Corvette V8-350 5.7L (1982)

Remove wheel and tire assembly. Mount Dial Indicator J-8001 on torque control arm adjacent surface and rest pointer on flange or spindle
end.
5. Grasp brake disc and move axially (in and out) while reading movement on dial indicator. If end movement is within the .003 to .2Omm
(.001" to .008") limit, bearings do not require adjustment. If not within .003 to .2Omm (.001" to .008") limit, record reading and adjust.
a. If end play was greater than .20 mm (.008 inch), it will be necessary to reduce shim thickness, to bring end play within limits.
b. For example, if end-play reading was .33mm.(.013 inch), and the shim measured 3.66 mm (.144 inch) you will have to decrease the shim
thickness. Reducing the shim by .25mm (.010 inch), from 3.66 to 3.4Omm (.144 to .134), will also reduce, end play by .25mm (.010 inch), from
.33 to .O8mm (.013 to .003 inch).
c. If no end play was found on inspection add .08 mm (.003 inch) to the original shim as a starting point.
7. To check bearing end-play before final installation, use 1-24626 as follows:
a. Mount the outer bearing onto, the large shoulder with the large end of the bearing against the flange.
b. Place the tubular spacer, with the large end against the outer bearing and the shim selected in step 6 onto J-24626.
c. Place the tool into position in the spindle support and install inner bearing, large washer and nut. See Figure for view of these pieces and how
they compare with a sectional view of the final installed components.
d. Tighten nut to 140 Nm (100 foot-pounds) to simulate actual installed conditions.
e. Mount a dial indicator as shown in Figure and check bearing end-play, as described earlier.
f. Alter shim thickness as necessary to obtain end-play from (.03 to .2Omm) .001 inch to .008 inch. Shims are available in thicknesses from 2.46
to 3.68 Nm (.097 to .145 inch.)
g. Remove J-24626 from spindle support.
8. Install outer bearing into outer race; then install outer oil seal into bore of spindle support, making sure it is firmly seated.
9. Carefully install spindle assembly through the outer oil seal (being careful not to dislodge seal from the bore) and through the outer bearing.
10. Place the tubular spacer and the shim selected in step 7 onto the spindle shaft.
11. Place the inner bearing onto the spindle shaft.
12. Thread tool J-24490-l onto the spindle shaft, then install sleeve J-24490-2, and washer and nut. Tighten nut against sleeve, as shown in Figure The
spindle shaft will now be drawn through the bearings to its final installed position.
13. Remove J-24490- I and J-24490-2.
14. Position drive flange over spindle, making sure flange is aligned with spindle splines. Install washer and nut on spindle, then tighten nut to
specifications and install cotter pin. If specified torque does not permit cotter pin insertion, tighten nut to next flat.
15. Install caliper onto disc.
16. Install axle drive shaft, wheel and tire assembly, adjust camber cam to original position and torque all components to specifications.
17. Lower vehicle and remove from hoist.
