ArvinMeritor Maintenance Manual MM-0361 (Revised 04-10)
6. Inspect the housing seal and thrust washer to verify that these
pieces are correctly installed. Install the universal joint into the
housing. Align the inner shaft splines with the splines of the
differential side gear.
7. Pack the thrust washer rollers with grease before assembly.
8. Install the thrust bearing against the journal on the lower cap.
9. Place the knuckle into its correct position over the end of the
housing. Align the knuckle bores with the housing socket
bores.
10. Install the lower cap assembly through the bottom bores of the
knuckle and housing until the cap is against the knuckle.
11. Install the capscrews and tighten to the correct torque. Refer to
Section 8.
12. Install the shims and oil seal against the base of the upper cap.
Use the same thickness shim pack that was removed during
disassembly. The shim pack must contain a minimum of three
shims.
13. Install the cap assembly through the upper bores of the
knuckle and housing until the cap is against the knuckle.
14. Install the capscrews and tighten to the correct torque. Refer to
Section 8.
15. Check the steering knuckle end play.
A. Support the vehicle with safety stands under the axle
housing.
B. Place a magnetic base dial indicator into position on the
housing. Figure 6.7.
NOTE: If necessary, remove the grease fitting from the lower
knuckle cap to prevent damage.
C. Use a jack to place pressure onto the lower knuckle cap.
Set the dial indicator to ZERO.
D. Fully release the jack pressure and read the end play on
the dial indicator. Correct end play is 0.005-0.015-inch
(0.127-0.381 mm). Remove or add shims from between
the upper knuckle cap and steering knuckle to obtain the
correct end play.
Figure 6.7
16. Check the knuckle bearing preload.
A. Fasten a soft wire or cord to the tie rod arm. Attach a
pound scale to the opposite end of the wire or cord. Hold
the outer shaft of the universal joint away from the
knuckle opening and pull on the pound scale to rotate the
knuckle. Read the pounds on the scale. Read the pull
necessary to rotate the knuckle, not the pull necessary to
start the movement. Figure 6.8.
B. The pounds shown on the scale must be 10-30 lbs
(4.5-13.5 kg). The correct rotating torque is 8-25 lb-ft
(20.8-33.9 Nm). @
