Recognizing the Signs

If you're experiencing this issue, you're not alone. Here's what's typically happening and how to address it.

What You Might Notice

When your RV stabilizer jack handle spins freely but won't raise the jack, you're dealing with stripped internal gears, a broken drive shaft, or disconnected internal components. Note that stabilizer jacks use different internal mechanisms (worm gear, acme screw, or gear reduction systems) which may require different repair approaches - consult your jack's manual for specific procedures.

Root Causes

Stripped drive gears: The small gear that connects to the handle is usually made of softer metal and strips first when the jack is overloaded or corroded.

Corrosion and rust: Moisture infiltration causes internal components to rust together, especially in the drive mechanism housing.

Overloading: Using stabilizer jacks to actually lift the RV rather than just stabilize it puts excessive stress on the gear mechanism.

Lack of maintenance: Old grease becomes thick and acidic, accelerating wear and corrosion of internal parts.

Bent drive shaft: Impact damage or forcing a stuck jack can bend the internal drive shaft, causing it to slip or bind.

What to Grab

• Socket wrench set
• Penetrating oil (WD-40 or PB Blaster)
• Replacement gears or jack rebuild kit
• Grease (marine-grade or lithium)
• Wire brush or steel wool
• Safety glasses
• Work gloves
• Jack stands or blocks for support

How to Fix It

1. Safety first: Before disabling any stabilizer jack, ensure the RV's weight is properly supported by other means. Ensure your RV is level and secure. Never work under an RV supported only by stabilizer jacks - use proper jack stands if needed.
2. Remove the jack handle and inspect it for wear. Some handles have a square drive that can become rounded off.
3. Locate the access cover on your stabilizer jack. Most manual jacks (Barker, Ultra-Fab, Husky) have a removable cover or cap that allows access to internal components.
4. Spray penetrating oil around all visible components and let it sit for 15-20 minutes to break up corrosion.
5. Remove the cover bolts carefully - these are often corroded. Clean threads with a wire brush if needed.
6. Inspect the internal gears. Look for stripped teeth, broken gears (typically worm gears, pinion gears, or drive gears depending on your jack type), or a disconnected drive shaft. The most common failure is the small drive gear that connects to the handle.
7. Remove damaged components by noting their position and orientation before disassembly. Take photos if helpful.
8. Clean all parts thoroughly with degreaser and inspect the jack tube for damage or excessive wear.
9. Install new parts in reverse order, ensuring proper alignment. Most stabilizer jack manufacturers sell individual gears or complete rebuild kits.
10. Apply fresh grease to all moving parts before reassembly. Use white lithium grease or RV-specific jack grease to prevent future corrosion.
11. Test the mechanism by hand before fully reassembling to ensure smooth operation.
12. Reassemble the cover and test with the handle. The jack should raise and lower smoothly without binding.

Leave These to the Experts

Consider professional help if you encounter:

• Severe corrosion that has damaged the jack housing or mounting brackets
• Bent or damaged jack legs that affect structural integrity
• Multiple jacks failing simultaneously, which may indicate RV frame issues
• You're uncomfortable working with the RV's support systems
• The jack mechanism is integrated with electric or hydraulic systems
