  1. Raise the vehicle and support it safely.
  2.  
  3. Remove the wheel and tire assemblies.
  4.  
  5. If equipped with rear disc brakes, remove the caliper assembly.
  6.  
  7. Remove the grease cap and the hub nut.

Diamante

NOTE
The hub assembly is not repairable; if defective, replacement is the only option. If the hub is removed for any reason it must be replaced.

  1. Raise and support vehicle safely.
  2.  
  3. Remove the both of the rear wheels.
  4.  
  5. Remove the caliper and the brake disc. Support the caliper with wire to prevent stress to the brake hose.
  6.  
  7. If equipped with ABS, remove the bolt holding the speed sensor to the trailing arm and remove the sensor.
  8.  


NOTE
The speed sensor has a pole piece projecting from it. This exposed tip must be protected from impact or scratches. Do not allow the pole piece to contact the toothed wheel during removal or installation.

  1. Remove the grease cap, self-locking nut and tongued washer.
  2.  


NOTE
Do not use an air gun to remove the hub locknut.

  1. Remove the rear hub assembly from the spindle.
  2.  
  3. Remove the bolts that secure the ABS sensor ring to the hub and remove the ring from the hub.
  4.  

To install

  1. Secure the sensor ring to the hub assembly and tighten the mounting bolts.
  2.  
  3. Install the hub assembly, tongued washer and a new self-locking nut. Tighten the nut to 166 ft. lbs. (230 Nm), align with the indentation in the spindle, and crimp.
  4.  
  5. Using a rope around the hub bolts and a spring balance, measure the resistance necessary to rotate the hub. If the resistance exceeds 7 ft. lbs. (13 Nm), loosen and retighten the locknut. If the resistance still exceeds the specification, the hub must be replaced.
  6.  
  7. Using a dial indicator, measure the hub endplay. The endplay should be 0.002 inches (0.05mm) or less.
  8.  
  9. Install the brake rotor and caliper assembly.
  10.  
  11. Install the speed sensor to the knuckle.
  12.  


NOTE
Route the speed sensor cable correctly. Improper installation may cause cable damage and system failure. Use the white stripe on the outer insulation to keep the sensor harness properly positioned.

  1. Use a brass or other non-magnetic feeler gauge to check the air gap between the tip of the pole piece and the toothed wheel. Correct gap is 0.008-0.028 in. (0.2-0.7mm). Tighten the sensor bracket nut with the sensor located so the gap is the same at several points on the toothed wheel. If the gap is incorrect, it is likely that the toothed wheel is worn or improperly installed.
  2.  
  3. Bleed the brake system and install the rear wheels.
