What is a Hood Support Strut?

A support strut is the long tube that causes the gentle hissing noise when the hood is raised. They are attached to the frame and hood, and when the hood is opened and closed, they extend and contract respectively. They hold the weight of the hood while opening and closing, and prevent the hood from falling when in its raised position. These are a very effective tool for ease of access to the engine bay, as a hood is much heavier than it looks`.

How do Hood Support Struts work?

Since the hood support strut is attached to the hood and the chassis of the vehicle, the support struts must be able to extend and retract without bending or breaking away from the mounts. Also, due to the weight of the hood, they must be able to hold weight, yet be balanced enough to allow the average person to pull the hood down. For these purposes. the part was designed as a very small shock absorber. Filled with inert gas or hydraulic fluid, this strut (or shock) is always attempting to extend itself. Internal pressures push two rods against each other, and one is mounted inside the the one. This causes the hood to be very easy to lift, as the support struts are doing most of the work. however, the hood struts cannot be too strong. They must only have enough force to push the hood open, with the addition of a few additional pounds of holding force. This prevents the hood from falling when the wind blows, or if someone bumps it while it is open. When the hood is closed, one half of the strut will slide back into the other half, being forced in by the user placing constant pressure on the hood until it is closed.

What are the symptoms of a bad Hood Support Strut?

We have all noticed an old car with a stick holding up the hood or hatch. That is because the owner has not replaced the support strut for that component. Also, if you have ever tried opening a hood or hatch, and the support strut had failed, you would know immediately as the entire weight of the panel would be resisting the lifting action. Also, the end of one of these hood support rods may be rattling around while driving, and opening the hood may show it is swinging freely, or falls off completely. When they separate from their mounting points, this is sure to happen.

Can I drive with a bad Hood Support Strut?

There is nothing like a properly operating vehicle, especially when all of the accessories function, like the hood. on the other hand, a heavy hood can make getting to the engine bay a daunting task for larger vehicles. Replacing these struts is not a necessary endeavour, but it can certainly add to the quality of life of the owner of the vehicle. Fix this one at your convenience, or when you are tired of dealing with the hood.

How often do Hood Support Struts need replacement?

These fail quite often. In fact, many luxury vehicles list inspection or replacement of the hood struts as soon as 60,000 miles or 5 years. The rate of failure should not be this quick, but with lots of use of the hood, they may fail even faster. More typically, vehicles should be able to use the same hood struts for much longer, maybe even twice as long.

How are Hood Support Strut issues diagnosed?

Anyone can diagnose these struts without any prior knowledge of how the part functions. All that is needed to know is that they hold the hood up securely. When they fail to keep the hood up unless it is pulled down to the closed position, it is time to replace them. Also, if the hood support struts are able to rattle against their mounting points, they will likely need replacement due to this condition. This will prevent wear from allowing the strut to separate from the mounting point.

How are Hood Support Struts replaced?

For nearly all hood support struts the replacement procedure is the same, and takes less than one minute. Some will require the removal of a fastener of some type, but most require the removal of a flat spring which is curved around the assembly. The flat spring will be located on the ball at the end of the strut, and using a screwdriver or pick, the spring can be gently pulled back, which causes it to release the circular mounting point inside the ball. Once done, the strut pulls off, so ensure the hood has secondary support already in place. A broom handle does a very nice job of this at home. The new strut will pop right on without pulling the spring back, and the other end must be replaced in the same way. Ensure they are replaced as a set.

RepairPal Recommendations for Hood Support Strut issues

Never replace only one support strut, unless it was physically damaged by an external force. When one fails, the other must do every bit of the work for both, so replacing one will cause undue stress on the new one. The old, worn out strut will fail more quickly, and the new strut will wear twice as fast. This will lead to early replacement of three struts instead of two.

What to look out for when dealing with Hood Support Strut issues

When the hood support struts are worn out, no one should work under the hood without a secondary support. Especially if the existing hood support struts can be made to stay in the opened position after a few tries, as this can lead to the belief that the hood will not crash down. The slightest wind or jarring of the vehicle can cause the hood to swing down violently. The use of a prop rod, like a strong piece of wood or a broom handle, is necessary if there is servicing being conducted. Also, there should be someone there to hold the hood just in case. The weight of the hood is very much heavier than it seems with working support rods.

Can I replace the Hood Support Strut myself?

This is a simple fix for any DIYer, or just someone who does not want to spend money at the shop. With the most basic tool, a helper to hold the hood, and a few minutes, anyone can easily perform this task. Be aware, however, that the struts can be hard to compress once they are freed of their manufacturer packaging straps, as they are packed compressed and will extend forcefully when the straps are cut/removed.
