Special Tools

GE-7872Magnetic Base Dial Indicator Set, or equivalent

Note:This measurement procedure is intended to measure drive axlepinion input shaft runout for systems with a constant velocity (CV)joint, rubber coupling or bolt-on U-joint yoke at the driveaxle

Place the transmission in NEUTRAL.Raise and support the vehicle. Refer toLifting and Jacking the Vehicle.If equipped with a CV joint, measure the drive axle pinioninput shaft radial runout on the splined surface of the prop shaftrear CV joint housing, as close to the flange as possible:Clean the surface of the prop shaft rear CV joint housingjust ahead of the torque tube input flange.Mount a dial indicator set,GE-7872Magnetic Base Dial Indicator Set, or equivalent, and position the dial indicator tocontact the prop shaft rear CV joint housing as close to the driveaxle input flange as possible.If equipped with a rubber coupling or bolt-on U-joint yoke,measure the differential pinion input shaft radial runout on themachined surface of the flange pilot area:Mark the position of the prop shaft to the drive axle inputflange.Separate the propshaft from the drive axle inputflange.Clean the surface of the flange pilot area.Mount a dial indicator set,GE-7872Magnetic Base Dial Indicator Set, or equivalent, and position the dial indicator tocontact the pilot area as close to the drive axle input flange aspossible.If equipped with a torque tube, measure the radial runout onthe machined surface of the splined shaft:Remove the torque tube assembly from the vehicle.Clean the surface of the splined shaft.Mount a dial indicator set,GE-7872Magnetic Base Dial Indicator Set, or equivalent, and position the dial indicator tocontact the machined area as close to the end of the shaft aspossible.Rotate the drive axle input shaft by hand to locate the lowspot.Set the dial indicator to zero on the low spot.Rotate the shaft by hand and record the amount of radialrunout.Compare the runout of the shaft to the runout tolerancespecifications guidelines.If the drive axle input shaft runout exceeds thespecification, the flange requires replacement.
