Every repair here starts with a **documented module map**. ## What does modular upfit van repair include? Modular upfit van repair covers the mounting system rather than the furniture: floor track anchors that have pulled through, wall rail points with stripped threads, corrosion where aluminum modules sit against steel, and full removal and reinstall for body work. Rancho Santa Margarita fleets have this done in shop at Yorba Linda. - L track and airline track anchors need backing, not longer bolts - Reused holes at the B pillar are where rail loads go wrong - Aluminum against bare steel corrodes without an isolation layer - Reinstall without a module map is guesswork, so we photograph first ### Key facts | Item | Value | | --- | --- | | Systems serviced | Sortimo, bott vario, Ranger Design, Modul-System (Floor track, wall rail and freestanding module types) | | Body rate | $210 per hour (Removal and reinstall is quoted as its own line) | | Module R and I | $750 to $7,500+ (5 to 35 hours depending on module count and condition) | | Lease return | $1,200 to $15,000+ (De-install, hole repair, corrosion treatment and refinish) | | Written estimate | $150 (Credited in full against an authorized repair) | The selling point of a modular interior is that it comes out. A fleet can pull a plumbing configuration on Friday, drop in a signal maintenance configuration on Monday, and put the same van on a different contract. That flexibility is real and it is worth the money. It also means every mounting point in the van gets used, unused, reused and used again, and mounting points do not enjoy that. So the repairs on these vans are rarely about the cabinets. They are about the small pieces of metal that hold the cabinets: a floor track anchor that has begun pulling through the pan, a rail thread at the B pillar that has been stripped by its third reconfiguration, a strip of bare steel behind an aluminum module that has been quietly corroding since the second contract. ## What counts as a modular van, and what does not Sortimo, bott, Ranger Design and Modul-System all build the same idea in different metal: modules that land on a floor track or hang from a wall rail, held with captive fasteners and removable in an afternoon. That is a modular van. A van with plywood shelves screwed to the ribs is a fixed upfit, and it is a different repair conversation because the shelving is not going anywhere. Fleets choose modular for reassignment. The van outlives the contract, the interior gets re-specified, and the same shell serves three trades over eight years. What nobody plans for is that the mounting points age faster than the van does, because they are the only parts being taken apart and put back together repeatedly. - Floor track and airline track: anchor loads go into the pan - Wall rail systems: loads go into the pillars and the ribs - Freestanding modules strapped to D rings: loads go into the floor plate - Fixed plywood shelving: not modular, and usually not properly backed either ## Track anchors and the crescent tear in the pan Look under the plywood in a van that has been reconfigured a few times and you will find the same failure in the same shape. Each track bolt passes through the floor into a thin pan, and the load during a hard stop is shear followed by tension on that single point. The hole ovalizes, the anchor begins to rock, and a small crescent tear opens on the underside of the pan. Backing plates are the answer and they need to be large enough to matter. We fit plates that span two floor ribs, use flanged hardware, and reseal the underside so the new penetration is not a corrosion start point. Adding a longer bolt in the same hole is the version that comes back. ## The third reconfiguration is where rails fail Rivnuts at the pillars are consumable and nobody treats them that way. The first install torques them correctly. The second install finds the threads a little tired. By the third, an installer under time pressure leans on the wrench, the rivnut spins in its hole and the rail is now held by whatever else is nearby. The module load quietly redistributes to fewer points than the design intended. Our repair replaces the anchor style, not just the anchor. Where a rivnut has failed we set a weld nut with a spreading plate behind the pillar face, which stops that position from being consumable at all. It takes longer once and never comes back. 1. Remove the rail run and thread check every position 2. Replace failed rivnuts with backed weld nuts where access allows 3. Reinstate corrosion coating on any drilled or welded area 4. Reinstall to the system manufacturer torque, recorded on the invoice ## The stripe of rust behind every module back Pull an aluminum module out of a van that has been in service six or seven years and there is often a stripe of corrosion on the wall exactly as tall as the module. Two things caused it: moisture trapped at a hard contact face with nowhere to dry, and dissimilar metals in contact accelerating what the moisture began. It is not a leak, and the shape tells you so immediately. The prevention is trivial and almost