The wheel hub bearing howls
If noise from wheel hub bearing operation has appeared relatively recently, it can be eliminated by using XADO Repair Lubricant. A high content of Revitalizant® in this lubricant allows to eliminate significant accumulated wear in friction couples.
Application Notes
Dismantle the assembly, clean the bearing from the old lubricant and rinse. During the visual inspection make sure that there are no significant scratches more than 0.1 mm deep, damage and holes on the bearing raceways. The bearing cage should be undamaged. Then fill the bearing with the XADO repair lubricant. During storage filling, no more than 2/3 of the free interior space is to be filled. Reassemble and adjust the assembly. The noise of the bearing should be reduced after 2,000-3,000 km of mileage.
Application Notes
After 8,000-10,000 km of mileage with XADO repair lubricant and complete elimination of the defect, it is recommended to replace the old lubricant in the bearing with XADO lubricant for constant velocity joints.
Hints
After 8,000-10,000 km of mileage with XADO repair lubricant and complete elimination of the defect, it is recommended to change the lubricant in the bearing to XADO lubricant for constant velocity joints.
