The 5th Generation Subaru Forester: Restoring Rear Visibility and Security
The 2019-2024 Subaru Forester is celebrated by crossover enthusiasts for its exceptional outward visibility, expansive cargo capacity, and legendary symmetrical all-wheel drive. Whether you are navigating the dense urban streets of the Greater Toronto Area or loading up gear for a weekend adventure in the Ontario wilderness, the large back glass on your Forester's liftgate plays a vital role in your driving experience. It provides the driver with an unobstructed rearward view, houses the crucial rear window defroster, and seals your cabin against harsh Canadian weather. However, unlike the laminated front windshield, this rear window is manufactured from tempered safety glass. When it sustains a heavy impact from shifting cargo, a rear-end collision, or extreme temperature drops, it does not just crack—it violently shatters into thousands of granular pieces, leaving your vehicle exposed and vulnerable.
Driving with a shattered rear window is not only a severe safety hazard but also leaves your Forester's interior exposed to rain, snow, and theft. Because tempered glass completely disintegrates upon impact, replacing a back window is vastly different from a standard windshield repair. It requires a meticulous cleanup process, structural panel removal, and precise urethane bonding. As a Master Technician at AlexWindshield, I have designed this comprehensive guide to explain exactly how we execute a flawless, factory-standard back glass replacement for the 2019-2024 Subaru Forester.

We do not just replace the glass; we completely restore the safety, security, and cleanliness of your Subaru Forester.
Step-by-Step Back Glass Replacement Process for the 2019-2024 Subaru Forester
Replacing the liftgate glass on a late-model Subaru Forester requires specialized auto glass tools, in-depth knowledge of Subaru's liftgate anatomy, and an obsessive attention to detail. Below is our Master Technician A-to-Z process for a flawless back glass installation.
Step 1: Complete Vehicle Assessment and Interior Protection
Before any tools are utilized, we perform a thorough pre-inspection of the Forester's liftgate. We check for any structural damage to the rear hatch frame, ensure the rear wiper motor is still functional, and assess the spread of the shattered glass. Once assessed, our absolute priority is protecting your vehicle's interior. We lay down heavy-duty protective drop cloths over the rear cargo floor, bumper, and folded-down rear seats. We also tape off the exterior painted surfaces surrounding the rear window opening to prevent any accidental scratches during the extraction process.
Step 2: Liftgate Panel Removal and Extensive Glass Clean-Up
When the tempered back glass of a Subaru Forester breaks, the majority of the shards fall directly into the inner cavity of the rear liftgate. If these shards are not entirely removed, they will slide and rattle inside the metal hatch every time you accelerate, brake, or open the trunk. To prevent this, we meticulously unclip and remove the interior plastic trim panels from the inside of the liftgate.
With the inner mechanics exposed, we utilize high-powered, industrial shop vacuums fitted with specialized narrow nozzles to extract every single piece of broken glass from the vehicle's interior, cargo area, and deep within the liftgate shell. Vacuuming all broken glass shards is a mandatory, non-negotiable step in our process. We also safely disconnect the electrical harness for the rear wiper motor and carefully unbolt the wiper arm assembly, as it passes directly through the lower section of the Forester's back glass.
Step 3: Extracting the Remaining Back Glass and Old Urethane
Even though the center of the glass has shattered, the outer perimeter of the glass is still heavily bonded to the vehicle's pinch weld by the factory polyurethane adhesive. Using professional-grade cold knives, specialized wire cutting systems, and power extractors, our technicians carefully slice through the original urethane bead. We extract the remaining glass ring without bending or damaging the metal liftgate frame. Once the glass ring is removed, we perform the "close cut." This involves using a razor-sharp scraper to trim the old urethane bead down to a uniform thickness of 1-2 millimeters, creating a stable, flat base for the new adhesive to bond with.
Step 4: Surface Cleaning and Primer Application
A successful auto glass installation is entirely dependent on chemical bonding and surface preparation. We vigorously clean the freshly trimmed pinch weld using specialized lint-free wipes and automotive-grade surface cleaners to remove dirt, grease, and moisture. If our tools accidentally caused any micro-scratches to the paint on the pinch weld during the removal process, we immediately treat those areas with a specialized bare-metal primer. This prevents future rust formation, which is a common cause of delayed glass leaks in the harsh, salt-heavy winters of the GTA.
Step 5: Preparing the New Back Glass and Defroster Grid
We source only premium, OEM-equivalent (Original Equipment Equivalent) back glass specifically manufactured for the 2019-2024 Subaru Forester. We place the new glass on a padded glass stand and wash it thoroughly with an ammonia-free glass cleaner. Next, we apply a specialized glass prep and chemical frit primer to the black painted band (the frit) around the inner edge of the glass. This primer alters the molecular structure of the glass surface, allowing the new urethane adhesive to fuse permanently. During this step, we also inspect and clean the copper connection terminals for the built-in thermal defroster grid.
Step 6: Precision Application of High-Quality Urethane Adhesive
Using a battery-operated, high-thrust caulking gun, our technicians apply a continuous, precise V-bead of premium, fast-curing automotive urethane directly onto the prepared pinch weld (or the glass, depending on the specific liftgate geometry). We use industry-leading adhesives that meet all Federal Motor Vehicle Safety Standards (FMVSS). The triangular V-bead ensures that when the glass is compressed, the adhesive spreads evenly without air pockets, creating a watertight, structurally sound seal.
Step 7: Installation of the New Subaru Forester Back Glass
Because the Subaru Forester's rear glass is large and uniquely contoured, precision handling is required. Utilizing heavy-duty suction cups, our technicians carefully lift the newly primed glass, aligning it perfectly with the vehicle's roofline, side pillars, and lower hatch gap. We gently set the glass into the fresh urethane bead and apply even, controlled pressure around the perimeter to ensure maximum contact and adhesive spread. We use specialized retention tape to temporarily hold the glass in its exact factory position while the rapid-curing urethane begins to flash off and harden.
Step 8: Reassembly, Reconnection, and Final Vacuuming
Once the glass is locked into place, we begin the reassembly process. We carefully reinstall the rear wiper motor assembly through the dedicated glass port, ensuring the rubber grommets are perfectly sealed against weather intrusion. We then re-attach the wiper arm and torque the retaining nut to factory specifications. Next, we reconnect the electrical wiring harnesses to the defrost grid terminals, testing the circuitry to ensure your rear defogger will work flawlessly during the cold Ontario winters.
Finally, we reinstall all the interior liftgate trim panels, ensuring every factory clip snaps securely back into place. We perform one last, exhaustive interior vacuum of the cargo area and rear seats to guarantee that absolutely no microscopic glass dust remains, returning your Forester to you in pristine condition.