never done at build time: an isolation layer or a standoff at the contact face. We treat and recoat the affected area, then add that layer during reinstall. On a fleet with a dozen identical vans, this is a finding worth acting on across all of them rather than one at a time. > **note:** If a modular interior has never been out of a van older than six years, plan on finding contact corrosion behind at least one module. Better to schedule that than to discover it during a lease inspection. ## The module map, and why we photograph before we unbolt Removing an upfit is easy. Putting it back exactly as it was is not, and the difference is documentation. Before anything comes out we photograph each wall from three positions, record which track positions each module occupies, and bag hardware per module rather than in one bucket. Then the modules leave the van in order and get staged in that order on the floor. This is also how the billing stays honest. Removal and reinstall is access work, not repair work, and it belongs on its own estimate line with the hours each way. An adjuster who can see the module count and the hours approves it. An adjuster looking at a lump sum labeled upfit asks questions nobody can answer. ## Handing a van back without paying for holes Every modular van eventually goes back to a lessor with the mounting holes still in it, and those holes are chargeable at inspection along with any corrosion that started in them. A long wheelbase van with a full rail system and a floor track grid can carry sixty or more penetrations. The lessor will find them all. Doing this properly means welding or plugging each hole, treating the surrounding metal, and refinishing the affected areas so the interior reads as a cargo van again. It is a genuine job with genuine hours, and fleets that budget for it at lease signing rather than three weeks before turn in are the ones who are not surprised by the number. ## What this work costs and how we sequence it Everything here bills at the body rate of $210 per hour, with body supplies at $5 per body hour, and jobs past $2,000 take a fifty percent deposit at authorization. A written estimate is $150 and credits in full against an authorized repair. Module removal and reinstall is quoted separately from the repair underneath it so the two are legible on their own. For a fleet, the sensible sequence is to combine work: if the interior has to come out for a body repair, that is also the moment to fix track anchors, treat contact corrosion and replace tired rivnuts. Doing those separately means paying the removal hours three times. All of it happens in shop at Yorba Linda, since this is not a mobile service and a module map is not something anyone should build in a parking lot. ## Questions and answers ### Why are the floor track anchors lifting in our upfit van? Each track bolt carries shear and then tension on one small point in a thin floor pan, and a loaded module during a hard stop is enough to ovalize the hole. The anchor then rocks and a crescent tear opens underneath. The repair is backing plates spanning two floor ribs, flanged hardware and resealing the underside. ### An installer stripped a rail anchor at the pillar. Can that be fixed? Yes, and we change the anchor style rather than replacing like for like. Where access allows we fit a weld nut with a spreading plate behind the pillar face, then restore corrosion coating around it. That position stops being consumable, which matters on a van that will be reconfigured again in two years. ### What is the stripe of rust the exact height of my shelving? Contact corrosion. An aluminum module pressed against painted steel traps moisture at the contact face and the dissimilar metals accelerate it. The shape gives it away immediately, because a leak would not follow the module outline. We treat and recoat the area, then add an isolation layer or standoff during reinstall. ### Should upfit removal appear as its own line on an estimate? Yes. It is access work rather than repair work, and separating it is what gets it approved. We list module count, rail runs and hours each way, so an adjuster can see what they are paying for. A lump sum labeled upfit invites questions that nobody can answer without the documentation we already took. ### How do we hand a modular van back at lease end without penalties? Plan for the holes. A long wheelbase van with a full rail system and floor track grid can carry sixty penetrations, and lessors charge for unrepaired holes plus any corrosion in them. We weld or plug each one, treat the surrounding metal and refinish so the interior presents as a cargo van again. ### Is it cheaper to combine upfit work with a body repair? Considerably, because the removal hours only get paid once. If the interior is coming out for a panel repair, that is the moment to fix track anchors, replace tired rivnuts and treat contact corrosion behind the modules. Splitting those into three visits means paying for removal and reinstall three separate times. --- Source: [OCRV Center](https://ocrv.me/vehicles/vans/modular-van-repair/). Last verified 2026-07-29.
