Santa Fe GLS V6-2.7L (2002)
1. Fix the side gear with a wedge so it cannot move and measure the differential gear backlash with a dial indicator on the pinion gear.
NOTE: Take the measurements at two places (4 places for LSD) on the pinion gear
Standard value: 0 - 0.076 mm (0 - 0.003 inch)
Limit: 0.2 mm (0.008 inch)
2. If the backlash exceeds the limit, adjust using side bearing spacers.
NOTE: If adjustment is impossible, replace the side gear and pinion gears as a set.
FINAL DRIVE GEAR TOOTH CONTACT
Check the final drive gear tooth contact by following the steps below:
1. Apply a thin, uniform coat of machine blue to both surfaces of the drive gear teeth.
2. Insert a brass rod between the differential carrier and the differential case, and then rotate the companion flange by hand (once in the normal
direction, and then once in the reverse direction) while applying a load to the drive gear so that some torque (approximately 25 - 30 kg.cm) is
applied to the drive pinion.
CAUTION: If the drive gear is rotated too much, the tooth contact pattern will become unclear and difficult to check.
3. Check the tooth contact pattern.
