19. Install a new locking washer and a spindle 

nut. 

 

20.  Use a spanner wrench (part number 5231) to 

tighten the nut to 295 lb-ft ( 400 Nm). 
Make sure the locking washer moves free 
between the nut and the ring gear. 

 

21.  While rotating the hub, tap ring gear to check 

that the assembly is correctly fitted. Recheck 

the spindle nut torque. 

22. Back the spindle nut off 1/16 turn. 

NOTE: 

 

If the lock washer tangs do not align 
with the adjusting nut, back off the 
adjusting nut enough to align the tangs. 

 

Do not bend the lock washer tangs back 
too far. If the tangs are bent too far back, 
the lock washer will not function 

correctly.  

 

 

23. Bend the lock washer tangs into the grooves 

in the wheel bearing adjusting nut. Keep the 

tangs at a 45 degree angle to the ring gear 

hub face. 

 

24. Install the axle shaft. 

 

25. Fit coupling and sun gear.
