Please read the ConMet Service Manual for Steer, Drive, and Trailer Hub Assemblies. It details the recommended maintenance and service for all ConMet wheel ends, including pre-trip inspections, post-trip inspections, and preventative maintenance. 

For ConMet wheel ends, refer to the Lubrication chapter of the ConMet Service Manual for Steer, Drive, and Trailer Hub Assemblies. Oil fill volumes for steer and trailer assemblies are dependent on hubcap and spindle dimensions and are shown on the hubcap sight window. For non-ConMet wheel ends, consult your trailer or tractor OEM. 

All ConMet hub warranties can be located by hub type on our Resources page.

Yes. PreSet and PreSet Plus hubs are fully serviceable and rebuildable. We also strongly recommend assessing the benefits of replacing the entire hub when service is required. View the reasons why you should replace your hub on our Aftermarket page.

Please use the ConMet App online or download the app to easily find the correct replacement ConMet products (North America specific) or please call your local Customer Service representative as found on our Contact Us page.

Some drag is normal for a new seal, but excessive drag or roughness may indicate excessive bearing preload which could result in premature seal failure. An incorrect combination of parts or the use of one or more non-PreSet parts may cause this condition. Please refer to the installation and service instructions in the ConMet Service Manual for Steer, Drive, and Trailer Hub Assemblies.

It is also possible that a build-up of rust or debris on the spindle, specifically on the seal journal, is causing excessive seal drag. Detailed instructions on how to prepare and clean the spindle before seal and hub installation can also be found in the ConMet Service Manual.

The PreSet spacer is a critical component to the hub design and is needed for PreSet technology to function. The spacer is required to properly space the bearings of a PreSet hub. It is clamped between the two bearing cones with a high spindle nut torque. Using a PreSet or PreSet Plus hub without a PreSet bearing spacer will also render the warranty invalid. Visit the PreSet Plus page for more detailed information about the spacer and PreSet technology.

For best performance, ConMet recommends the use of the PreSet Plus spindle nut. However, PreSet hubs do accommodate one-piece spindle nut systems and double nut (jam) systems. ConMet does not recommend a one-piece “castellated” type nut system for use with PreSet hubs. For instructions on proper spindle nut installation, please refer to the ConMet Service Manual for Steer, Drive, and Trailer Hub Assemblies.

Yes, according to the ConMet Service Manual for Steer, Drive, and Trailer Hub Assemblies you may convert a hub, but you need to be very vigilant about stud length, drum pilot diameter, and the cap nuts used. For specific instructions and further details, please refer to the Brake and Wheel Installation chapter in the Service Manual.

Not necessarily. There are some other manufacturers that make or have made aluminum hubs. Check for a ConMet logo cast into the hub, or verify the part numbers stamped or cast into the hub using the ConMet App or by reaching out to your local Customer Service representative on our Contact Us page.

No. ConMet PreSet rebuild kits and PreSet Plus spindle nuts should only be used with ConMet PreSet hubs. Only ConMet PreSet hubs are designed to utilize these components and function properly. Use of the kit components or spindle nut in hubs other than ConMet PreSet or PreSet Plus could result in wheel end failure and/or vehicle damage.

Detailed instructions and tips for removal can be found in the ConMet Service Manual for Steer, Drive, and Trailer Hub Assemblies and also the Service Bulletin entitled “Removing Frozen Hubs from the Spindle.”
Aside from outside contamination, this is normal fretting corrosion and is related to the small movements of the bearing against the spindle in service. The effect of fretting can be greatly reduced by applying a coating of grade 2 grease to the spindle bearing journals before installing the hub. In severe cases, the bearing cones will adhere to the spindle and require a special tool to remove the hub.
The spindle can be reconditioned with emery cloth or a fine sand paper to remove the excess rust before installing the hub. Consult your tractor or trailer OEM, or the axle manufacturer in cases of severe spindle damage.

Yes. Single wheels impose different loading conditions on the hub, bearings, and axles when compared to dual wheels. As a result, the hub load ratings change according to wheel offset. For detailed information, please refer to the Technology Bulletin on “Wheel End Load Ratings for Hubs Used in Single Wheel Applications.”

TruckWings automatically deploy at highway speed to close the gap between tractor and trailer, causing air speed to drop and reduce downstream turbulence. An increase in back-of-cab pressure reduces overall drag on the tractor-trailer – especially in high crosswind environments, resulting in an improvement in fuel efficiency and a decrease in carbon emissions.

No, TruckWings are fully automated in deployment and retraction – zero action from the driver is necessary to realize fuel savings on every trip.

The TruckWings controller installed on the truck CAN data link provides real-time speed information to determine if the truck is at highway speeds and safe to deploy. A smart distance sensor scans the area behind TruckWings to ensure adequate clearance exists to deploy safely.

ConMet TruckWings provides performance reports and operational uptime monitoring pulled directly from the truck, sent to the cloud, and delivered to the fleet for review and analysis.

The majority of class 8 tractors with full aerodynamic fairing packages and horizontal exhausts from Kenworth, Freightliner, International, Volvo, Peterbilt and Mack are supported.

The panels are made from glass-reinforced polypropylene. This material is widely used in the industry inside trailer bodies and other aerodynamic technologies due to its light weight and durability. The frame is made of 5052 aerospace-grade aluminum that is fastened together using Grade 8 corrosion-resistant bolts. It is fastened to the back of the cab with high-strength aluminum rivets used in shipbuilding, trucks and passenger buses, and trailers.

The average system weight is 240 lbs.

TruckWings are powered using the truck’s own secondary compressed air system to drive three pneumatic cylinders controlled by a central directional valve.

TruckWings have been road-tested by fleets over 700 million miles across Canada and the United States in multiple winters of snow, wind, and ice. We apply the same corrosion-resistant zinc-aluminum plating used in truck undercarriages on all fasteners. The ISO 15552 rated actuators are capable of performing to -30ºF and resist all wind loads within the safe operating limits of the tractor. They have undergone 10-year accelerated life testing to ensure operation over the life of the product.

TruckWings can be shipped fully assembled – only requiring adapter brackets to be riveted to the cab before lifting the entire system onto the brackets. The total install by the modification center or dealership typically takes less than two hours from start to finish.
