Reassembly

1. Lubricate all components with recommended 

oil and lightly oil the differential bolt threads.

2. Secure rear half of differential carrier in a soft 

jawed vice.

3. Fit each planet gear to its respective cross 

shaft, fit new dished thrust washer to each 
gear.

4. Fit cross shafts, planet gears and dished thrust 

washers in rear half of carrier.Ensure that 
cross shafts are fitted correctly. Do not fit 
the sun gear into the rear half carrier at this 
stage.

5. Fit retaining ring.
6. Fit a 1.05 mm (0.04 in) thrust washer to sun 

gear from front half of carrier. Position gear in 
front half of carrier.

7. Ensuring that assembly marks are aligned, fit 

both halves of carrier together. 

8. Fit the differential carrier bolts and, working in a 

diagonal sequence, tighten the bolts to 60 Nm, 
(44 lbf.ft).

9. Insert the front output shaft into the front half of 

the carrier and check that the gears rotate 
freely.

10. Fit output flange on to the splines of the output 

shaft, but do not fit flange nut at this stage.

11. Fit transmission brake drum to output flange 

and secure the drum using 2 nuts.

12. Secure a length of cord around the drum and 

attach one end of the cord to a spring balance.

13. Pull on the spring balance and note the load at 

which the brake drum starts to turn. Used 
gears should rotate smoothly, while new 
gears will have a 'notchy' feel as they rotate.

14. Compare the figure obtained with the following.

l

Used gears = 0.45 kg (1.0 lb)

l

New gears = 1.72 kg (3.8 lb)

15. If the load to turn figure is below the specified 

limits, proceed as follows.

16. Remove the front output shaft and brake drum.
17. Remove the 8 bolts securing the two halves of 

the differential carrier

18. Separate the differential carrier and remove the 

sun gear and thrust washer from the front half.

19. Select a thicker thrust washer from the range 

available. 5 different thrust washers are 
available, rising in increments of 0.10 mm 
(0.004 in) from 1.05 mm to 1.45 mm (0.04 to 
0.06 in).

20. Repeat steps 7 to 19 as necessary until the 

load to turn figure is as specified

21. When specified load to turn is obtained, 

proceed as follows.

22. Remove the front output shaft and brake drum.
23. Remove the 8 bolts securing the two halves of 

the differential carrier

24. Separate the differential carrier and remove the 

sun gear and thrust washer from the front 
half.Retain the selected thrust washer with 
its sun gear.
