If your Jeep Grand Cherokee’s hood no longer stays open, the problem is usually worn-out hood struts. These gas-filled supports make lifting and holding the hood easy.
Over time, they lose pressure, and the hood may drop unexpectedly — which can be dangerous. Replacing them is a quick DIY job, even if you’re not an experienced mechanic.
This guide will help you swap them safely and efficiently, with clear steps, practical tips, and answers to common questions.
Why Hood Struts Fail
Hood struts use pressurized gas to provide lifting force. Heat, cold, and time cause the gas to leak or the seals to wear out. Most Jeep Grand Cherokee owners find they need to replace hood struts every 5-10 years, depending on climate and usage. If your hood starts to sag, or you hear a hissing sound, it’s time for new struts.
Tools And Materials Needed
Before you begin, gather these items:
- Replacement hood struts (check your Jeep Grand Cherokee model year)
- Flathead screwdriver
- Small socket set or pliers
- Helper (strongly recommended for safety)
- Protective gloves
Tip: Buy struts in pairs. If one fails, the other is usually close behind.
Step-by-step Replacement Guide
Changing hood struts takes about 20 minutes. Here’s how to do it:
1. Secure The Hood
First, make sure the hood won’t fall during the swap. Use a sturdy stick, broom handle, or ask someone to hold it up. Never rely on failing struts alone.
2. Locate The Hood Struts
Open the hood. You’ll see a strut on each side, connecting the hood to the fender area.
3. Remove The Old Struts
Most Jeep Grand Cherokees use ball-and-socket ends with metal clips. Here’s how to remove them:
- Insert a flathead screwdriver between the clip and the strut body.
- Gently pry the clip away — don’t fully remove it, just loosen.
- Pull the strut off the ball stud. Repeat for both ends.
- Remove the second strut the same way.
Non-obvious tip: Old struts can be under pressure. Always wear gloves and keep your face clear.
4. Install The New Struts
- Line up the new strut’s end with the ball stud.
- Push it onto the stud firmly until it clicks.
- Repeat for the other end, and then for the second strut.
Most new struts come pre-lubricated. If not, add a bit of silicone spray.
5. Test The Hood
Carefully remove your prop or have your helper step back. Slowly raise and lower the hood.
It should move smoothly and hold open on its own.
Comparing Hood Strut Options
There are several brands and types of hood struts for the Jeep Grand Cherokee. Here’s how some popular options compare:
| Brand | Warranty | Approx. Price (pair) | Durability |
|---|---|---|---|
| Mopar (OEM) | 12 months | $60-80 | High |
| StrongArm | Lifetime | $40-50 | Medium-High |
| Stabilus | 3 years | $50-60 | High |
| Generic/No-name | Varies | $20-30 | Low-Medium |
Choosing OEM or a trusted aftermarket brand is smart. Cheap struts often fail early, costing you more in the long run.
Common Mistakes To Avoid
Many first-time DIYers make simple errors that can cause damage or injury. Avoid these:
- Not supporting the hood: This can cause it to slam down, leading to injury or bent hinges.
- Forcing clips: Clips only need to be loosened, not fully removed.
- Mixing old and new struts: Always replace both for even support.
- Installing struts upside down: Check the orientation; the thicker part usually attaches to the body.
One overlooked detail: If your Jeep has aftermarket hood modifications (like bug shields), you may need stronger struts.
When To Replace Hood Struts
Not sure if your struts are bad? Here’s how to check:
| Symptom | Possible Cause |
|---|---|
| Hood slowly falls | Gas leaked from strut |
| Hood won’t stay up in cold | Worn seals |
| Visible oil or damage | Strut body failure |
| Clicking or popping | Loose mount or end |
If you notice any of these, it’s time for replacement.
Extra Tips For Success
- Check your owner’s manual for strut part numbers.
- Clean the ball studs before installing new struts for a tight fit.
- Old struts are not usually refillable or repairable — replace, don’t try to fix.
- Dispose of old struts properly, as they can be pressurized.
Another insight: If you use your hood often (for example, if you check fluids weekly), struts may wear out sooner.
