We work the body to chassis joint, fiberglass caps, entrance door frames, luggage bay doors, roof shrouds, bonded window leaks, paint and livery. Chassis mechanical work stays with your dealer. ## Common damage - Crack opening along the joint where the body shell meets the van cowl - Fiberglass front cap seam splitting where it laps onto the cab roof line - Rear cap cracked at the corner radius and around the taillight cutouts - Entrance door frame twisted so the door catches at the top corner - Step well tread structure soft and the lower door post corroding behind it - Luggage bay door sagging on worn hinges and missing the latch striker - Roof air conditioner shroud cracked and the roof penetration leaking at the flange - Water tracking down an interior wall from a bonded side window frame - Rear ladder and roof rack mounting torn loose from thin roof structure - Rear corner and bumper damage from backing at a hotel porte cochere ## The cutaway joint: where a shuttle body meets an E-450 or 4500 cowl A cutaway shuttle is two vehicles bolted together. The front is a factory van cab and chassis, usually a Ford E-450, a Ford Transit cutaway or a Chevrolet 4500. Behind the cowl sits a body built by a completely different manufacturer: El Dorado, Turtle Top, Glaval, StarTrans and others. The seam where those two meet is the single most informative place to look on any used shuttle, because it tells you how the vehicle has been driven and how well the body was mounted in the first place. The two structures move at different rates. The chassis frame twists, the cab shell moves on its mounts, and the body shell behind it is a much stiffer box. Everything that motion produces concentrates at the cowl joint. It shows as a hairline opening in the sealant, then a crack in the transition fairing, then daylight or water, and eventually a fatigue crack in the panel or the mounting bracket. Owners often report it as a rattle or a draft long before they see the crack. The repair is not a bead of sealant. We open the joint, look at the mounting brackets and the body sill where they land on the chassis rails, repair or replace fasteners and brackets that have elongated their holes, and check whether anyone has drilled the frame rail flange to mount something. Then the transition structure gets rebuilt, the joint gets a proper sealing detail with a joint that can move, and the fairing goes back on. Done that way it stays closed. Sealed over without addressing the mounting, it reopens in a year. - Body to chassis mounting brackets and fasteners inspected before the joint is closed - Elongated mounting holes rebuilt rather than fitted with a larger fastener - Frame rail flange drilling repaired and the mounting relocated to the web - Transition structure rebuilt so the sealed joint can still move - Interior trim at the cowl removed and refitted so the repair is checked from both sides ## Fiberglass front and rear cap seam cracking on a shuttle body Shuttle bodies use fiberglass moldings at both ends, and the caps are bonded and bolted to a steel or aluminum body cage. Because the cap is a single stiff shell attached to a frame that flexes, cracks appear at the transitions rather than in the middle of a panel. On the front, the crack usually runs along the seam where the cap laps onto the cab roof line, right where the two vehicles disagree about how much to move. On the rear, cracks radiate from the corner radius and from the taillight cutouts. Cosmetic patching over those cracks is why so many used shuttles show the same crack twice. A crack in a bonded cap seam is a load path problem. We open the area, find out whether the bond line has released or the substrate behind it has moved, drill the crack tip, grind out to a V, and laminate structural mat and resin on both faces where access allows. Where the bond line itself has failed, the cap gets re bonded with a structural adhesive under clamp pressure rather than being drawn down with more fasteners. Fastener strategy matters just as much on the rebuild. Adding fasteners to pull a cracked seam tight is the most common bad repair we see on cutaway shuttles, because it turns a distributed bond into a row of stress concentrations and the cap cracks between them. The correct approach spreads load: rebuilt bonding surface, backing where a mechanical fastener is genuinely needed, and a fairing detail that lets the two structures move slightly. Then the surface is faired, primed with a system compatible with the substrate, and refinished. ## Entrance door frames, step wells and luggage bay door alignment The entrance door on a shuttle cycles constantly and the frame around it takes every one of those cycles. On a hotel or airport unit running all day, the first symptom is a door that catches at the top corner or one that needs a shove at the bottom. Operators adjust the hardware, which works for a few weeks, and then the door binds again. The reason is that the opening is no longer square, either from a corner hit or from