Rear struts:
Take out on your car first !
  • vegetable oil (small)
  • Wrenches 14mm-15mm-etc
  • torque wrench
  • impact wrench
  • 14mm (caliper)
  • 15mm socket/wrench (sway bar end link/strut housing bolts in trunk)
  • 19mm (lug nuts)
  • 21mm long socket (lower strut bolts)
  • SMALL hammer
  • Scroll down to 13 under installation (chapters specifications) 4 torque specs

  1. In the trunk compartment, move the side trim away to expose the strut (3) upper mounting fasteners . Pull the rubber cap off the top of the strut, if equipped, then loosen, but do not remove, the mounting fasteners

  • long wrench 🔧 15mm
  • loosen but do not remove (I think you can keep 1 in place to hold it till later on before you do final removal)

2. Loosen the rear wheel lug nuts. Block the front wheels to keep the vehicle from rolling, then raise the rear of the vehicle and support it securely on jackstand. Remove the rear wheel.

  • 19mm
  • Should be able to spin wheels once off ground (Clearance)

3. Remove the brake caliper so you have more room to take out Strut-to-knuckle bolts! (2 bolts) (don't tighten with impact wrench) Place caliper safely to the side!

4. Detach the stabilizer bar link (sway bar link) from the strut (Detach the stabilizer bar link from the stabilizer bar) SEE PHOTOS, ****NEXT push the bar out and too the right or left
  • 1 foot pound torque
  • 15mm socket
  • one ratchet behind and unscrew from front (at same time)
  • push sway bar out then move to right side
  • If it's too tight then the shop used an impact wrench!

5. Mark the relationship of the strut to the knuckle (these marks will be used during installation to ensure that the camber angle is returned to its original setting)

6. Remove the strut-to-knuckle nuts while holding the oval shaped bolt heads with a wrench (might need an impact wrench for just bolt heads,still have to use a hammer for actual bolt). Remove the bolts by striking the end with a hammer to push them out of the knuckle and strut.

  • Caution: Do not attempt to turn the strut mounting bolts. These bolts are serrated to fit tightly when seated against the strut mounting flange and in the holes of the knuckle. Use a hammer !!!!!

7. Separate the strut from the rear knuckle , then remove the upper mounting nuts and remove the strut. (Secure the rear knuckle so that it does not fall outward and damage the brake hose or ABS wire harness, if equipped)

  • when removing strut push up and twist then pull down (push down hard,move side to side if you have at same time, then it’ll pop down and the strut will come forward)
  • Sway bar links are sometimes replaced!



  1. Guide the knuckle into the strut flange while placing the upper part of the strut in position where it mounts to the body. *Install the upper mounting nuts finger-tight to hold the strut in place.
Next Install the strut lower mounting fasteners (two bolts) using a soft-face hammer or mallet (align the marks made in Step 4).

Then Install the bolt heads. Tighten the nuts to the torque listed.
  • You're going to need your light pointed at the top of the strut right before you put those 3 bolts in!
  • Before putting the bolts in you can lift on the brake assembly with your hand to properly align the bolts with your marker (wiggle to perfection).
  • If you need help you can put a jack under and lift up till strut goes into place!
  • You can either follow the instructions or the photo order (both exactly the same but you might not need to use jack, either way have proper lighting pointing to top of assembly when guiding top of strut to the 3 top fasteners). Also the only difference is the photo shows you guiding the strut on to knuckle versus starting with 3 screws first! Book says guide strut into upper mount first then pull knuckle up!

2. Install caliper by properly lubing and installing 2 bolts.
  • Watch video 2:30-3:50

3. Install the stabilizer bar link
  • Lubricate the inside and outside of the bushings with vegetable oil (used in cooking) to simplify reassembly. Caution: Don’t use petroleum or mineral-based lubricants or brake fluid - they will lead to deterioration of the bushings. These bushings are split so that you can install them without having to slide them onto the ends of the stabilizer bar.)
  • Tighten the link and bracket fasteners to the torque values listed in this Chapter’s Specifications.
  • Hold from back with a wrench as you tighten.

4. Install the wheel and lug nuts, then lower the vehicle
  • tighten the lug nuts to the torque listed in the Chapter 1 Specifications
  • Clean brake with microfiber rag

5. Tighten the upper mounting nuts to the torque listed in this Chapter’s Specifications .

6. Have the wheel alignment checked and, if necessary, adjusted.!!!
