We clean the hinge body and cover from dirt and clamp the drive shaft in a vise with soft metal jaw pads.
We pry off with a screwdriver the retaining ring located in the groove of the shank of the inner hinge housing..
...and take it off.
We bite the large collar of the cover with side cutters..
... or, by inserting a screwdriver blade into the clamp lock, unclench it.
Similarly, we unclench the lock of the small clamp.
We shift the hinge cover along the shaft. With a rag, remove the grease from the end of the hinge cage. We clamp the shank of the inner hinge housing in a vise with soft metal jaw pads.
Using two screwdrivers or special tongs with flat jaws, we unclench the "antennae" of the retaining ring that fixes the hinge cage on the drive shaft.
When performing this operation, it is necessary to center the retaining ring with the tool as accurately as possible relative to the hole of the hinge cage, so that when the ring is unclenched, it is around the entire circumference (except for the "mustache") completely entered the groove of the clip.
An uncentered ring, when the antennae are expanded, will not completely enter the groove of the hinge cage and will not release the drive shaft (for clarity, the drive shaft is removed from the holder).
As soon as the retaining ring enters the groove of the hinge cage and at the same time leaves the groove on the drive shaft, pull the shaft along its axis and remove it from the inner hinge cage.
Remove the dirt cover from the shaft.
If the hinge is removed only to replace the cover, when it is known that it has recently been damaged and the CV joint has retained its performance, then, without disassembling the hinge, we remove the maximum possible amount of lubricant from it and wash it in kerosene. We wipe the hinge with a rag and blow it with compressed air. We inspect the balls, the separator, the clip and the internal cavity of the body. Seizures, dents, cracks, traces of corrosion are not allowed - we replace such a hinge.
We clean the shaft of old grease and apply a thin layer of new grease to it. We put a hinge cover on the shaft.
We install a new retaining ring in the hinge cage and put new grease into the cavities of the hinge body and cover, a total of 120–140 g.
We put the hinge on the shaft, ensuring the fixation of the retaining ring in the groove of the shaft.
We check the mobility of the hinge - it should move without jamming. We pull the cover onto the hinge body so that the belts of the cover for the clamps are located in the corresponding seats of the shaft and the hinge body. We fix the hinge cover with new clamps.
We install a new retaining ring in the groove of the shank of the inner hinge housing.
