# High Cube Van Repair for Eastvale, California > Box panel, corner post, roll up door and roof repair for cube vans running delivery routes from Eastvale. Source: https://ocrv.info/vehicles/vans-and-camper-vans/high-cube-van A high cube van mounts a tall cargo box on a van or light truck cutaway chassis, often with a fiberglass reinforced panel body and a rear roll up door. Repair work covers box panel and corner post damage, translucent roof panels, roll up door and track repair, cab to box gap sealing, rear frame and bumper structure and refinishing. ## Pricing Typical range $1,500 to $40,000+, 10 to 200 hours. A cube van is two structures with different failure modes sharing one set of wheels. The cab is a production vehicle with automotive panels and paint. The box behind it is a purpose built cargo body, typically fiberglass reinforced panel bonded to an aluminum or steel frame, with a translucent roof to light the interior and a roll up door at the back. Repair estimates almost always cover both. The box is where the damage concentrates. Corner posts get struck in alleys and parking structures. The rear frame takes dock impacts. Side panels get scraped by gates and pillars. The translucent roof panel yellows, crazes and eventually cracks, and once it cracks it leaks over whatever is loaded underneath. The roll up door goes off its track, loses spring tension or bends a slat, and then the van cannot be loaded at all. Delivery operators working out of Eastvale industrial space along Hamner Avenue and the I-15 corridor keep these vehicles moving constantly, and box damage rarely stops a route until it does. The Yorba Linda facility handles box panel replacement, corner post repair, roll up door rebuilding, roof panel replacement and refinishing in shop. Scope is body, paint, structural and equipment work. Engine and drivetrain service is not performed. ## Common damage - Struck rear corner posts - Crazed and yellowed translucent roof panels - Bent roll up door slats and tracks - Lost torsion spring tension - Rear frame dock impact damage - Delaminated FRP side panels - Leaks at the cab to box transition ## Box panels, corner posts and rear frame Fiberglass reinforced panel bodies are built as a stressed skin over extruded frame members. The corner posts are the vertical extrusions at each rear corner, and they tie the roof rail, the side rail and the rear frame together. A strike at that corner deforms the post and opens the joints above and below it, so the damage extends further than the visible dent. Repair replaces the post rather than pulling it, because a straightened extrusion will not hold the joint geometry. Panel repair depends on the construction. Bonded FRP panels can be sectioned and re bonded with structural adhesive where the substrate is intact, using a scarfed joint and a backing member. Where the core is crushed or the panel is delaminated over a large area, replacement of the full panel between frame members is the correct answer. The rear frame, which takes the dock impacts, gets straightened or sectioned with matching extrusion and new fasteners. - Corner post extrusions replaced rather than straightened - Panel joints scarfed and backed rather than surface patched - Full panel replacement where the core is crushed - Rear frame sectioned with matching extrusion - Roof and side rail joint geometry re established ## Roll up doors and the track system A roll up door is a set of hinged slats riding in side tracks, counterbalanced by a torsion spring in the drum at the top. Every part of that assembly wears. Slats bend when something shifts against them in transit, hinges elongate, rollers seize, tracks bend at the bottom where forklift and pallet contact happens, and the spring loses tension until the door is too heavy to lift. Owners usually report it as a door that will not stay up. Repair addresses the assembly as a system. Bent slats get replaced individually where the rest are sound. Tracks get straightened or replaced, particularly at the lower section. Rollers and hinges get replaced as a set so the door runs evenly. The torsion spring gets adjusted or replaced to the correct rating for the door weight, which is a procedure with real hazard and belongs in a shop with the proper tooling rather than being attempted in a yard. ## Roof panels, cab gap and finish The translucent roof panel on a cube body is a consumable. Ultraviolet exposure yellows it, hail crazes it, and thermal cycling opens the bond at the roof rails. Replacement removes the old panel, cleans the bonding surfaces on the rails completely, and sets a new panel with the correct adhesive and bead. Doing this properly requires the body indoors at a controlled temperature, which is one reason it is a shop job rather than a yard job. The gap between the cab and the box is a persistent water path. Most cube vans have a flexible boot or a sealed plate at that transition, and it fails from movement over time. Water then runs down the back of the cab and into the cargo area or the cab floor. Repair rebuilds that transition with a detail that allows movement. Refinishing the box, whether a full repaint or a panel blend, and applying fleet lettering complete the job. - Bonding surfaces cleaned completely before new roof panel - Roof panel set at controlled temperature indoors - Cab to box transition rebuilt to allow movement - Interior lining and scuff band repaired where struck - Fleet lettering reapplied after full cure ## Frequently asked questions ### My roll up door is heavy to lift. Is that the spring? Most likely, though binding in the track produces a similar complaint. A torsion spring that has lost tension makes the door heavy through the entire travel, while a bent track or seized roller makes it heavy at one point. Diagnosis cycles the door and observes where the effort changes. Spring work is done in shop with the correct tooling because of the stored energy involved. ### Can a cracked translucent roof panel be patched? Patching rarely lasts. The panel is under thermal stress across its whole area and a patch creates a stiff spot that concentrates load, so the crack usually reappears beside the repair. Replacement removes the panel, cleans the rail bonding surfaces back to a sound substrate, and bonds a new panel with the correct adhesive at a controlled temperature. ### Is FRP box panel damage repairable or does the panel come out? Both are done, and the deciding factor is the core. Where the skin is damaged but the core is intact, a scarfed and backed section repair bonds in well and refinishes invisibly. Where the core is crushed, water has entered the laminate, or the delamination runs over a wide area, replacing the panel between frame members produces a better result. ### Do you repair the cab and the box in one visit? Yes, and that is normal on these vehicles because a single incident often damages both. Cab panel work follows conventional collision practice with factory paint matching, box work follows cargo body practice, and the refinish plan covers the transition between them. All of it happens in shop at the Yorba Linda facility rather than being split between two vendors. --- OCRV Center. 23281 La Palma Ave, Yorba Linda, CA 92887. (949) 799-3387. info@ocrvcenter.com.
