  2.  
  3. Remove the wheel(s).
  4.  
  5. Disconnect the stabilizer (sway bar) link at the control arm.

To install:
  1. If bushings are to be replaced, note that the right and left bushings are not interchangeable. The right side bushing should be turned so that the small slots point horizontally when installed.
  2.  
  3. Install the bracket onto the control arm. The nut should be tightened only enough to hold securely. The washer should be able to be turned with your fingers after the nut is on.
  4.  
  5. Attach the control arm. Install the front retaining bolt and nut; tighten the nut only a few turns onto the bolt.
  6.  
  7. Guide the stabilizer link into position. Attach it loosely with its nut and bolt.
  8.
