Matching the Cab Configuration and Glass Part Numbers
Identifying the exact cab configuration is the first requirement before replacing quarter glass on this truck, because only the two-door Regular Cab utilizes fixed rear quarter panels. Ford engineered this cab with unique mini-access doors situated behind the front doors, whereas SuperCab variants feature rear suicide doors with roll-down glass, and SuperCrew models rely entirely on standard four-door roll-down windows. When sourcing aftermarket glass for the Regular Cab, the driver-side panel references NAGS number DQ10469, while the passenger side corresponds to DQ10470. These stationary tempered glass panels are offered in two tint levels across trims like the XL, STX, and XLT: a solar green tint (suffix GTN) or factory dark gray privacy tint (suffix GTY).
Pre-Installation Checks on the F-150 Quarter Window
Before installing the replacement panel into the cab frame, I inspect the glass edge profile and the integrated hardware against the truck's stamped steel aperture. The glass features single-pane tempered safety construction bordered by a black ceramic frit band that conceals the inner pinchweld and mounting hardware. Inspect the following points on the replacement piece:
- Perimeter stud condition: The quarter glass assembly relies on threaded studs that pass through the steel pillar frame and accept Ford retaining nuts (-N621901-S2). I check that these studs are firmly anchored into the encapsulation and not cross-threaded or bent.
- Ceramic frit integrity: Ensure the interior-facing ceramic enamel band is solid without pinholes or thin patches, which prevents sunlight from degrading the adhesive bed underneath.
- Tint level consistency: XL and STX base models typically left the factory with standard solar green tint, while XLT and appearance packages usually carried dark gray privacy glass. Holding the new panel against the front door drop glass confirms the color tone matches.
- Heritage model distinction: The 2004 Heritage edition uses the older tenth-generation body style with DQ09117 or DQ09118 glass shapes; these older units will not fit the revised 2004–2008 cab aperture.
Post-Installation Fitment and Interior Trim Alignment
Once the replacement glass is seated into the mini-door pillar assembly, the surrounding trim and water-management areas require close attention. I run my mobile service directly to your driveway or job site anywhere across Toronto and the GTA, so getting the panels weather-tight and correctly aligned on-site is essential before you drive. Inside the cab, the molded plastic upper and lower B/C-pillar corner trim panels must clip back flush over the stud fasteners without binding against the edge of the new glass. If the inner panel presses unevenly against the glass margin, road vibrations can transfer directly into the tempered panel.
On the exterior, verify that the glass sits uniformly between the cab roofline above, the rear cab corner pillar, and the lower beltline molding. The outer surface should align parallel to the front door frame to eliminate high-speed wind whistle along the cab pillar.
Diagnosing Cab Water Leaks Near the Quarter Panel
Water pooling under the rear storage tray or beneath the carpet in the cab corners is a frequent complaint on this truck, but the quarter window seal is not always the source. Ford issued Technical Service Bulletin TSB 04-20-5 to address cab water intrusion caused by degraded gaskets on the center high-mount stop light (CHMSL) above the rear window. Water leaking through the third brake light housing runs down the inner metal roof structure, travels along the cab corners behind the interior plastic trim, and collects on the floor directly below the quarter glass. I always inspect the cab corner sheet metal and brake light area to verify whether damp carpet stems from a deteriorated quarter window perimeter bead or an overhead brake light leak.
Can I install a SuperCab rear window into a Regular Cab?
No. The SuperCab uses functional roll-down windows mounted within complete rear suicide doors. The Regular Cab uses dedicated stationary quarter panels designed specifically for its mini-access cab structure.
Does this quarter glass include embedded heating wires or antennas?
No. The stationary quarter glass on the 2004–2008 Regular Cab is purely passive tempered glass without rear defroster grids, integrated radio antenna elements, or wiring harnesses.
