Companion Flange Compensation Weights
Figure 3
This "compensation" weight was originally installed to compensate for the effect of offsetting 1/2 the mass of the propshaft because of companion flange
runout. Missing or improperly located weights may worsen the driveline disturbance. Refer to Figure 2 for companion flange and compensation weight
specifications.
