REMOVAL & INSTALLATION



Mirage

NOTE
If the vehicle is going to be rolled while the halfshafts are out of the vehicle, obtain 2 outer CV-joints or proper equivalent tools and install to the hubs. If the vehicle is rolled without the proper torque applied to the front wheel bearings, the bearings will no longer be usable.


NOTE
The suspension components should not be tightened until the vehicles weight is resting on the ground.

  1. Remove the battery and battery tray.
  2.  
  3. Remove the air cleaner assembly and vacuum hoses.
  4.
