2014-2023 Lexus GX460 Hood Lift Support: Why It Fails and How to Replace It
This guide covers the common failure symptoms, replacement process, and costs for the hood lift supports on the 2014-2023 Lexus GX460.
- Failing hood struts are a major safety hazard; the hood can slam shut without warning, causing injury.
- Replacement is a very easy, 10-minute DIY job requiring only a small flathead screwdriver.
- Always replace hood struts in pairs to ensure even pressure and prevent premature wear.
- Buying new aftermarket struts is the recommended and most cost-effective solution, as used struts have an unknown lifespan.
Symptoms of a Failing Hood Lift Support
The failure of a hood lift support is usually gradual, but it can sometimes be sudden. The most significant risk of a failing support is the hood unexpectedly slamming shut, which can cause serious injury if you are working in the engine bay. Be aware of the following symptoms:
- Hood Slowly Drifts Closed: This is the most common early sign of failure. You open the hood, and it stays for a moment, but then slowly starts to close on its own. This happens because the gas pressure inside the strut has become too low to counteract the hood's weight.
- Hood Won't Stay Open at All: If the struts have lost all their pressure, the hood will not stay open without being propped up manually.
- Hood Suddenly Slams Shut: This is a dangerous symptom. A worn-out strut might seem to hold the hood initially, but then fail without warning. This is a clear sign that immediate replacement is necessary.
- Weakness in Cold Weather: Gas pressure is affected by temperature. You might first notice that your hood struts are weak during colder months, as the reduced pressure struggles to hold the hood.
- Visible Oil or Residue: The struts contain a small amount of oil for lubrication. If you see oily residue on the strut's body, it indicates that the seals have failed and are leaking.
Warning: A failing hood support is a significant safety hazard. Never work under a hood that cannot support its own weight without using a separate, sturdy prop rod or having a helper hold the hood.
Known Issues, TSBs, and Recalls
As of early 2026, there are no specific recalls or Technical Service Bulletins (TSBs) from Lexus or the National Highway Traffic Safety Administration (NHTSA) for hood lift support failure on the 2014-2023 Lexus GX460. Failure is typically due to normal wear and tear over time. While a TSB exists for hood flutter on the newer generation GX 550, this is an unrelated issue concerning the hood panel's bonding, 🎬 Watch: Learn more about the GX 550 hood flutter issue. not the lift supports.
Buying a Used Hood Lift Support
While purchasing used parts is often a great value, it is generally not recommended for hood lift supports. These are wear-and-tear items with a finite lifespan, typically lasting 3-5 years or more depending on use and climate.
The internal gas pressure, which is the critical component, cannot be visually inspected. A used strut may look perfect but have very little life left. Given the low cost of new aftermarket replacements and the critical safety function of this part, buying new is a much safer and more reliable option. If you do consider a used OEM part, only buy from a reputable recycler that offers a warranty and check the vehicle's mileage—a part from a low-mileage vehicle is preferable, but provides no guarantee of longevity.
Replacement Guide
Replacing the hood lift supports on a Lexus GX460 is a very simple DIY task that can be completed in about 10-15 minutes 🎬 See this quick walkthrough of the GX460 strut replacement process. with a single tool.
Difficulty: 1/5
Tools Needed: Small flathead screwdriver
Steps:
- Prop the Hood Open: This is the most important safety step. Have a helper hold the hood open or use a secure prop rod. Do not rely on the old, failing struts.
- Remove the Old Strut: The struts are attached to ball joints on the hood and the fender. At each end, there is a small metal retaining clip. Insert a small flathead screwdriver under the clip and pry it outwards slightly. This will release the tension, and you can pull the strut end off the ball joint. Do this for both the top and bottom of one strut.
- Install the New Strut: Most new struts simply snap into place. Align the new strut's end connector with the ball joint and press firmly until it clicks securely. There is no need to pry the clip on the new part. Install the new strut in the same orientation as the old one (usually with the cylinder body up).
- Replace in Pairs: Always replace both the left and right hood struts at the same time. Replacing only one will cause uneven pressure and wear, and the new strut will fail prematurely.
- Test: After installing both new struts, carefully remove your prop rod and test the hood's operation. It should lift smoothly and hold its position firmly.
Pro Tip: Before snapping the new struts on, wipe the ball joints on the vehicle clean with a rag. Some mechanics apply a small amount of grease to the ball joint for smoother long-term operation.

Frequently Asked Questions
Do I have to replace both hood struts at the same time?
Yes. It is highly recommended to replace both struts as a pair. They wear out at similar rates, and a new strut will have much more pressure than the remaining old one. This imbalance can cause twisting stress on the hood and will cause the new strut to fail much faster.
How long do hood lift supports last?
The lifespan of hood struts is typically between 3 to 10 years, but this can be affected by climate (extreme heat or cold shortens life) and how frequently the hood is opened.
Is it dangerous if my hood struts are failing?
Yes. The primary danger is the hood suddenly slamming shut while you are inspecting the engine or performing maintenance, which could cause serious head or hand injuries. It is a safety issue that should be addressed promptly.
Why are my new aftermarket struts so hard to close?
New struts, especially aftermarket ones, can sometimes be over-pressurized compared to the worn-out OEM parts they are replacing. This can make the hood harder to close initially. This is generally normal and may lessen slightly over time. Ensure you purchased the correct part for your specific vehicle, as a strut designed for a heavier hood will be much stronger.
