Posted rates at https://ocrv.biz/prices/ ## Which slide mechanism does your RV have? Look at the outside of the slide box and underneath the vehicle. That answers it in under a minute. | Mechanism | How to spot it | Typical failure | Schwintek in wall | Toothed vertical tracks on both side edges of the slide box | Motors out of synchronisation, stripped gear teeth, controller faults, room binding in the opening | Through frame rack and pinion | A steel gear rack running under the slide floor, driven by one motor | Worn gear teeth, bent rail, motor and gearbox failure, room out of square | Cable driven | Cables and pulleys at the four corners inside the room opening | Cable stretch, frayed strand, pulley seizure, uneven travel top to bottom | Hydraulic | Rams, hoses and a pump, usually shared with the leveling system | Ram seal leaks, low fluid, solenoid failure, one ram extending ahead of the other Lighter slides on towables and smaller coaches are usually Schwintek. Heavy full wall slides on larger Class A coaches are usually hydraulic. The technical detail on each drive system is on the [slide out repair service page](/services/slide-out-repair/). ## What is your slide actually telling you? Match the symptom to the likely cause before spending money on parts. - **Clicking or ratcheting with no movement.** On a Schwintek this usually means a motor has lost synchronisation or gear teeth have stripped. Continuing to cycle it makes the damage worse. - **Room extends crooked, one end leading.** Synchronisation on a two motor system, or a stretched cable on a cable slide. Forcing it square by hand damages the wall opening. - **Grinding.** Metal on metal contact somewhere in the drive. Stop and have it looked at, because grinding is how a repairable gear becomes a replaced rail. - **Moves slowly, then stalls partway.** Low voltage under load is a common culprit, especially with a tired house battery bank. Slides draw heavily and are unforgiving of weak batteries. - **Works fine but leaks.** That is a seal job, not a mechanism job. Wiper, bulb and D seal replacement runs $400 to $3,000. Slide mechanism service overall runs $500 to $8,500 and 3 to 35 labor hours at $260 per hour for mechanical and electrical work. Figures come from the [posted rate card](/prices/). ## When does a slide problem become a structural repair? When the room itself has failed rather than the thing that moves it. A slide room is a box with its own floor, walls and roof, and it takes weather on all sides while extended. Water gets in at the top seal, soaks the room floor, and the floor sags. A sagging room binds in the opening, and the mechanism that has been fighting that bind for two seasons is the part that finally breaks. Replacing the motor on that vehicle solves nothing. Slide room rebuild and structural repair runs $1,500 to $7,500 and 10 to 35 labor hours, and it involves opening the room, replacing wet decking and framing, and resetting the room square before the drive components go back. The tell is at the floor edge. Walk to the outer edge of an extended slide and press down. If the floor gives noticeably at the outer corners, the room has taken water, and the mechanism conversation is premature. ## Is a slide topper worth putting back on? Yes, on any slide that spends real time extended outdoors. A topper is a fabric awning over the slide roof that keeps debris and standing water off the top seal. Without one, pine needles and leaf litter collect on the slide roof, hold moisture against the seal and the sealant, and that is the leak path that eventually costs a room rebuild. Topper replacement runs $450 to $1,800 and 3 to 8 labor hours, which is inexpensive relative to what it prevents. The common failure is fabric that has gone brittle and split along the roller, or a torsion spring in the roller that has lost tension so the fabric sags and pools water. If your slide has never had a topper, adding one is straightforward on most units. If yours tore and you have been running without it, add a seal inspection to the same visit.

A gear rack under the floor means through frame. Cables at the corners means a cable slide. Rams and hoses under the chassis means hydraulic. Everything downstream depends on this. 2. **Cycle and observe under load**: The slide is run in and out while a technician watches both sides for lead, lag and bind. Most slide problems show themselves in the first six inches of travel, and a slide that walks out crooked has a synchronisation issue rather than a motor issue. 3. **Check the room, not just the drive**: A slide floor that has absorbed water gains weight and sags, which overloads the mechanism that was blamed for the failure. Room structure, floor condition and the wall to room seal are inspected before any drive part is ordered. 4. **Repair, resynchronise and seal**: Drive components are repaired or replaced, the room is set square in the opening, travel limits are reset, and the wiper, bulb and D seals are checked for contact along the entire perimeter. The slide is then cycled repeatedly before the vehicle is released. ## Questions ### My slide is stuck out and I need to move the RV. What now? Most systems have a manual override, and which one depends on the mechanism. Schwintek and through frame systems generally have a way to disengage the drive and push the room in. Hydraulic systems have a manual release on the pump. Getting the room in far enough to travel safely is the priority; do not drive with a slide partially extended. ### Why does my slide leak only when it rains hard? Because the wiper seal handles running water but not driven water. Under wind pressure, water finds the top corners where the wiper, bulb and D seals meet, and any gap in that transition lets it in. The fix is usually seal replacement plus resetting the room so it sits square in the opening and loads the seals evenly. ### Can a Schwintek system be converted to something else? Rarely worth it. The in wall design integrates with the sidewall structure, so converting to a through frame system means rebuilding the wall and the floor. The more productive path is correcting whatever is causing the bind, keeping the tracks clean and the room square, and replacing worn drive components with the correct parts. ### How long does slide work take? Seal replacement is 2 to 14 labor hours and often a same week job. Mechanism repair is 3 to 35 hours and depends heavily on parts availability, since slide drive components are model specific and not always stocked. A room rebuild is 10 to 35 hours plus material and cure time. ### Do you work on slides in fifth wheels and travel trailers? Yes, and towables make up a large share of slide work. Fifth wheels commonly run three or four slides across the living area and bedroom, often on different mechanisms in the same unit, so identifying each one separately is part of the initial evaluation rather than an assumption. ## Related - [Slide-Out Repair](https://ocrv.biz/services/slide-out-repair/) - [Awning Repair](https://ocrv.biz/services/awning-repair/) - [Campers and Trailers](https://ocrv.biz/vehicles/campers-trailers/) - [Electrical Repair](https://ocrv.biz/services/electrical-repair/) - [Prices and Posted Rates](https://ocrv.biz/prices/) - [RV Repair](https://ocrv.biz/rv-repair/)
