We straighten rear corner posts, rebuild roll up doors and counterbalance springs, repair Maxon, Tommy Gate and Anthony mounting plates, and treat rivet line corrosion. Body, paint and structural only. ## Pain points - A rear corner post goes out of plumb at the dock and the roll up door binds in the track before anyone connects the two. - A pallet jack crushes the bottom door panel and the seal stops touching, so the load gets wet on the next rainy route. - The counterbalance spring loses tension and drivers start slamming a heavy door down, which accelerates every other failure in the assembly. - Lift gate mounting plates crack at the weld toe and the crack is discovered by a driver, not by an inspection. - Nobody in the office knows whether the body is sheet and post aluminum or FRP composite, and the two are priced and repaired completely differently. - Rivet line corrosion works from the inside out, so the panel looks cosmetic right up to the point the post face behind it is pitted. - October through December is when nothing can be off the road, and that is exactly when dock traffic and driver fatigue produce the most damage. - DOT number lettering and livery come off with the damaged panel and the vehicle cannot run correctly lettered until it goes back on. - Deferred body damage accumulates all year and then competes with peak season for the same weeks. ## Dock strikes: bent rear corner posts and roll up doors that bind in the track The rear of a delivery body absorbs more damage than the rest of the vehicle combined, and almost all of it comes from the dock. Backing in at an angle loads the corner post rather than the bumper, the post goes out of plumb, and everything downstream stops working. The door binds partway up. The seal loses contact along one side. The latch will not reach its keeper. Drivers report the door because that is what they touch. The post is what actually failed. Repair order matters more than repair technique here. Straightening or replacing the corner post and squaring the rear frame comes first, before any door component is touched. A track reset against a frame that is still twisted just transfers the problem. Once the opening is square, the door assembly gets rebuilt as a system: track straightened or replaced where forklift contact has pinched it at the bottom, seized rollers replaced, worn panel hinges replaced so the slats stop walking sideways, and a new bottom panel and seal fitted to a threshold that now sits parallel. The counterbalance spring is the component most often ignored and most responsible for repeat damage. As tension drops, the door gets heavy to lift and slams on the way down. Every slam accelerates hinge wear, roller wear and track distortion, and it is also how bottom panels get bent in the first place. We reset or replace the spring assembly as part of the door rebuild rather than treating it as an optional line item. A correctly tensioned door is the difference between a repair that lasts a season and one that lasts years. - Rear corner post and header straightened or replaced before any door work - Rear frame squared and verified, then the track reset against it - Pinched track sections replaced where forklift contact has crushed the bottom - Seized rollers, worn hinges, crushed bottom panels and seals replaced as a set - Counterbalance spring reset or replaced as part of the assembly, not as an extra - ICC bar, bumper and rear sill rebuilt where backing damage reached them ## Lift gate mounting plate cracks on Maxon, Tommy Gate and Anthony gates A lift gate is a structural attachment, not an accessory, and that is the single most useful thing to understand about repairing one. Every cycle of the gate transfers the platform load through the mounting plate into the rear frame rails. Cracks appear in predictable places: at the plate corners where stress concentrates, at the weld toe along the frame rail, and at the gusset where the platform arm loads the structure. Maxon, Tommy Gate and Anthony gates all share this behavior because the physics is the same regardless of brand. The failure is progressive and quiet. A hairline at the weld toe grows a little on every cycle, and the first symptom an operator usually notices is that the platform no longer sits level or that the gate has developed a slight rock under load. By then the crack has usually traveled. This is why a mounting plate inspection belongs on the list whenever a body is in the shop for anything else. It costs almost nothing to look and it is expensive to find out the hard way. The repair is fabrication work. We cut out cracked plate material rather than welding over it, rebuild with correctly specified stock, prepare the frame rail properly before welding, add gusseting where the original design was marginal, and refinish so the repaired area does not become the next corrosion point. Where a fleet keeps having the same crack in the same place across multiple units, the fix is a reinforcement detail applied to all of