How the 4xe Roof Style Dictates Your Quarter Window Replacement
Because the plug-in hybrid Wrangler is built strictly in the 4-door Unlimited body style, you never have to guess between two-door and four-door dimensions, but you do have to verify the exact roof system fitted over your cargo area. Unlike typical SUVs where rear side glass mounts straight into the welded steel body, this vehicle integrates the rear quarter windows entirely into the removable roof structure above the tub rail.
Your replacement method falls into one of two completely different designs depending on the factory equipment:
- Modular 3-Piece Hardtop: Fixed, stationary quarter windows bonded into the composite shell. The driver side uses Mopar base reference 68291709AC, which superseded the earlier AA and AB revisions.
- Sky One-Touch Power Top: Rigid, quick-release side window assemblies (such as OEM unit 68563659AB) held in by interior latches and alignment pins rather than fixed adhesive.
- Standard Soft Top: Flexible, non-glass vinyl side curtains that slide and zip into place, requiring no auto glass replacement.
| Roof Configuration | Glass Mount Style | Rear Side Glass Construction |
|---|---|---|
| 3-Piece Freedom Top | Urethane bonded to composite hardtop shell | Tempered glass with baked ceramic frit border |
| Sky One-Touch Power Top | Mechanical latching frame with guide pins | Removable structural side panel assembly |
| Sunrider / Soft Top | Zipper and track channel system | Clear or tinted flexible vinyl window |
Bonded Hardtop Shells versus Sky One-Touch Removable Side Glass
If your 4xe has the standard three-piece modular hardtop, the quarter window is fixed directly against the molded sheet molding compound (SMC) fiberglass frame. The glass itself is flat, single-pane tempered safety glass with a wide baked-on ceramic black frit band along the perimeter to shield the adhesive line from direct solar UV degradation. It carries a heavy factory privacy tint matching approximately 20% visible light transmission, blending with the rear swing-gate liftglass.
There are no internal electronics inside the quarter glass itself. Rear defroster grid lines and electrical connections belong solely to the rear liftglass, so replacing this side glass involves no antenna leads or heating elements to disconnect. When I replace bonded hardtop glass, you get a full one-year warranty on the aftermarket glass itself alongside my lifetime guarantee covering the workmanship of the installation.
If you drive a 4xe Sahara, Rubicon, or High Altitude equipped with the Sky One-Touch Power Top, a broken quarter window is an entirely different repair. These side units are complete drop-in modular frames rather than stationary glued panes. They are designed to be manually pulled from the vehicle using interior release handles and stored away in dedicated cargo bags (Mopar part 68297726AD) when driving open-air.
Interior Cargo Accessories and Common Post-Breakage Issues
The JL Unlimited cargo cargo layout on the 4xe features high interior fender wells that house the 17.3 kWh high-voltage lithium-ion traction battery beneath the rear passenger seats. Because the space is tightly configured, many owners bolt interior overland accessories—such as steel cargo molle storage racks or fold-down exterior gullwing access hatches—around the inner perimeter of the hardtop quarter glass openings. If you have interior storage panels or recovery gear bolted directly through the hardtop structural points near the window perimeter, these brackets must be unbolted to give full, clear access to the window opening.
When owners notice moisture near the bottom edge of the hardtop glass, the source is rarely an adhesive failure at the glass itself. In the Wrangler JL platform, water pooling in the rear load floor typically traces back to aged foam seals along the hardtop-to-body tub rail, or misaligned latching pins on Sky One-Touch side panel tracks that fail to seat fully against the weatherstripping.
