ALLIANCE AVENUE 32RLS – Stabilizer Jack Replacement

I keep the most common failure components stocked in my van because certain repairs come up so predictably I’d lose time driving to a supplier. When I show up to a rig and already know what’s wrong before I open the access panel — that’s not experience, that’s pattern recognition from seeing the same failure hundreds of times. The Alliance Avenue 32RLS stabilizer jack is exactly that kind of repeat offender — the electric motor burns out, the scissor mechanism seizes from road grime and neglect, or the weld points crack under the lateral stress of an unlevel site, and suddenly a rig that felt rock-solid is swaying every time someone walks to the bathroom. It’s not just a comfort issue either; a failed stabilizer puts stress on your slide-out seals, your cabinetry, and your leveling system in ways that quietly stack up into expensive secondary damage. What follows is the same procedure I run through on-site, documented clearly enough that a capable DIYer can handle it without a service call.

The Lippert PSX1: The Only Jack System Worth Installing on an Avenue 32RLS

The OEM stabilizer jack on the Alliance Avenue 32RLS fails because it was never designed to handle the flex and vibration of highway miles—the motor burns out, the scissor mechanism corrodes, and you’re left shimming blocks under the frame. The PSX1 addresses both failure points with a heavier-duty motor and sealed construction that actually survives repeated extend-retract cycles.

What works

• The automatic height adjustment means you don’t have to manually dial each jack—it levels itself within seconds of being deployed, no guessing, no over-extension that strips the motor.
• Heavy-gauge steel frame and sealed motor housing keeps road salt, dust, and vibration from degrading the internals the way the OEM design does after two seasons.
• 30-inch extension covers the Avenue’s ground clearance needs without the binding or torque twist you get when forcing an undersized jack to reach full height.

What doesn’t

• Ships without the switch assembly included, so you’re either rewiring the old switch (if it’s salvageable) or buying a replacement control panel separately—adds cost and labor time you don’t expect.
• Installation requires drilling new mounting holes if the original jack footprint doesn’t align perfectly; the Alliance’s frame geometry means you may need to fabricate mounting plates or have a welder involved.

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.