them, not a repeated repair on each. Hydraulics stay with your equipment supplier. Power units, cylinders, pumps and the electrical control side of a gate are service items outside our scope. Tell the estimator at intake which parts of the job you want us to carry so the boundary is set before the vehicle is apart. - Cracks addressed at plate corners, frame rail weld toes and arm gussets - Cracked material cut out and replaced rather than welded over - Frame rail prepared properly before welding, then refinished against corrosion - Reinforcement details applied fleet wide where the same crack repeats - Hydraulic power units, cylinders and controls left with your gate supplier ## Sheet and post aluminum versus FRP composite: two different repair paths Delivery bodies on West Covina routes come in two constructions and they are not repaired the same way. Sheet and post bodies use aluminum panels riveted to vertical posts. The advantage is that damage stays contained: a single bay can be opened, the skin replaced, and the cost tied to the damaged section rather than the whole side. Morgan, Supreme and Utilimaster all build in this style, and it is why a straight forward side impact on a sheet and post body is often cheaper than it looks. FRP composite bodies bond fiberglass reinforced panels over a plywood or foam core in wide sections. The exterior is smooth with fewer seams, which looks better and cleans easier, but a localized puncture becomes a bonded section repair rather than a panel swap. We cut back to sound laminate, scarf the edges so the new material has bonding area, rebuild the core, and lay in new skin with structural adhesive under clamp pressure. Cure time at temperature is part of the schedule, and it is not compressible. Knowing which construction you have changes the estimate before anyone writes a line. It also changes the fastener conversation. On a sheet and post repair, rivet diameter and grip length have to match the post material and the combined thickness being clamped. A rivet that is too long does not set properly and the joint works loose. A rivet that is too short pulls through. Getting this right is unglamorous and it is the difference between a panel that stays tight and one that starts weeping at the fastener line within a year. - Sheet and post: skin replaced bay by bay with post faces treated before reskinning - FRP composite: scarfed edges, rebuilt core, structural adhesive under clamp pressure - Rivet diameter and grip length matched to post material and clamped thickness - Interior scuff band and liner reinstalled where a repair reaches through the wall - Insulated liner delamination on refrigerated bodies handled as its own repair line - Roof panel and drip rail repair after a low clearance strike on either construction ## Rivet line corrosion that works from the inside out on a delivery body Rivet line corrosion is the slow failure that catches logistics operators off guard, because it presents backward. Water tracks behind the panel, sits at the fastener, and attacks the post face from the inside. What shows on the outside is a chalky bloom and a stain streak running down from each rivet head, long before anything feels loose or looks structurally wrong. By the time a driver mentions it, the substrate has usually already pitted. The consequence for repair planning is important. Replacing the panel alone puts a new skin over a bad post, and the same streaks return within a season because the source was never addressed. A correct repair treats or replaces the post material behind the panel, which is more labor and less visible than the skin work. This is the single most common place where a cheap quote and an honest quote diverge on a delivery body. Prevention is mostly about sealing and water management. Seams at the roof to sidewall junction, the drip rail, the front corner posts and any equipment mounted through the wall are where water gets in. Whenever a body is open for other work, those points are worth resealing while access is already there. Reapplying protective coating to post faces and interior structure during a panel repair costs a fraction of what it costs to come back for the same bay twice. - Chalky bloom and stain streaks under rivet heads treated as a substrate warning - Post face treated or replaced rather than reskinned over pitted material - Roof to sidewall seams, drip rails and through wall mountings resealed while open - Protective coating reapplied to interior structure during panel repair - Repeat corrosion bays identified across the fleet and addressed as a pattern ## Peak season from October through December and DOT number lettering after panel work From October through December nothing can be off the road, and every logistics operator plans around that. The useful move is to treat the calendar as two different repair programs. Everything structural goes in before October: cracked lift gate mounting plates, out of plumb corner posts, doors that will not seal, corrosion