Proper use of front axle' shaft ASSY 95AC-23 and
95 AC-25
95AC axle shaft is available in two different sizes to suit the
differential spindle in the transmission; DOJ spline 23 teeth
type [spline dia. 27 mm (1.06 in) dia.] and DOJ spline 25
teeth type [spline dia. 30 mm (1.18 in) dia.]. These shafts
must be used properly according to the "Application Table".
When replacing a single DOJ unit or axle shaft ASSY, carefully
check the actual vehicle to avoid improper use of axle shaft.
The axle shafts 95AC-23 and 95AC-25 can be distinguished by
the different shape of the DOJ small end as shown in the
figure.
Improper combination of transmission spindle and DOJ spline
will result in the following faulty conditions.
a. 87AC-23, 95AC-23 combined with thick spindle [30 mm
(1.18 in) dia.]:
The axle shaft cannot be installed because the D OJ spline
diameter is small [27 mm (1.06 in) dia.].
b. 87AC-25, 95AC-25 combined with thin spindle [27 mm
(1.06 in) dia.] :
A large play will be formed between DOJ and spindle. (Fitting
the DOJ to spindle is too loose.) At the time of vehicle's
starting the spring pin will break, and a large noise will be
generated, then the vehicle will fail to go forward (FWD mode)
as the front differential rotates idly.
