Thank Igave and FR Diesel, these are great points. My plan, from all the information from all you great people out there. Maybe a preliminary check sheet for people in similar circumstances (please feel free to add and/or edit to refine). I will try to link the individuals and forums that have helped me with this and give proper credit. Also, anyone who reads this, please know that these are temporary ideas and that repair at a service repair shop is the definitive solution.
Step-by-Step Procedure for RV Hydraulic Troubleshoot and Temporary Fixes
Step 1: Clean Hydraulic Pump/Manifold/Compartment:
a. Ensure the hydraulic system is turned off and all components are cool.
b. Use a suitable cleaning solution and a lint-free cloth to wipe down the hydraulic pump, manifold, and compartment.
c. Pay close attention to removing any dirt, debris, or oil residue from the surfaces.
d. Inspect the components for any signs of damage or leaks. If leaks are detected, proceed to step 2 before continuing with the cleaning process.
Step 2: Perform Equalizer Systems (or applicable manufacturer) Air Bleed Procedure and Check for Leaks:
a. Refer to the manufacturer's instructions or maintenance manual for the specific air bleed procedure for your Equalizer Systems hydraulic system. See the post #3 above by Lincman983
b. Follow the recommended steps to bleed air from the system, ensuring proper hydraulic fluid circulation.
c. While performing the air bleed procedure, inspect the pump, manifold, and hoses for any pinhole leaks or other signs of fluid leakage.
d. If leaks are found, address them accordingly, either by tightening connections or replacing damaged components.
e. If the hydraulic fluid level is low, evaluate the need for additional fluid, (with all hydraulics retracted
Step 3: Equalize Pressure Before Slide Retraction:
a. Just before retracting the slides, as the slides approach the fully closed position, release the retraction switch to stop the movement just as they close.
b. Immediately after the slides close, give a very brief bump to the extend switch to activate the hydraulic system in the opposite direction.
(This action helps equalize the pressure in the hydraulic lines, reducing slide movement during travel).
Step 4: Secure Slide-outs for Travel:
a. Use ratchet straps to secure the slide-outs to the chassis, providing extra reinforcement, stability, and peace of mind during transit.
b. Position slide locks (commercial or 2x4s) in place according to the manufacturer's instructions, ensuring they are correctly engaged to prevent unintended movement. Suggested to position slide locks across all three sides of slide-out to prevent pressure being unevenly dispersed.
Step 5: Isolating Slide-out Hydraulics (highly recommended):
Consult with an Equalizer Systems Technician and follow these steps if an internal cylinder leak is suspected:
Identifying the Hydraulic Cylinder:
Locate the hydraulic cylinder that potentially has an internal leak. Accurate identification of the cylinder is crucial for the isolation procedure.
Retracting all Cylinders (Slide-outs):
If the hydraulic cylinder is part of a system with multiple cylinders, retract all the other cylinders, such as slide-outs, to relieve pressure on the cylinder being isolated. This minimizes the risk of unexpected movements and potential hazards during the isolation process.
Slowly Releasing/Opening the Retract Side of the Cylinder:
Locate the retract side of the hydraulic cylinder and use appropriate tools to slowly release or open the valve controlling that side. This allows the hydraulic fluid to drain from the cylinder. Place absorbent pads or towels beneath the cylinder to contain any spills.
Slowly Releasing/Opening and Extending the Side of the Cylinder:
Locate the extended side of the hydraulic cylinder and use appropriate tools to slowly release or open the valve controlling that side. This action allows the hydraulic fluid to drain from the cylinder. Again, be prepared for fluid drainage and have absorbent pads or towels in place.
Capping Both Ends of the Hydraulic Cylinder:
Once the hydraulic fluid has drained, cap both ends of the cylinder using appropriate caps or plugs. This prevents further leakage during the isolation process.
Capping the Hydraulic Hoses to and from the Cylinder:
Identify the hydraulic hoses connected to the isolated cylinder and cap both ends using appropriate caps or plugs to prevent hydraulic fluid leakage.
If the hydraulic cylinder is used for slide-outs, ensure that the slide-outs are securely locked in place. Use ratchet straps and slide-out locks to immobilize the slide-outs, preventing unintended movement while the cylinder is isolated.
Step 6: Monitor Hydraulic Leveling System During Travel:
a. While on the road, periodically check the hydraulic levelling system for any error noises or lights that could indicate the jacks are extending unintentionally.
b. If any abnormal noises or warning lights are observed, safely pull over and investigate the issue before continuing.

Although specific to FR Berkshires, something to consider when discussing repair for hydraulic cylinders on MH. https://www.forestriverforums.com/fo...tml#post716310
