Carrier Bearing End Play
- Place bearing cup over each carrier bearing. Install carrier assembly (without drive gear) into axle housing. Install a .142" (3.60 mm) shim on outer side of each carrier bearing cup on 7 9/16" drive axles. On 8 1/2" drive axles, install a .080" (2.03 mm) shim on each side of carrier bearing cup. Shim should be located between bearing cup and housing.
- Install bearing caps and tighten bolts finge tight. Mount dial indicator to housing so indicator button touches ring gear face of carrier case. Prying between shims and housing, move assembly to one side. Zero dial indicator, then pry assembly to opposite side. Read and record indicator reading. Do not zero or read indicator while prying.
- Amount read on indicator (when divided by 2; one for each side) is the thickness of shims needed in order to arrive at a no end play condition. Shims are available in thicknesses of .142" (3.60 mm) to .174" (4.41 mm) in .002" (.050 mm) increments.
- When all side play is eliminated, check drive gear face of case for runout by rotating carrier and reading dial indicator. Runout should not exceed .002" (.050 mm). Remove carrier from housing and retain shims used to check end play. See Fig 1
