For the scope of work note the following, in particular:
Before mounting a wheel-and-tire assembly all conduct the following operation steps carefully.
When conducting additional cleaning work using an emery cloth, wire brush, flat scrapers, wheel hub cleaner or thread-cutting tools, only remove the deposited corrosion and dirt layer. There must be no material removal from the component.
Always replace damaged or deformed component parts.
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.
Daimler AG shall not be held liable where disk wheels, wheel spacers and wheel bolts or wheel nuts from other manufacturers are used, in which the wheel connection was not checked and approved by Daimler AG.
Inform customer about this.
Subject to separate repair order: conduct the following activities:
Cleaning the radius seats
More intensive cleaning work using emery cloth, wire brush, wheel hub cleaner, flat scraper or thread-cutting tools
Replacement of components
Do not use bevel gear bolts for mounting MB light-alloy wheels.

Contact surface soiled with grease, not OK |
Contact surface with corrosion products, not OK |
Contact surface cleaned and without deformation, OK |
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. |
Do not use any cleaners containing lubricating agent or greasing agent. |
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 oil, grease and sand, and deposited corrosion. |
If there is any soiling or deposited corrosion, remove it using a wire brush or thread cutter, and clean thread using cleaner. |
Do not use any cleaners containing lubricating agent or greasing agent. |
5 | Check inside thread of wheel hub or thread on wheel stud for damage and deformation. |
If deformation or damage is present, replace affected components. |

Linke Bildhälfte | Contact surface not cleaned, not OK |
Rechte Bildhälfte | Contact surface cleaned and without deformation, OK |
Radius seat not cleaned, not OK |
Radius seat cleaned and without deformation and scoring marks, OK |
6 | Check disk wheel and rim flanges for deformation and damage. |
In event of deformation or damage, replace disk wheel. |
7 | Clean contact surfaces and center hole guide for disk wheel of lubricants and soiling such as, e.g. oil, grease and sand. |
Use cleaner and rag. |
Do not use any cleaners containing lubricating agent or greasing agent. |
8 | Check contact surfaces and center hole guide on disk wheel for deposited corrosion. |
If deposited corrosion is found on the contact surfaces and center hole guide, clean them using a suitable tool (see above). Clean light alloy wheels using flat scraper and rags only. Then repeat operation step 7. |
9 | Check contact surfaces and center alignment on disk wheel for deformation and damage. |
In event of deformation or damage, replace disk wheel. |
10 | Check radius seats of disk wheels for soiling such as, e.g. oil, grease and sand. |
Clean radius seats with soiling using cleaner and rag. |
Do not use any cleaners containing lubricating agent or greasing agent. |
11 | Check radius seats of disk wheels for damage, scoring marks, corrosion, ring shaped material removal in circumferential direction and out-of-roundness. |
If radius seats exhibit damage, scoring marks, corrosion, material removal or out-of-roundness, replace disk wheel. |

12 | Check thread of wheel bolts or wheel nuts for soiling, such as oil, grease and sand, and check for deposited corrosion. |
If there is any deposited corrosion or soiling, remove it using a wire brush or thread cutter, and clean thread using cleaner. |
Do not use any cleaners containing lubricating agent or greasing agent. |
13 | Check radius seats of wheel bolts or wheel nuts for soiling such as, e.g. oil, grease and sand, damage, scoring marks, corrosion, material removal and out-of-roundness. |
Clean radius seats with soiling using cleaner and rag. |
Do not use any cleaners containing lubricating agent or greasing agent. |
Apply corrosion protection
14 | Apply a thin coating of hot lubrication paste as corrosion protection to the marked area of the center hole guide (arrow) on the wheel hub or wheel flange and wheel contact surface. |
Do not apply grease or other lubricants to threads of wheel bolts, wheel nuts, wheel hubs, wheel flanges or wheel studs. |
