- 📏 Accurate measurement and adjustment of bearings to achieve a range of one to five thousands to prevent ABS light activation.
- 🔨 Bendable stars should be bent a minimum of two on the flat, not on the points, for proper engagement and function.
- 💡 Lubrication is key for all moving parts including the inner and outer bearings, seal installation, and to prevent contamination during reassembly.
Q & A
What is the first step in the inspection process for a wheel end?
-The first step in the inspection process is a visual inspection, where you walk around the wheel to check for any oil or leakage on the outside of the hubcap, hub, or wheel.
What are some common problems that can be identified during the visual inspection of a wheel end?
-Common problems include a leaky gasket on the hubcap, cracks or a broken window in the hubcap, and overfilling the wheel end with too much lubricant causing misting.
What is the recommended action if a hubcap has a crack or broken window?
-If a hubcap has a crack or broken window, it needs to be replaced to prevent further issues.
How can overfilling a wheel end with lubricant cause a problem?
-Overfilling a wheel end can cause misting, where the excess lubricant blows out through the center of the red plug, leading to oil getting on the hubcap, hub, and wheel.
What is the purpose of the pro torque nut and its keeper in the Stamkos system?
-The pro torque nut ensures the correct torque is applied to the wheel end, and its keeper, which may have tear drops or paddles, allows for easy removal of the nut without tools on steers.
What should be done when replacing a wheel seal?
-When replacing a wheel seal, it's important to clean the spindle surface, use the correct driver, and install the seal dry. Also, ensure the seal turns freely during installation.
How do you determine if a bearing is bad during inspection?
-If there is pitting on the rollers, staining indicating the equipment has been in water, or discoloration from overheating, the bearing should be replaced.
What is the correct procedure for cleaning bearings and hubs?
-Bearings and hubs should be cleaned using a parts washer with non-flammable solvent. After cleaning, they should be wiped dry with a lint-free towel and not exposed to steam or water to prevent rusting.
What is the recommended torque for the outer nut on a two and five-eighths spindle?
-The recommended torque for the outer nut on a two and five-eighths spindle is 300 foot-pounds.
How do you adjust the bearings according to the TMC SRP 618 procedure?
-According to the TMC SRP 618 procedure, you initially torque the bearings to 200 foot-pounds while rotating the wheel, then back it off one full turn. The final torque is 50 foot-pounds while rotating the hub, and for a trailer application, the nut should be backed off a quarter turn.
Why is it important to keep the bearing adjustment within one to five thousands of an inch?
-Keeping the bearing adjustment within one to five thousands of an inch is crucial to prevent the ABS light from coming on and to ensure the longevity and proper functioning of the wheel end.

Highlights
The process begins with a comprehensive inspection of the wheel, including looking for oil leaks or leakage on the outside of the hubcap.
A leaky gasket on the hubcap is a common issue that can be easily fixed.
A cracked or broken hubcap should be replaced to prevent further damage.
Overfilling the wheel with lubricant can lead to misting, where the oil is forced out through the center of the red plug.
The sight glass on the hub cap indicates how much lubricant should be added, and the plug should be replaced when it becomes hard and pink.
Gaskets should always be replaced with new ones, and silicone should not be used as it can hinder the performance of the bearings.
The Stamkos pro torque nut has a redesigned keeper that can be removed with bare hands, making the process more user-friendly.
On conventional wheels, nuts should be removable by hand, and if not, it indicates that the wheel ends have been over-tightened.
The Guardian seal with a deflector ring is introduced, which should be replaced with a Voyager seal before reassembly.
Deflector rings should be removed carefully without using chisels or porches to avoid damaging the spindle.
The wheel seal should be removed using a heal bar and crow's foot, and the bearings should be cleaned thoroughly.
Inspect the bearings for pitting, staining, or discoloration, and replace them if they show signs of damage or wear.
The hub should be cleaned with a parts washer and a lint-free towel, ensuring that no grit or moisture remains.
When replacing the race or the cup, use a cup driver and mild steel drift to avoid damaging the components.
Lubricate the bearings and clean the threads and keyway before reassembly to prevent contamination and ensure smooth operation.
The Voyager seal is a hub install seal with wide coverage, and it should be installed following the instructions on the box.
Use the correct driver for installing the seal and ensure that the seal turns freely during installation.
Tighten the double nuts and adjust the bearings according to the TMC SRP 618 procedure for legal compliance and optimal performance.
Ensure that the dowel washer lines up with the pin for proper assembly, and adjust the bendable stars for a secure fit.
