Dust cover of the joints speed

In order to prevent the disruption of the dust cap of the constant velocity joints it is necessary to conduct visual inspection of the condition of the CV dust coupling. We recommend replacing the dust cover with the appearance of a crack, before it is completely destroyed. It happens more often with older cars because of aging and hardening of the rubber and the appearance of cracks. But if the dust cover is still torn, it needs to be replaced.

Stuck coupling

Corrosion, stuck, burned and rusted joints are always a problem, especially in cars with significant performance. The products of oxidation reaction are capable of multiplying by volume. As a result, the joints are tight. In addition, contaminants and fine mud entering the joint often increase the friction between the mating components.

To solve this problem, you should use high penetration agents, which can significantly reduce friction and dissolve contaminants.

Wheel hub bearing

If the noise generated by the wheel hub has occurred recently, it can be removed with the help of XADO repair grease. The high concentration of Revitalizant® in this fat eliminates significant accumulation wear in friction pairs.

The steering wheel "howling", the unwanted sound in the difference

Main reasons:

1) Low oil level

  • Gland seal of the pinion gear is damaged.
  • Gland seal of the half axles are damaged.
  • Breather is contaminated or damaged.
  • Loose fitting clog of the filler opening or drain hole.
  • Differential cover leaks.
  • Damage of the sealing gaskets.

2) Contaminated transmission oil

  • Oil contains big amount of moisture and (or) contaminations.

3) Transfer gear box or differential are broken.

  • Big clearance in bearings of the pinion gear.
  • Improper adjustment or wear of gears.
  • Stiff rotation of spider pinion on the axle.
  • Scratches on the operating surface of the spider pin.
  • Sticking of gears or half axles in the differential compensating case.
  • Improper clearance between gear teeth of the differential.

4) Wear of the half axle bearings.

5) Wear of the spline joint with side gears.

6) Half axles are misshaped or have inappropriate jumping.

7) Loosening of crankcase hold-down bolts of axle gearbox, unfastening of pinion nut, ring gear or swash.
