NOISE - DRIVELINE CLUNK - AUTOMATIC TRANSMISSION/ONE-PIECE DRIVESHAFT
LIGHT TRUCKS 1981-83 E & F100-350
A driveline clunk/grunt noise at start-up and stop driving modes on some 1981-1983 light truck vehicles, equipped with one-piece driveshafts and C4,
C5, C6 or AOD automatic transmissions, may be caused by slip yoke bind-up. To service this condition, perform the following procedure:
^
Raise the vehicle on a hoist.
^
Remove the driveshaft assembly.
NOTE:
Mark the driveshaft in relation to the companion flange as it must be reinstalled in its original position.
^
Inspect extension housing seal and replace as required.
^
Remove (and discard) slip yoke from the driveshaft.
^
Using the following chart, install a replacement slip yoke (blind spline) on the driveshaft. Grease the slip yoke 360~ with ESA-M1C75-B
multi-purpose long life lubricant.
NOTE:
Complete lubricant coverage (no dry spots on spline) is necessary to ensure proper break-in and prevention of recurring clunk.
^
Reinstall driveshaft and torque U-bolts 8-15 ft.lbs.
^
Road test.
NOTE:
Vehicle should reach normal operating temperature during road test in order to properly check transmission oil level. Add transmission
fluid, as required, per Shop Manual Section 17-01.
