This work covers walk in and furniture bodies: cracked molded caps, working rivet lines along the belt rail, worn step door jambs and treads, attic and translucent roof leaks, and E track anchors torn out of wall posts. Rancho Santa Margarita operators have it done in shop at Yorba Linda. - The front cap is structural on a walk in, not a cosmetic nose - Black streaks under rivets mean the panel is moving - A step door opens 150 times a day and wears its jamb - Attic leaks on furniture bodies show up over the cab ### Key facts | Item | Value | | --- | --- | | Bodies | Utilimaster Aeromaster and Velocity, Morgan Olson Route Star (On MT45, MT55 and P1000 series walk in chassis) | | Typical length | 18 to 30 feet (GVWR 14,000 to 26,000 lb) | | Stops per day | 120 to 180 (The cycle count that wears step doors and treads) | | Body rate | $210 per hour (Paint supplies at $55 per paint hour on cap refinishing) | | Cap repair band | $600 to $5,500 (3 to 26 hours depending on crack location and rib involvement) | A walk in van is not a truck with a body on it. The body is the structure, the cab is part of the body, and the driver walks between the two without opening a door. That construction is what makes the vehicle brilliant at 150 stops a day, and it is also why damage here behaves differently than on any other commercial vehicle we handle. There is no separate frame to absorb flex, so flex goes into the skin. Furniture bodies share the construction and add their own problems: a drop frame for a low deck, an attic over the cab for long items, interior E track instead of shelving, and a ramp instead of a gate. The two families sit on one page because the repair techniques are the same, and because the composite cap and the rivet lines are the first thing we look at on either one. ## The body is the vehicle On a conventional truck the frame carries the loads and the body is a passenger. A walk in body is the opposite: the aluminum structure, the riveted skin and the molded caps work together as one unit, and the chassis rails underneath are comparatively light. That is why these bodies are so efficient and why they cannot be repaired with box truck habits. Practically, it means two things. First, flex has to go somewhere, and on a stressed skin body it goes into fasteners. Second, the composite caps are not decoration. They tie the roof, the floor and the door openings together at each end, so a cracked cap is a structural finding and gets treated as one. - Molded front and rear caps: structural, bonded and riveted in - Belt rail rivet lines: the primary load path between skin and post - Drop frame furniture chassis: more flex, more fastener movement - Interior E track: only as strong as what it is fastened through to ## Cracks in the cap change how the doors shut The front cap holds the windshield opening and frames both cab doors, so it is under load every time the body twists. Cracks appear at the windshield corner radius first and at the door frame second, and the driver notices the doors before anyone notices the crack. A door that needs a shove on a walk in van is often reporting a cap problem. Repair means treating the composite properly: abrade the substrate, respect the rib pattern on the back face, use an adhesive system rated for the material and reinforce behind the repair where access allows. Then refinish, which on a solid fleet color over a large curved surface is real paint work rather than a spot repair. ## Reading the black streaks under a rivet Walk past a ten year old step van and look along the belt rail. If there is a short black streak trailing back from a row of rivets, those fasteners are moving in their holes. The streak is aluminum oxide generated by two surfaces rubbing against each other thousands of times a day, and it is the cheapest diagnostic available on this vehicle. What we do about it depends on how far it has gone. Early, the affected rivets get replaced with the correct diameter and the panel is re-secured. Late, the holes have elongated and the panel edge has fretted, so a section is the honest answer. Drilling one size up to catch a loose rivet is the industry's favorite shortcut and it fails within two years. > **warning:** Never oversize a rivet hole to chase a loose fastener on a stressed skin body. Each step up removes material from a panel that is carrying load, and the next failure is bigger than the one you just hid. ## One hundred and fifty stops a day The curb side step door is the highest cycle component on any parcel vehicle. It opens and closes at every stop, the driver steps on the same tread and grabs the same jamb, and the track collects grit at knee height. Over five years the jamb wears through its coating and then its metal, the door drops in its track, and the tread edge rounds off into a genuine slip hazard. We rebuild these as a set: track, rollers, jamb material, tread and the seal. Replacing the tread alone on a worn jamb leaves the