If you're a proud owner of a Forest River RV with hydraulic slide outs, you're likely familiar with the convenience and extra living space they provide. However, like any complex mechanical feature, they can sometimes present issues. This article aims to help you understand common Forest River RV hydraulic slide out problems, their causes, and potential solutions.
Understanding Hydraulic Slide Out Systems
Before delving into the problems, it's crucial to understand how hydraulic slide out systems work. These systems use a hydraulic pump to move the slide out in and out. The pump is powered by the RV's 12-volt electrical system. The slide out's position is controlled by a switch, usually located near the entry door.
Common Forest River RV Hydraulic Slide Out Problems
Slow or Jerky Movement
One of the most common issues is slow or jerky movement of the slide out. This could be due to a few reasons:

- Low Power: The hydraulic pump might not be receiving enough power, causing the slide out to move slowly.
- Air in the System: Air bubbles in the hydraulic fluid can cause jerky movement. This is often due to a leak in the system that allows air to enter.
- Worn Out Seal: A worn-out seal on the hydraulic cylinder can cause air to leak into the system.
Noise Issues
Another common problem is excessive noise when the slide out is in operation. This could be due to:
- Worn Out Pump: The hydraulic pump might be worn out and need replacement.
- Lack of Lubrication: The slide out system requires regular lubrication. Lack of lubrication can cause excessive noise and wear on the system.
Slide Out Won't Retract or Extend
If your slide out refuses to move at all, it could be due to:
- Faulty Switch: The switch that controls the slide out might be faulty. Try testing the switch with a multimeter to confirm.
- Blockage: Something might be blocking the slide out from moving. Check for any obstructions and ensure the path is clear.
Preventive Maintenance for Hydraulic Slide Outs
Regular maintenance can help prevent many of these issues. Here are some tips:

- Regularly lubricate the slide out system according to the manufacturer's instructions.
- Inspect the hydraulic lines for any leaks or damage.
- Test the slide out system regularly to ensure it's working properly.
- Keep the area around the slide out clear of debris and obstructions.
When to Call a Professional
While some issues can be troubleshot and fixed by the RV owner, others require professional help. If you're not comfortable working on the hydraulic system or the problem persists after attempting troubleshooting, it's best to call a professional RV technician.
| Problem | Potential Cause | Solution |
|---|---|---|
| Slow or Jerky Movement | Low Power, Air in the System, Worn Out Seal | Check and replace hydraulic fluid, bleed the system, replace seals |
| Noise Issues | Worn Out Pump, Lack of Lubrication | Replace pump, lubricate system |
| Slide Out Won't Retract or Extend | Faulty Switch, Blockage | Test and replace switch, clear obstruction |
In conclusion, while Forest River RV hydraulic slide out problems can be frustrating, they're often preventable with regular maintenance and troubleshooting. Always remember to consult your RV's owner's manual for specific instructions and safety guidelines.
