Is Your Explorer's Back Glass a Hazard?
If you're propping the rear window of your Explorer open with a stick or your hand, it's time for new back glass lift supports. These parts are designed to fail over time as the gas pressure inside them slowly leaks out. This is a normal wear-and-tear item. The most common symptom is the glass not staying up on its own, especially in colder weather when the gas pressure is naturally lower. You might also notice the glass is harder to lift or that it slams shut unexpectedly. This is not just annoying; it's a safety risk for anyone using the cargo area.
Known Issues for 1991-2001 Ford Explorer
For this generation of Explorer, failing back glass lift supports are a common maintenance issue due to age. There are no major recalls or technical service bulletins (TSBs) from the National Highway Traffic Safety Administration (NHTSA) specifically for the back glass lift supports on these models. Problems with the rear window area on these trucks are more commonly related to the hinges that hold the glass to the roof, which can cause rattling or alignment problems. However, the lift supports themselves are a straightforward wear item.
Choosing the Right Aftermarket Lift Support
For a simple part like a lift support, aftermarket options provide excellent value compared to expensive OEM parts. The technology is basic, and quality aftermarket brands produce reliable replacements. Here’s a breakdown of the brands available:
- Stabilus: Often an Original Equipment Manufacturer (OEM) for many car brands, including Ford. Choosing Stabilus is the closest you can get to buying the original part without the dealership price tag. They are known for quality and proper fit.
- Sachs / TRW: These brands are part of the same parent company (ZF) as Stabilus. You may even order a Sachs part and receive a TRW-branded one, or vice-versa. Quality is considered comparable to Stabilus, making them a top-tier choice.
- Strong Arm: A very popular and reputable aftermarket brand. They are widely available and considered a reliable, cost-effective alternative to OEM or brands like Stabilus. Some users report they may not last as long as premium brands but offer good performance for the price.
- FCS Struts: Generally considered a budget-friendly option. For a non-critical part like a lift support, they can be a viable choice if cost is the primary concern. However, for parts that affect ride quality, like suspension struts, reviews are more mixed.

Installation: A 10-Minute DIY Job
Replacing the back glass lift supports is one of the easiest repairs you can do on your Explorer. You only need a small flathead screwdriver. Have a friend hold the glass open or use a prop rod for safety. Use the screwdriver to pry the small metal clips on the old supports and pop them off the ball studs on the glass and body. The new supports simply snap into place with firm pressure.
Frequently Asked Questions
Can I just replace the one lift support that failed?
No, you should always replace them in pairs. A new support is much stronger than the remaining old one. This imbalance will cause the new part to fail quickly and can put stress on the glass and hinges.
Why do my new lift supports seem too stiff?
New lift supports are fully charged and cannot be compressed by hand off the vehicle. This is by design. Once installed, the weight and leverage of the rear glass will allow them to operate correctly. It might take more effort to close the glass initially, but this is a sign that they are working properly.
Do these supports also work for the main liftgate?
No, the back glass and the main liftgate use different lift supports. They have different lengths and pressure ratings. Make sure you are ordering the specific supports for the back glass (window) and not the entire tailgate.
My glass still rattles after replacing the supports. What's wrong?
If the glass itself is loose or rattles, the problem is likely the upper hinges, not the lift supports. This is a very common issue on 1991-2001 Explorers where the metal hinges wear out or the mounting bolts come loose. Check that the hinge bolts are tight.
