How to Change Hood Struts on a 2015 Subaru Legacy: A Comprehensive Guide for DIY Car Repair

As a car owner, it’s important to ensure that your car is well-maintained to keep it running smoothly. One crucial part that requires periodic maintenance is the hood struts. Hood struts are an essential component of your car that help to keep your hood open when you need to perform repairs or maintenance. Over time, hood struts may wear out and require replacements. In this article, we will provide you with a comprehensive guide on how to change hood struts on a 2015 Subaru Legacy.

Importance of Changing Hood Struts

Hood struts, like any other car component, do wear out over time. When hood struts start to fail, they can no longer support the weight of your hood. This could lead to safety hazards, as the hood may suddenly close on you when you are performing maintenance, causing injury or damage to the car. Therefore, it’s important to replace worn-out struts to prevent any accidents.

Necessary Tools and Equipment

Before you dive into replacing the hood struts, make sure you have all the necessary tools and equipment. Here’s a list of items you’ll need:

  • Replacement hood struts
  • A flat-head screwdriver
  • A socket wrench set
  • Safety glasses
  • A helper to hold the hood open

Step-by-Step Instructions for Changing the Struts

  1. Open the hood and secure it with a prop rod or have someone hold it up for you.
  2. Locate the hood strut that needs replacement. Use a flat-head screwdriver to pry off the retaining clip holding the hood strut in place.
  3. Use a socket wrench to remove the nut holding the strut to the body of the car. Remove the old hood strut from the ball stud.
  4. Repeat steps 2 and 3 for the other side of the hood.
  5. Take the new hood strut and install it onto the ball stud on the body of the car.
  6. Align the other end of the hood strut with the ball stud on the underside of the hood. You may need to exert some force when doing this.
  7. Once everything is aligned, use a socket wrench to tighten the nut on the ball stud.
  8. Repeat steps 5-7 for the other side of the hood.
  9. Once both struts are installed, remove the prop rod or ask your helper to release the hood and check if everything works smoothly.

  • You may need to use a penetrating lubricant if the hood strut nuts are difficult to remove.
  • Use a socket wrench with an extension to reach the nuts in the tight spaces.
  • Consider replacing both struts at the same time, even if only one of them is worn out, to ensure that the hood stays even and level.
