REPAIR MATERIALS
Before mounting a wheel-and-tire assembly all the following operation steps must be carefully conducted.
When conducting additional cleaning work using emery cloth, wire brush, flat scraper, wheel hub cleaner or thread-cutting tools only the deposited corrosion and dirt layer may be removed. There must be no material removal from the component.
Damaged or deformed components must always be replaced. Any residue deposits of corrosion, contamination, material removal from components or damaged components prevent the necessary preload force being reached on the wheel bolts or wheel nuts, despite reaching the specified torque!
Otherwise the wheel-and-tire assembly may work its way loose from the vehicle thereby causing damage! When using disk wheels, wheel spacers and wheel bolts or wheel nuts from other manufacturers, in which the wheel connection was not checked and approved by Daimler AG, Daimler AG shall then not be held liable.
Notify the customer about this accordingly.

1. Clean contact surface on wheel hub, wheel flange, brake disk or brake drum, center hole guide and joints for lubricants and soiling such as, e.g. oil, grease and sand.
Use cleaner and rag.
2. Check contact surface on wheel hub, wheel flange, brake disk or brake drum, center hole guide and joints for deposited corrosion.
If deposited corrosion is present, remove it using a wire brush or emery cloth or wheel hub cleaner, and then repeat operation step 1.
3. Check contact surface on wheel hub, wheel flange, brake disk or brake drum, center hole guide and joints for damage and deformation.
If deformation or damage is present, replace affected components.
4. Check inside thread in wheel hub or wheel stud for soiling such as, e.g. oil, grease and sand and deposited corrosion.
In the event of any soiling or deposited corrosion, remove it using a wire brush or thread cutter, and clean thread using cleaner.
5. Check inside thread in wheel hub or thread on wheel stud for signs of damage and deformation. If deformation or damage is present, replace affected components.
