If the vehicle is equipped with a ride height sensor:
-
Remove and discard the nut
that attaches the stabilizer bar link to the LH front spring and damper
assembly, and then move the link aside.
NoteCounter-hold the ball joint while loosening the nut.Tip: If needed, use a pry bar to release the end link.Tip: Use of the following tool(s) is recommended:
- 18 mm combination wrench
