SUSPENSION AND AXLE –
8. REMOVE RH SIDE OIL SEAL
Using SST, remove the oil seal.
SST 09308–00010
9. CHECK RING GEAR RUNOUT
Using a dial indicator, measure the ring gear runout.
Maximum runout: 0.07 mm (0.0028 in.)
If the runout is greater than maximum, replace the ring
gear and drive pinion as a set.
10. CHECK RING GEAR BACKLASH
(a) Fix the dial indicator on the tooth surface at a 90
angle.
(b) Holding the drive pinion flange, measure the ring
gear backlash.
Ring gear backlash: 0.13 – 0.18 mm
If the backlash is not within specification, adjust the ring
gear backlash.
HINT: Measure from three or more places on the cir–
cumference of the ring gear.
11. INSPECT TOOTH CONTACT BETWEEN RING GEAR AND
DRIVE PINION (SEE STEP 7 ON PAGE SA–100)
12. MEASURE DRIVE PINION PRELOAD
Using a torque gauge, measure the preload of the back–
lash between the drive pinion and ring gear.
Preload (starting):
0.6 – 1.0 N–m (6 – 10 kgf–cm, 5.2 – 8.7 in.–Ibf )
13. CHECK TOTAL PRELOAD
Using a torque gauge, measure the total preload.
Total preload (starting):
Add drive pinion preload
0.4 – 0.6 N–m
(4 – 6 kgf–cm, 3.5 – 5.2 in.–Ibf)