that has reached the post. These are the items that degrade under peak load and that fail on the road at the worst time of year. Everything cosmetic waits for January, when a vehicle can sit without costing you a route. We schedule that way deliberately. Tell the estimator your peak window and the minimum number of bodies you need available and the sequence gets built around both. Deferred cosmetic work goes into the January trough. Structural work gets pulled forward into the late summer and early fall. Where a repair genuinely cannot wait during peak, we prioritize the operations that return the vehicle to service and write the rest as a scheduled follow up rather than holding the truck. Lettering is the last step and it deserves its own attention, because a body that has been repaired and repainted cannot run correctly identified until the graphics are back. Company livery, unit numbers and DOT number lettering come off with the panel and go back on after refinish. Usable vinyl is removed and preserved before paint. What cannot be saved is reordered to your spec and installed to the recorded placement measurements. Reflective conspicuity tape goes back in the same position and pattern it came off, on clean prepared substrate so it survives pressure washing. The drive is short. West Covina to the shop is about 22 miles and typically 30 to 45 minutes, usually the 10 or the 60 west to the 57 south, then the 91 east to Imperial Highway. Carbon Canyon Road across to the 71 is the local alternative when the 57 backs up through Brea, and it handles a straight truck comfortably. We are at 23281 La Palma Ave in Yorba Linda, open Monday to Friday 8:00 AM to 5:00 PM and Saturday 9:30 AM to 3:00 PM. Call (949) 799-3387 before bringing a combination unit so we can stage yard space. - Structural items scheduled before October, cosmetic backlog scheduled for January - Peak window and minimum available body count used to build the sequence - Livery, unit numbers and DOT lettering removed before paint and reinstalled after - Replacement vinyl ordered to spec and installed to recorded measurements - Conspicuity tape returned to its original position and pattern on prepared substrate - About 22 miles from West Covina with Carbon Canyon Road as the alternate route ## Frequently asked questions ### Why does my roll up door bind after a dock strike when the door itself looks fine? Because the opening moved, not the door. A dock strike at an angle bends the rear corner post or the header, and the track is no longer parallel to its own opening. The door then binds partway, the seal loses contact on one side, and the latch cannot reach. The fix is to straighten or replace the post and square the rear frame first, then rebuild the track, rollers, hinges, bottom panel and seal against a straight opening. ### How do I know whether our cargo bodies are sheet and post or FRP composite? Look at the exterior seams. Sheet and post bodies show vertical rivet lines at regular intervals where aluminum skin fastens to posts. FRP composite bodies present as wide smooth sections with very few seams and no rivet pattern. It matters because a sheet and post repair is a bay by bay panel replacement, while composite requires cutting back to sound laminate, scarfing, rebuilding the core and bonding new skin with cure time built into the schedule. ### Is a cracked lift gate mounting plate something we can run on until January? We would not recommend it. Mounting plate cracks are progressive: every cycle of the gate grows the crack a little, and the load path runs straight into the rear frame rail. Cracks at the weld toe or plate corners get worse fastest under heavy use, which is exactly what peak season delivers. Bring it in before October if you can. Cosmetic damage is a different conversation and defers safely. ### Will our DOT numbers and company graphics go back on after the body is repainted? Yes, and reinstallation is part of the job rather than an afterthought. Usable vinyl comes off before refinishing and goes back on afterward. Anything that cannot be salvaged is reordered to your spec and installed to the recorded placement measurements so lettering does not drift between units. Reflective conspicuity tape is reapplied in its original position and pattern on clean prepared substrate. Supply your artwork and placement standard once and we hold it on the account. ### Can you work on our trucks if a dealer handles our mechanical service? Yes, and that split is normal in logistics. Dealers and maintenance providers cover engines, drivetrains, transmissions, differentials, brakes and DOT inspections. We cover body, paint, structural, fiberglass, glass, equipment install and graphics: corner posts, roll up doors, panels, roofs, lift gate mounting, rivet line corrosion and livery. The scopes do not overlap, so nothing we do interferes with their side and nothing they do interferes with ours. --- OCRV Center, 23281 La Palma Ave, Yorba Linda, CA 92887. Phone (949) 799-3387.
