Since 1988 on cars cardan transfer with hinges of the increased durability is established. It externally differs in the increased thickness of forks on an installation site of needle bearings, lack of metal holders under epiploons of a crosspiece and sharper transition of a pipe of the forward driveshaft in shlitsevy a tip (approximately at an angle 90 °). Cardan hinges have the improved consolidation of needle bearings. It is reached by application of epiploons of radial and face consolidation. Cases of needle bearings are stamped from sheet steel, unlike fine-molded of prutkovy steel in earlier applied cardan transfer.
The new and earlier released crosspieces of cardan hinges are interchanged. But it is undesirable to establish crosspieces of VAZ-2105, 2107 in forks of VAZ-2101 driveshafts as in these forks rigidity of stamped cases of needle bearings decreases.
Due to the change of the sizes of forks of cardan hinges the technology of razboro-assembly operation of new cardan hinges is changed. Therefore in the text the technology of repair of both old, and new hinges is described.
