Product Information

Full details

This Genuine Monroe Rear Boot Spring Gas Strut (ML5831) is designed for VW Passat Variant (3C5) owners needing a replacement for their rear cargo area lift support. Its primary benefit is restoring smooth, reliable operation to the tailgate, ensuring easier access and closing. A key consideration is that it is sold individually, meaning two may be needed for full functionality. Key features include specific dimensions for a precise fit, a robust construction for durability, and an eject force of 550N for effective lifting.

FAQs

How do I know if I need to replace my rear boot gas struts?

Signs include the tailgate feeling heavy, not staying open on its own, closing unexpectedly, or showing visible signs of damage like leaking fluid or bent components.

Can I replace just one gas strut?

Yes, you can replace a single strut. However, for optimal balance and performance, it is highly recommended to replace both rear boot struts at the same time, as they wear at similar rates.

What tools are needed to install this gas strut?

Typically, basic hand tools such as screwdrivers, socket wrenches, or pry tools might be needed to release mounting clips or unscrew bolts. Safety glasses and a way to support the tailgate are essential.

Is this part compatible with my specific car model?

This strut is designed for the VW Passat Variant (3C5) models constructed from 02/2006 to 11/2009, and from 11/2009 to 11/2010. Please verify your vehicle's exact model and production date.

What does 'sold individually' mean?

It means that each package contains only one gas strut. If your vehicle uses two struts for the rear boot (which is common), you will need to purchase two units.

What is the eject force of this strut?

The eject force is 550 Newtons (N), which is the force required to extend the strut.

What are the main dimensions of the strut?

The strut has a total length of 450mm, a stroke of 180mm, a cylinder bore of 18.5mm, and a standpipe diameter of 8mm.

Troubleshooting

Tailgate does not lift smoothly or stays open.

The gas strut may have lost its pressure. Ensure it is the correct part number for your vehicle and consider replacing it. If replacing only one, ensure the other is also in good condition or replace both simultaneously for balanced support.

Tailgate closes too quickly or slams shut.

This indicates the gas strut has failed and is no longer providing adequate resistance. Replace the faulty strut immediately to prevent damage or injury.

Strut appears damaged or leaking fluid.

Do not attempt to use or repair a damaged gas strut. Replace it immediately with a new, compatible unit.

Cons

  • Sold individually, requiring purchase of two for complete replacement of both struts.

Setup, Compatibility & Care

Compatibility: This strut is specifically designed for the VW Passat Variant (3C5) models produced between February 2006 and November 2009, and again from November 2009 to November 2010. Verify your vehicle's exact model and production date before purchasing. The compatible OE part numbers are 3C9827550 and 3C9827550A.

Setup: Installation typically involves safely supporting the tailgate, removing the old struts (usually by releasing clips or unscrewing mounting points), and attaching the new Monroe strut. It is often recommended to replace both struts at the same time for even lifting. If you are not comfortable with automotive repairs, professional installation is advised.

Care: Gas struts are sealed units and generally require no user maintenance. Avoid exposing them to excessive dirt or corrosive substances. Ensure mounting points are clean and free from rust. Periodically check that the tailgate opens and closes smoothly; any signs of stiffness or drooping may indicate a need for replacement.
