Get your slide moving again with hydraulic parts like a power unit for reliable in-and-out operation. Match your existing pump style and reservoir size, refill with AW-32 hydraulic fluid, and check wiring compatibility for an easy swap. If a slide creeps, verify valves and seals or purge air in the lines before assuming the power unit is at fault.
Yes, a Lippert replacement Power Unit with a 2-quart reservoir can replace certain older Haldex systems. If the original 2-qt reservoir is damaged, available replacements are paired with the pump rather than sold separately. Confirm your current brand and reservoir size for compatibility.
Yes, some Lippert slide-out Power Unit motors can be replaced separately. Check the pump assembly number on your unit to match the correct motor. If your slide was out of alignment or under heavy load, fix that first so the new motor isn't strained. Weak movement that needs assistance can point to a failing motor.
Start by running the slide in and out 5 times to purge air. Check for fluid leaks at lines, cylinders, and the pump. Inspect the solenoid valve at the Power Unit; open it about one turn with a hex key and then close it to help the seal. If creep continues, the valve or cylinder may need replacement.
Replacing a Power Unit is generally straightforward. Installs are often a direct fit and can go quickly with basic tools. Label hoses and wiring, reconnect carefully, and tighten fittings. Afterward, cycle the slide to confirm smooth operation and recheck for leaks.
Use AW-32 Hydraulic Fluid, not automatic transmission fluid. Verify the reservoir level and add AW-32 as needed. After topping off or opening lines, run the slide in and out several times to help purge air.
