Most Mopar 8 3/4-inch rearends have an axle adjuster on the passenger-side axleshaft. After the axles are in, there should be about 0.008- to 0.018-inch endplay or problems may result. To adjust endplay, rotate the notched adjuster ring. On rearends so equipped (such as a Mopar 8 3/4) be sure to reinstall the endplay adjuster ring retainer clip that mounts using one of the axle bearing retaining plate nuts. On rearends without an adjuster ring, axle endplay can be adjusted using different thickness gaskets/shims.
