You should disassemble the unit following the cleaning and flushing of the bearing. Check if there are any severe scratches, chips or holes deeper than 0.1 mm on the operating surfaces of the bearing. Make sure that the bearing cage is not damaged. Then apply XADO Repairing grease by filling the bearing not less than 2/3 of the free inner volume. The unwanted sounds will be reduced after 1,200 – 1,800 miles of run.


After restoring of the defects with a help of the XADO Repairing grease, it is advised to change the grease with XADO Grease for constant velocity joints.