door still dropping, and replacing the track without addressing the jamb wear leaves the driver holding a sharp edge. Fleets that schedule this at five years avoid the injury report that otherwise triggers it. 1. Inspect track straightness and roller condition with the door removed 2. Rebuild or replace worn jamb material rather than coating over it 3. Fit new tread with a proper edge and non slip surface 4. Refit, adjust and cycle the door before release ## Attics, granny boxes and where they leak The attic over the cab on a furniture body is where long items go and where water gets in. It is a stepped extension of the roof with two additional transverse joints, and it sits directly over the driver. Cab movement works the sealant at those joints, and translucent panels above the attic craze faster than the main roof because nothing shades them. We water test in stages with the interior visible, which on these bodies is straightforward because you can stand inside. Then we open the joint, clean back to sound material and reseal properly, or replace a crazed panel where it has gone milky. Sealing over a failed joint from outside gives you one dry winter. ## E track, ramps and the low deck problem Furniture bodies restrain tall unstable loads with straps into E track, so the track has to be fastened through to a post rather than into skin. When it is not, a shifting wardrobe box takes track and wall material with it. We remount into posts with spreading plates, and where a customer wants additional tie down positions we add them properly rather than screwing track wherever it is convenient. The ramp and the drop frame bring their own damage. A low deck drags on steep driveways and the ramp hinge takes abuse every load, so rear sill cracking and bent ramp hinges are routine. We repair the sill and check the ramp latch geometry, because a ramp that no longer stows square rattles itself and its hinges apart. ## Fleet color, downtime and what it costs Parcel and moving fleets run solid colors with large logos, which is both easier and harder than metallic work. Easier because a solid is straightforward to match. Harder because a big flat composite cap in a saturated color shows every wave, so cap refinishing goes in the booth with proper preparation rather than being blended in a bay. Body and paint bills at $210 per hour with paint supplies at $55 per paint hour, and a written estimate is $150 credited in full against an authorized repair. A step door rebuild is two to four days. A cracked cap with refinishing is a week to ten days. All of it happens at the Yorba Linda facility, in shop, since this is not a mobile service. ## Questions and answers ### My step van cab doors need a shove. Is that the cap? Often yes. On a walk in body the front cap frames both cab doors and carries the windshield opening, so a crack at the corner radius or the door frame changes how the doors sit. We inspect the cap before adjusting hinges, because adjusting a door on a cracked structural cap moves the problem rather than solving it. ### What are the black streaks trailing from rivets on my step van? Aluminum oxide from two surfaces rubbing. The rivets are moving in their holes, which means the skin and post are no longer working as one. Caught early, the affected rivets get replaced at the correct diameter. Once holes have elongated and the panel edge has fretted, that area needs sectioning instead. ### Is drilling a rivet hole one size larger an acceptable fix? No. Every step up in hole size removes material from a panel that is carrying load on a stressed skin body, so the next failure is larger than the one being hidden. We replace with the correct diameter, and where the hole is already elongated we section the panel rather than chasing it up the fastener chart. ### How often does a parcel van step door need rebuilding? Around the five year mark on a busy route, because that door cycles at every one of 120 to 180 stops a day. We rebuild it as a set: track, rollers, jamb material, tread and seal. Doing one piece at a time leaves the door still dropping or the driver still gripping a worn edge. ### Why does water appear over the cab in a furniture body? The attic is a stepped roof extension with two extra transverse joints, and it sits right above the driver. Cab movement works the sealant there and unshaded translucent panels above it craze early. We water test in stages from inside, then open and reseal the joint properly or replace a crazed panel. ### Our E track tore out with a piece of the wall. Can it be reinstalled? Yes, but not into the same fastening. Track has to land through to a wall post, not into skin, or the next load shift removes it again. We repair the panel, remount the track into posts with spreading plates, and add any extra tie down positions properly while the wall is open. --- Source: [OCRV Center](https://ocrv.me/vehicles/commercial-and-heavy/parcel-and-furniture-delivery-truck-repair/).
