If your Jeep Liberty’s rear window won’t stay up, the struts (sometimes called lift supports or gas springs) are probably worn out. These small but vital parts hold your rear glass open, making it safe and easy to load gear or get groceries.
Replacing them is a smart DIY repair. It saves money, takes less than an hour, and requires only basic tools. This guide will walk you through the process, share tips, and help you avoid common mistakes.
Understanding Rear Window Struts
The rear window struts are pressurized rods that use gas to hold the rear glass open. Over time, the gas can leak, or the seals may fail. When that happens, the window drops quickly or won’t stay up at all. This isn’t just annoying—it can be dangerous if the window slams down unexpectedly.
Symptoms Of Bad Struts
- The rear window won’t stay up
- The window falls faster than normal
- You hear hissing or see oil near the strut ends
Replacing struts is a simple solution. You don’t need special skills, and the job is the same for most Jeep Liberty models from 2002 to 2012.
Tools And Parts You’ll Need
Before starting, gather these items:
- New rear window struts (make sure they fit your year/model)
- Flathead screwdriver
- Small socket set or wrench (8mm or 10mm usually)
- Safety glasses and gloves
- A helper or prop rod (like a broomstick)
Not all struts are equal. Cheaper struts often wear out faster or don’t hold as much weight. It’s worth buying from a trusted brand or checking reviews.
Here’s a quick comparison of popular brands:
| Brand | Warranty | Price Range (Pair) | User Ratings |
|---|---|---|---|
| StrongArm | 1 year | $30–$45 | 4.6/5 |
| Stabilus | 2 years | $40–$60 | 4.8/5 |
| Monroe | Limited Lifetime | $35–$55 | 4.7/5 |
Pro tip: Double-check the strut length and attachment style before buying. Some Jeep Liberty models have slightly different mounts.
Step-by-step Replacement Guide
Replacing the rear window struts isn’t hard, but it’s important to follow the steps carefully for safety.
1. Secure The Rear Window
Before removing any strut, support the window. The glass is heavier than it looks and can fall suddenly.
- Have a helper hold it open, or
- Use a strong prop rod (like a broom handle)
Never trust the old strut to hold the window once you start.
2. Locate The Strut Mounts
Each strut connects at two points:
- Window end: Small ball joint near the edge of the glass
- Body end: Ball joint attached to the Jeep frame
You’ll see a metal clip or small nut at each end.
3. Remove The Old Struts
- Use a flathead screwdriver to gently pry up the metal retaining clip at each end of the strut.
- Slide the strut off the ball joint. Sometimes, you’ll need to wiggle it.
- If there’s a nut, loosen and remove it with your socket or wrench.
Remove one strut at a time. Keep the window supported throughout.
4. Install The New Struts
- Line up the new strut with the ball joints. Make sure the fat end (cylinder) attaches to the body and the thin end (rod) to the glass.
- Press the socket onto the ball joint until it snaps in place.
- If your struts use nuts, tighten them firmly but don’t over-torque.
Repeat for the second strut.
5. Test The Window
- Carefully remove your prop rod or have your helper let go.
- Open and close the window several times.
- Listen for clicks or binding. The window should move smoothly and stay up on its own.
Extra tip: If the window feels stiff, apply a small amount of silicone spray to the ball joints.
Common Mistakes To Avoid
Even simple jobs can go wrong. Watch out for these rookie errors:
- Not supporting the glass. The window can fall, causing injury or breaking the glass.
- Mixing up strut direction. Most struts have arrows or labels. Install them in the correct orientation.
- Forcing the clips. Metal clips can bend or break if pried too hard. Be gentle.
- Using cheap struts. Poor quality parts wear out fast and may not hold the window safely.
- Ignoring strange noises. Clicking or scraping means something isn’t seated right.
Here’s a quick look at how new and old struts perform:
| Condition | Window Holds Up? | Effort to Lift | Drop Speed |
|---|---|---|---|
| New Struts | Yes | Light | Slow & Safe |
| Worn Struts | No | Heavy | Fast & Dangerous |
When To See A Professional
Most people can do this job at home. However, call a mechanic if:
- A mount is rusted or broken
- The window glass is cracked or loose
- You feel unsure about any step
Damage around the glass or frame can mean bigger problems. Professional help will keep things safe.

Frequently Asked Questions
How Long Do Jeep Liberty Rear Window Struts Last?
Most struts last 5–7 years depending on climate and use. Extreme heat or frequent use can shorten their life.
Can I Replace The Struts Myself Without Special Tools?
Yes, you only need basic hand tools like a screwdriver and wrench. It’s a straightforward DIY job.
Do I Need To Replace Both Struts At The Same Time?
It’s strongly recommended. If one is weak, the other is likely worn too. Replacing both gives balanced support.
Are All Jeep Liberty Rear Window Struts The Same?
No, there are slight differences between model years. Always check fitment before buying.
What If My Rear Window Still Falls After Installing New Struts?
Check that the struts are installed in the right direction and fully snapped onto the ball joints. If the problem continues, the window hinges or mounts may be damaged.
