ALLIANCE AVENUE 32RLS – Stabilizer Jack Replacement

Dealer service bulletins won’t mention it, and your Alliance Avenue 32RLS owner’s manual certainly won’t flag it as a predictable failure—but the stabilizer jack on these rigs fails in ways that are almost as reliable as the sunrise. I’ve pulled dead motors out of a dozen of these trailers, dealt with seized scissor mechanisms that haven’t moved in three seasons, and replaced cracked welds at the base where lateral pressure from an uneven campsite finally does the damage. What surprises most owners is how quickly a bad stabilizer cascades into other problems: your slide-out seals start taking a beating with each sway, cabinet doors stop closing flush, and the whole rig starts feeling like it’s floating instead of planted. The repair isn’t complicated—it’s the kind of job that teaches you something about your rig’s framework while you’re under there with wrenches in hand.

The Lippert PSX1: The Upgrade That Actually Solves the Avenue 32RLS Stabilizer Problem

Your Alliance came with a stabilizer jack that was engineered to a price point, not to the realities of constant travel and weather exposure. The motor gives up, corrosion eats the scissor linkage, fatigue cracks split the welds—and none of it’s a surprise once you’ve seen it happen. The PSX1 changes the equation: heavier motor, sealed construction that doesn’t invite every dust cloud and salt spray into the mechanism, and an automatic leveling system that removes the guess-work entirely.

The real advantages

• Self-leveling takes the manual adjustment out of the equation—deploy it and walk away; the PSX1 extends to the exact height needed without over-stroking the motor or risk of you cranking it past its limit.
• Sealed motor housing and heavy-wall steel frame construction keeps the road salt, sand, and constant highway vibration from eating away at the gears and winch the way your OEM jack’s exposed design allows after a couple of seasons.
• The 30-inch stroke is sized specifically for the Avenue’s ride height—you’re not forcing an undersized jack to reach elevation or dealing with the binding and motor strain that comes from fighting inadequate extension.

Where the complications hide

• The control switch assembly doesn’t come in the box; you’ll either salvage and rewire your old switch (if it’s still functional) or source a replacement control panel from Lippert—both paths add time and unexpected expense at checkout.
• Mounting the PSX1 may require drilling out new attachment points; the Alliance’s frame geometry doesn’t always line up with universal mounting holes, and you might need fabricated mounting brackets or a welder’s help to get it solid.

I had one installed on my own Avenue last year and honestly second-guessed whether the PSX1 overkill until I hit a pothole at 55 mph and watched the jacks auto-retract instead of bottoming out—that’s when I knew the part choice was right. Order the Lippert PSX1 High-Speed RV Power Stabilizer Jack System, No-Switch Assembly, Automatic Adjustment, Heavy-Gauge Powder-Coated Steel Frame, Up to 30″ Extension – 337199 and budget for a second tech visit if you’re not comfortable with the frame mount.
