3. 

INSPECT RUNOUT OF INTERMEDIATE  SHAFT AND
PROPELLER SHAFT

Maximum runout:

0.8 mm (0.031 in.)

If the runout is greater than the maximum, replace the propel-
ler shaft assembly.

4. 

INSPECT SPIDER BEARING

•

Check if the spider bearing rotates smoothly.

•

Check if there is any play in the spider bearing.

If necessary, replace the propeller shaft assembly.

5. INSTALL CENTER SUPPORT BEARING ON

INTERMEDIATE SHAFT
HINT: Install the center support bearing in the direction, as
shown and install the 2 washers.

INSTALL FLANGE ON INTERMEDIATE SHAFT

(a)  Coat the spline of the intermediate with MP grease.
(b)  Place the flange on the shaft and align the matchmarks.

HINT: If replacing either the center flange or intermediate
shaft, reassemble them so that the front yoke of the inter-
mediate shaft and the rear yoke of the propeller shaft are fac-
ing in the same direction.

(c)  Using SST to hold the flange, press the bearing into position

by tightening down a new nut.

If using a new propeller shaft (w/ Phasemarks)
Install the propeller shaft phasemarks and differential phase-
marks so that their respective alignment phasemarks match.
If the propeller shaft phasemarks and differential phase-
marks do not align, install the propeller shaft and differential
alignment phasemarks are as close together as possible.
