Strut & Spring Assembly Front Driver Side - 1ASTS00644

To ensure the vehicle performs safely and as designed, we recommend replacing shocks & struts in pairs. If the damping rates are significantly different from side to side (like using different brand parts or mixing old with new) the vehicle body and wheel movement variations could cause handling irregularities. We also recommend performing an alignment after replacement. This will ensure proper tracking and protect your vehicle's tires from premature wear.

  1. step : Remove the top of the strut (1:07)
    • Lift the hood and secure it.
    • Remove the three 13 mm nuts in the engine bay securing the top of the strut.
    • Keep two of them loosely threaded just to keep the strut from flopping around while you work on the bottom half.
  2. step : Remove the wheels (1:37)
    • Use a 19 mm lug wrench to loosen the lug nuts.
    • Raise and secure the vehicle.
    • Remove the lug nuts and set the wheel aside.
  3. step : Remove the stabilizer link (2:03)
    • Use an 18 mm wrench and an 18 mm socket and ratchet to remove the stabilizer link.
    • A breaker bar can help get it loose, using the wrench to secure the back of the bolt.
  4. step : Remove the bottom of the strut (3:01)
    • Apply some penetrating oil to the two 18 mm nuts securing the strut to the steering knuckle.
    • Work the bolts out of the steering knuckle and strut.
    • Unthread the top two nuts and pull the strut down and out.
  5. step : Install the new strut (4:35)
    • Put the strut into place and thread one of the bolts through the bottom of the strut and the steering knuckle.
    • This secures the strut so you can secure the top three nuts.
    • Torque the two bolts at the bottom to 100 ft lbs.
    • Reassemble the stabilizer link.
    • Replace the wheel, using a star pattern on the lug nuts.
