SERVICE ADJUSTMENT PROCEDURES
FRONT AXLE TOTAL BACKLASH CHECK E26FBAA

  • 1. If the vehicle vibrates and produces a booming sound, measure the front axle total backlash by the following procedure to see if the differential carrier assembly requires removal.
    • (1) On vehicles with free-wheeling hub, shift into 4wheel drive position.

NOTE

On vehicles with manual free-wheeling hub, place the control handle in the LOCK position.

On vehicles with automatic free-wheeling hub, place the transfer shift lever in 4H position and drive the vehicle 1 to 2 meters (3.3 to 6.5 ft.) to engage the hub with the drive shaft.

For vehicles with super select 4WD, place the transfer control lever in 4H position and drive the vehicle until the 4WD indicator changes from flashing to illuminated.

  • (2) Hold the wheels and place the transfer control lever in 2H position.
  • (3) Turn the companion flange clockwise until all play is removed. Mate mark on the dust cover of the companion flange with that on the differential carrier.
  • (4) Turn the companion flange counterclockwise until all play is removed and measure the amount of distance through which the mating marks moved.
Limit:
Vehicles with free-wheeling hub
14 mm (0.55 in.) Vehicles without free-wheeling hub 11 mm (0.43 in.)

2. If the backlash exceeds the limit, remove the differential carrier assembly and final drive gear, and check for differential gear meshing condition and drive shaft or inner shaft spline looseness.

Remove the cover and gasket. Hold the special tool in a vise, and install the differential carrier assembly to the special tool.

FINAL DRIVE GEAR BACKLASH

Check the final drive gear backlash by following the steps below.

(1) With the drive pinion locked in place, measure the final drive gear backlash with a dial indicator on the drive gear.

NOTE

Measure at four points or more on the circumference of the drive gear.

Standard value: 0.11-0.16 mm (0.0043-0.0063 in.)

(2) If the backlash is not within the standard value, adjust it by using the side bearing adjustment spacers.

DRIVE GEAR RUNOUT

Check the drive gear runout by following the steps below.(1) Measure the drive gear runout at the shoulder on the reverse side of the drive gear.

Limit: 0.05 mm (0.0020 in.)

(2) If the runout exceeds the limit, check for improper tightening of the drive gear and differential case.

DIFFERENTIAL GEAR BACKLASH <EXCLUDING 4 PINION DIFFERENTIAL>

Check the differential gear backlash by following the steps below.

(1) While locking the side gear with the wedge, measure the differential gear backlash with a dial indicator on the pinion gear.

NOTE

The measurement should be made for both pinion gears individually.

Standard value: 0–0.076 mm (0–0.0030 in.) Limit: 0.2 mm (0.0079 in.)

(2) If the backlash exceeds the limit, adjust by using the side gear thrust spacers.

Page 48

FINAL DRIVE GEAR TOOTH CONTACT

Check the final drive gear tooth contact by following the steps below.

  • 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 the revolution torque [approximately 2.5–3.0 Nm (25–30 kgcm, 28–33 in.lbs.)] 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 condition of the drive gear and drive pinion.

Page 49

NOTE

Checking the tooth contact pattern is the way to confirm that the adjustments of the pinion height and backlash have been done properly. Continue to adjust the pinion height and backlash until the tooth contact pattern resembles the standard pattern.

If, even after adjustments have been made, the correct tooth contact pattern cannot be obtained, it means that the drive gear and the drive pinion have become worn beyond the allowable limit. Replace the gear set.
