INTRODUCTION
FIXED RZEPPA JOINT
Rzeppa joints are built with outer race, inner race,
cage and six balls. Outer race and inner race have
spherical ball grooves. Cage is assembled first with
inner race / six balls and then outer race is assem-
bled. Torque is transferred from inner race to outer
race through six balls.
PLUNGING DOUBLE OFFSET (DOJ) JOINT
DOJ is similar to Rzeppa joint, except for outer race
which has straight and longer ball grooves, instead
of spherical grooves as in case of Rzeppa joint. Inner
race and cage can slide in and out on six balls to
compensate change in length of CV shafts.
Constant velocity joints used on both RH side and
LH side are same, but for the difference in male and
female splines at DOJ end.
LH half shaft has male splines on DOJ side and it fits
in side gear in differential case.
RH half shaft has female splines and it fits on axle
shaft. Fix Rzeppa joints are used at wheel end. Dou-
ble offset joints are used at center section.

Only rubber boots are serviceable in driveshaft
