising performance.

The differential should be inspected regularly, even if no visible symptoms are present. Waiting for a breakdown can result in costly repairs and unexpected downtime on the road.

In the transport industry, preventive maintenance is essential to ensure reliability and avoid operational disruptions.

You should consider an inspection:

• As soon as you notice noise or vibration
• When there is a visible oil leak
• After heavy use or overloading
• During routine maintenance intervals

These situations allow potential issues to be detected early. In many cases, simple maintenance such as fluid replacement can prevent major repairs. Checking the differential at the right time helps extend its lifespan and ensures consistent performance.