years of the body flexing around a doorway that sits in the middle of the side wall. We measure the opening diagonally and check the door post and header for deflection before touching hinges or strikers. Where the post has moved, it gets straightened or sectioned with new material and the header reset. The step well underneath is inspected at the same time, because the step structure and the lower door post are effectively one assembly. Water sits in a step well, works under the tread covering, softens the structure below, and then the post loses its footing and the door geometry drifts. Fixing one without the other is a temporary result. Luggage bay doors on airport and hotel shuttles have their own pattern. They are wide, they are heavy when loaded against, and they hang on hinges mounted into a bay frame that was built light to save weight. Hinges wear, the door sags at the outboard end, the latch stops finding its striker, and drivers start slamming it. We rebuild the hinge mounting into reinforced structure, straighten or replace the door frame, reset the striker to a corrected opening, and repair the bay floor and seal so the compartment stays dry. - Entrance door opening measured diagonally before hardware is adjusted - Door post straightened or sectioned and the header reset to square - Step well structure repaired along with the lower door post as one assembly - Luggage bay hinge mounting rebuilt into reinforced frame material - Bay door striker reset to a corrected opening and the compartment seal replaced ## Roof air conditioner shrouds, rear ladders and roof rack mounting The roof of a shuttle is where deferred maintenance hides. The air conditioner shroud is a large fiberglass or plastic molding sitting in the airstream, and it cracks at the mounting feet from vibration and at the leading radius from wind load plus the occasional branch. Once it cracks, water gets to the flange around the roof penetration, and that flange is holding back everything above the passenger compartment. The interior symptom is a stain on the headliner near the unit, which owners frequently blame on the air conditioner itself. We repair or replace the shroud, then deal with the part that actually matters: the penetration. The roof opening gets inspected for corrosion or delamination around its edge, the flange is rebuilt or reinforced where the material is gone, and the sealing detail is redone properly with the right materials for that substrate. The air conditioner unit, its refrigerant circuit and its controls are not our work and go back to your equipment provider. Mounting, opening structure and sealing are ours. Rear ladders and roof racks tear loose for the same reason on nearly every shuttle we see: they were mounted into thin roof or rear panel material with no backing. Every time someone climbs the ladder, the fasteners work, and eventually they pull through and take a piece of panel with them. We rebuild the panel, install backing plates that spread the load into the body cage rather than the skin, refit the ladder or rack to that structure, and seal every fastener penetration. Where a customer wants a rack that the original body never had, we fabricate the mounting into the cage in shop. ## Bonded window frame leaks and where the water actually goes A shuttle owner almost never reports a window leak as a window leak. They report a wet floor near the wheel arch, a musty smell, a stained wall panel, or a seat frame that has started to rust. Water entering at a bonded side window frame does not fall straight down. It runs inside the wall cavity, follows a wire loom or a stiffener, and comes out somewhere well away from where it got in, which is why chasing the stain instead of the entry point wastes a lot of money. So the first job is finding the actual entry. That means water testing the suspect area methodically from the bottom up, with interior panels off, so we can see where it arrives rather than guessing. Bonded windows fail at the urethane bond line, at a corner where the frame has been flexed, or at a mounting screw that someone added into the frame at some point. On sliding units, the drain slots in the lower track block with dust and the track fills instead of draining, which soaks the wall from a window that is otherwise perfectly sealed. Rebuilding a bonded window is substrate work before it is glass work. We cut the unit out, clean the opening back, repair corrosion or delaminated material in the flange, prime the surface correctly, and set the window in fresh urethane with proper spacing and cure conditions. Then the interior side gets addressed: wall panel replacement where it has swelled, insulation replacement where it stayed wet, and floor repair if the water sat long enough to reach the subfloor. The interior repair is the part owners tend to skip and the part that determines whether the smell comes back. - Water testing from the bottom up with interior panels off to find the real entry - Sliding window track drains cleared and