DLN-220 < UNIT DISASSEMBLY AND ASSEMBLY > [REAR FINAL DRIVE: R230] DRIVE PINION 10. Apply anti-corrosion oil to the thread and seat of drive pinion lock nut, and temporarily tighten drive pinion lock nut to drive CAUTION: Never reuse drive pinion lock nut. 11. Adjust to the drive pinion lock nut tightening torque and pinion bearing preload torque, using preload gauge [SST: ST3127S000 CAUTION: • Adjust to the lower limit of the drive pinion lock nut tight- ening torque first. • If the preload torque exceeds the specified value, replace collapsible spacer and tighten it again to adjust. Never • After adjustment, rotate drive pinion back and forth 2 to 3 times to check for unusual noise, rotation malfunction, 12. Install differential case assembly. Refer to CAUTION: Never install rear cover at this timing. 13. Check and adjust drive gear runout, tooth contact, drive gear to drive pinion backlash, and companion flange runout. Refer to Recheck above items. Readjust the above description, if necessary. 14. Check total preload torque. Refer to . 15. Install rear cover. Refer to Adjustment INFOID:0000000006222428 COMPANION FLANGE RUNOUT 1. Fit a test indicator to the inner side of the companion flange 2. Rotate companion flange to check for runout. 3. If the runout value is outside the runout limit, follow the proce- a. Check for runout while changing the phase between companion ° step, and search for the position where the runout is the minimum. b. If the runout value is still outside of the limit after the phase has been changed, possible cause will be an c. If the runout value is still outside of the limit after the check and repair, replace companion flange.
