Dakota R/T 2WD V8-5.9L VIN Z LDC (1999)
20.
Remove the bolts holding the universal joint clamps to the pinion yoke.
21.
Rotate the propeller shaft until the number "2" is facing straight down.
22.
Carefully slide the propeller shaft off of the transmission output shaft. Rotate the propeller shaft 900 until the number "3" is facing straight down.
Then, slide the slip yoke of the propeller shaft onto the transmission output shaft.
23.
Position the universal joint into the axle yoke. Install the universal joint strap and bolts. Tighten the bolts to 19 N.m (14 ft. lbs.).
NOTE:
MAINTAIN THE SAME AXLE PINION YOKE AND PROPELLER SHAFT YOKE ORIENTATION BY ALIGNING THE SCRIBED
REFERENCE MARKS CREATED IN STEP 13.
24.
Repeat Step 14 noting whether or not the vibration increased or decreased.
25.
Remove the bolts holding the universal joint clamps to the pinion yoke.
26.
Rotate the propeller shaft until the number "3" is facing straight down.
27.
Carefully slide the propeller shaft off of the transmission output shaft. Rotate the propeller shaft 90° until the number "4' is facing straight down.
Then, slide the slip yoke of the propeller shaft onto the transmission output shaft.
28.
Position the universal joint into the axle yoke. Install the universal joint strap and bolts. Tighten the bolts to 19 N.m (14 ft. lbs.).
NOTE:
MAINTAIN THE SAME AXLE PINION YOKE AND PROPELLER SHAFT YOKE ORIENTATION BY ALIGNING THE SCRIBED
REFERENCE MARKS CREATED IN STEP 13.
29.
Repeat Step 14 noting whether or not the vibration increased or decreased.
30.
After evaluating all four indexed positions, phase the propeller shaft to the position that produced the lowest vibration amplitude. The vibration
can be fine tuned by rotating the propshaft clockwise or counterclockwise one spline at a time.
31.
Once the optimum position between the transmission and propeller shaft has been determined, the propeller shaft must now be indexed to the rear
axle pinion yoke. Remove the bolts holding the universal clamps to the pinion yoke and rotate the propshaft 1800 from the scribed mark made in
Step 13.
NOTE:
DO NOT SEPARATE THE PROPSHAFT FROM THE TRANSMISSION OUTPUT SHAFT.
32.
Position the universal joint into the axle yoke. Install the universal joint strap and bolts. Tighten the bolts to 19 N.m (14 ft. lbs.).
33.
Repeat Step 14 again noting whether or not the vibration increased or decreased.
34.
If the peak vibration amplitudes decrease, the propshaft is indexed. If the peak vibration amplitudes increase, return the axle end of the propshaft
to its original position.
35.
Install the tire/wheel assemblies.
36.
Remove the safety stands and lower the vehicle.