rebuilt where they have blocked - Bonded glass cut out, flange corrosion repaired, opening primed and reset in fresh urethane - Wet insulation and swollen wall panels replaced rather than dried in place - Subfloor checked and repaired where water has been sitting for a season or more ## Hotel, church and airport livery, and what goes back to your maintenance provider Shuttles are rolling signage for a property, so the finish work carries more weight than it does on a delivery vehicle. A hotel shuttle in property colors with correct lettering, a church bus with its name and city, an airport parking operator with a phone number and a logo on both sides: all of it has specified placement and all of it has to come back exactly where it was. We measure and photograph placement before removal, refinish, then reinstall or reorder to those measurements rather than eyeballing it against a photo. Color work on a cutaway has a complication. The van cab, the fiberglass caps and the body side panels are three different substrates that were painted at two different plants, and after several years of Southern California sun they have not faded at the same rate. Matching a repaired rear cap to a body side that has drifted means spraying out and verifying against the actual vehicle in shop light and daylight, then blending across panels. On a shuttle that has been repainted before, we also check what is underneath, because an unknown previous coating dictates the primer system we can use. The boundary at the end is simple. Engine, transmission, drivetrain and brake work on the chassis stays with your Ford or Chevrolet dealer or your fleet maintenance provider, and we do not perform any service certification. The air conditioning unit, the door actuator and any lift equipment belong with their suppliers. Everything structural, everything fiberglass, all glass, all mounting and all finish work is ours, and it is all performed in shop at Yorba Linda. We do not offer mobile service. Shop hours are Monday to Friday 8:00 AM to 5:00 PM and Saturday 9:30 AM to 3:00 PM, and the number is (949) 799-3387. ## Frequently asked questions ### There is a crack opening where the shuttle body meets the van cab. Should we worry? It is worth looking at properly, yes. That joint is where a flexing chassis meets a stiff body box, so any opening there is telling you something about the mounting. We open it up, check the brackets and body sill where they land on the chassis rails, repair elongated fastener holes and any drilling in the rail flange, then rebuild the transition structure with a sealing detail that still allows movement. Sealant alone over an unaddressed mounting problem reopens within about a year. ### Our shuttle smells musty and the wall panel is stained, but we never see water coming in. Why? Because water entering at a bonded window runs inside the wall cavity and follows a stiffener or a wire loom before it appears. The stain is downstream of the leak, sometimes by several feet. We water test from the bottom up with the interior panels off so we can watch where it actually arrives, fix the entry point, then replace the wet insulation and swollen panels. Drying it in place is what makes the smell come back the next rainy week. ### The luggage bay door on our airport shuttle will not latch anymore. Is the door bent? Sometimes, but more often the hinges are worn and the bay frame around them has given up. The door sags at the outboard end, the latch stops reaching its striker, and drivers start slamming it, which accelerates everything. We rebuild the hinge mounting into reinforced frame material, straighten or replace the door frame, reset the striker to the corrected opening, and replace the compartment seal. Then the bay floor gets checked, because a bay that has been open to weather usually has damage underneath. ### Can you repaint a hotel shuttle in our property colors and put the lettering back? Yes, and the placement is the part we take seriously. We measure and photograph all lettering, logos and stripe positions before removal, refinish, then reinstall or reorder graphics to those recorded measurements. On a cutaway, matching also means dealing with three substrates that have aged differently: the van cab, the fiberglass caps and the body sides. We spray out and verify against your actual vehicle in shop light and daylight before anything is shot. ### Do you do any chassis work while our shuttle is in the shop? No. Engine, transmission, drivetrain and brake work on an E-450, a Transit or a 4500 chassis stays with your dealer or fleet maintenance provider, and we do not perform service certification of any kind. Air conditioning units, door actuators and lift equipment go back to their own suppliers. We take the body, the fiberglass, the glass, all structure and mounting, and the paint. Many operators schedule mechanical service right before or after their body repair so the shuttle is out of service once. --- OCRV Center, 23281 La Palma Ave, Yorba Linda, CA 92887.
