Stock Endlink Removal

  1. Park your car in a flat, level area and allow it to cool down properly.

  2. Using a 10mm wrench, remove the negative terminal of the battery.

  3. Jack your car up and support it properly, either using a lift, ramps, or jack and jack stands.

  4. Lay a blanket or cardboard down under the car, or grab a creeper.  In this case his name is Andrew

  5. To remove the end links, start with loosening the 14mm bolt holding the sway bar to the lower control arm using a socket on one side and a wrench on the other.

  6. Use a 5mm allen to hold the center of the end link where it goes through the sway bar, and use your 14mm wrench to remove the nut.

  7. Afterward you should be able to remove the entire endlink from the car.


  1. Fish the rear swaybar around the exhaust.  Install the swaybar bushing brackets but only secure the top bolt for now.

  2. You can now tighten up all the bolts for the rear sway bar.

  3. Go out and Enjoy!
