RV Leveling Jack Repair

Your jacks are the foundation of a level, stable RV

If you've ever tried to cook dinner, take a shower, or just sleep in an RV that isn't level, you know how miserable it gets. Doors swing open on their own. The fridge doesn't cool right. Water pools in weird places. Your leveling jacks are the one system that keeps everything else working the way it should, and when they fail, you feel it immediately.

Scott Marlins has been repairing RV leveling jacks in Jensen Beach for over 10 years. With 3,200+ repairs under his belt across Martin County, he's seen every type of jack failure there is. From the Lippert ground control systems on newer fifth wheels to the older HWH hydraulic setups on Class A coaches, the diagnosis and fix usually happens in a single visit to your location.

Types of leveling jacks we repair

There are three main categories of RV leveling jacks, and each one breaks differently. Here's what we see most often.

Hydraulic leveling jacks are the most common type on Class A motorhomes and larger fifth wheels. They use hydraulic fluid pressurized by a pump to extend and retract the jack legs. The most frequent failures are seal leaks (you'll see fluid pooling around the base), pump motor burnout, and stuck check valves that prevent the jacks from holding position. HWH and Power Gear are the two brands we service most often in this category.

Electric leveling jacks have become the standard on travel trailers and mid-range fifth wheels over the past decade. Lippert's Ground Control and Level Up systems are everywhere. These use individual electric motors on each jack leg. Common problems include motor failure (the jack hums but doesn't move), stripped gears inside the motor housing, and control board communication errors where the system can't "see" one or more jacks.

Manual stabilizer jacks are the simplest type, usually found on smaller travel trailers and pop-ups. They don't break as often, but when they do, it's typically a bent shaft, seized threads from corrosion, or a worn crank mechanism. These are the quickest repairs we do.

Common leveling jack problems and what causes them

Over 10+ years of mobile RV repair, certain jack problems come up again and again. Here's what we see in Jensen Beach and why these failures happen.

Jacks won't extend or retract. This is the number one complaint we get. On hydraulic systems, it's usually a failed pump motor or a check valve stuck in the closed position. On electric jacks, a burned-out motor is the most common cause. Either way, the fix is straightforward once we open things up and test the components.

One jack extends slower than the others. For hydraulic systems, this points to a partially blocked fluid line or a leaking seal on that specific cylinder. The other jacks are getting more fluid because that one is losing pressure. On electric jacks, it could be a motor that's starting to fail or a corroded wiring connection reducing power to that leg.

Hydraulic fluid leaking from the jack. Florida's heat cycles are tough on rubber seals. We see this constantly between May and October when temperatures swing from cool mornings to 95-degree afternoons. The constant expansion and contraction wears seals out faster than in northern climates. A seal kit replacement costs roughly $150 to $250 and takes about 90 minutes.

The system runs but nothing moves. On hydraulic jacks, check the fluid reservoir first. Low fluid means the pump can't build pressure. If the fluid level is fine, the pump itself may have failed internally. On electric jacks, this usually means the gears inside the motor housing are stripped. The motor spins, but the drive mechanism doesn't engage.

Jacks won't hold position. Your RV settles down after you've leveled it, sometimes slowly, sometimes overnight. This is almost always a leaking check valve or a worn seal that lets hydraulic pressure bleed off gradually. It's a safety concern too, since a jack that drifts down while you're parked could cause the RV to shift unexpectedly.

Our repair process

Every leveling jack repair starts with a full diagnostic. We don't guess, and we don't replace parts hoping that fixes the problem. Here's what the process looks like.

Step 1: System test. We run the leveling system through its full cycle while watching each jack individually. This tells us immediately whether the issue is isolated to one jack, affects multiple jacks, or is a system-wide control problem.

Step 2: Component inspection. Once we've narrowed the problem down, we inspect the specific components. For hydraulic jacks, that means checking fluid levels, testing pump pressure, examining seals, and inspecting lines. For electric jacks, we test motor draw, check wiring continuity, and inspect the gear mechanisms.

Step 3: Diagnosis and quote. Before we touch a wrench, you'll know exactly what's wrong and exactly what it'll cost to fix. No surprises, no hidden fees. If the repair doesn't make financial sense (which is rare), we'll tell you that too.

Step 4: Repair and test. We complete the repair and run the full system through multiple leveling cycles to make sure everything operates correctly. We also check the other jacks for early signs of the same failure, since if one seal has gone, the others are usually on borrowed time.

Why jacks fail faster in Jensen Beach

Jensen Beach sits right on the coast, which means salt air, high humidity, and brutal summer heat. All three of these accelerate leveling jack wear. Salt corrosion attacks exposed metal components and electrical connections. Humidity promotes rust on jack housings and mounting hardware. And the heat (we regularly hit 92 to 95 degrees from June through September) breaks down hydraulic seals and dries out lubricant faster than in cooler climates.

RVs that park near the Indian River Lagoon or along Hutchinson Island see even more salt exposure. If your RV spends most of its time within a few miles of saltwater, we'd recommend inspecting the jacks every 6 months instead of annually. A quick $75 inspection can catch a $50 seal problem before it turns into a $400 cylinder rebuild.

Parts we keep in stock

One of the biggest frustrations with RV repair is waiting on parts. We stock the most commonly needed leveling jack components so we can complete most repairs in a single visit. That includes seal kits for HWH and Power Gear hydraulic cylinders, replacement motors for Lippert electric jacks, check valves, hydraulic lines and fittings, and solenoid valves. For less common parts, we can usually have them delivered next-day to Jensen Beach through our supplier network.
