INFOID:0000000005148939
Observe the following precautions when disassembling and servicing the wheel hub and drive shafts.
• Perform work in a location which is as dust-free as possible.
• Before disassembling and servicing, clean the outside of parts.
• Prevention of the entry of foreign objects must be taken into account during disassembly of the component
parts.
• Disassembled parts must be carefully reassembled in the correct order. If work is interrupted, a clean cover
must be placed over parts.
• Paper shop cloths must be used. Fabric shop cloths must not be used because of the danger of lint adhering
to parts.
• Disassembled parts (except for rubber parts) should be cleaned with a suitable solvent which shall be
removed by blowing with air or wiping with paper shop cloths.
