Your trailer truck’s wheel hub unit is an important part of the vehicle. It helps the wheels turn freely, keeping the drive smooth and safe. The wheel hub unit is composed of precision-engineered parts such as bearings, seals, and sensors, each of which needs good care to increase operational efficiency. When selecting replacement parts for the hub, make sure you hire the best truck technician in Winnipeg. With trucks, the bearings, hubs fasteners, etc. all come separate and it’s up to the technician to install it properly. Improper torque and installation will cause failure. Due to the weights, these units are built to carry, all manufacturers of wheel-end parts build them to the best they can with an emphasis on safety.
The wheel speed sensor on the hub bearings controls the anti-lock braking system (ABS) that determines the speed at which the wheel turns and controls the traction. When the ABS doesn’t work properly, especially while turning around bends, the braking system is affected, endangering those in the truck.
In heavy trucks, the wheel bearings carry a huge amount of weight. It is important to lubricate them to keep them in good condition. Make sure the proper amount of lube oil is added in the fill plug and check the service information before servicing. Here’s how you do it:
- Take the plug out
- Stick your finger into the hole and curl it around and down into the differential at your first knuckle.
- If you can touch oil, it’s ok.
- If not, add more oil.
For trailers, there is clear plastic with an “add” and “full” mark. Shine a light on it to see where the level is. If it’s below add, add more. If it’s full, DO NOT overfill it. Overfilling a hubcap causes added pressure in the hub, and can lead to a blown wheel seal, or hub oil leakage through the vent hole in the hubcap plug.
Another technique you can use to check your hub levels is to check for oil splatter on the back of the tires after each trip. This will almost always be a symptom of a leaking wheel seal. If you do notice a leaking wheel seal, bring your truck to an expert truck repair company.
