Sterling Trucks Acterra MX - Manual (Page 99)

If the driveshaft tube requires straightening or
replacement, balance the repaired driveshaft be-
fore installing it. See Group 41 of the
Acterra ®
Workshop Manual.
7. Check the driveshaft for missing balance
weights, and for debris build-up. Remove any
build-up. If any balance weights are missing, re-
move the driveshaft and have it balanced; see
Group 41 of the
Acterra ® Workshop Manual.
8. For driveshafts with slip-joints, check that the
yoke plug is not loose or missing. See
Fig. 4 ,
Ref. 2. Replace the yoke plug if needed. If the
yoke plug is missing, the splined shaft may be
hitting the yoke plug and knocking it out; check
the driveshaft for proper length.
