Fifth Wheel Hitch Maintenance
A little grease goes a long way. Keep your hitch happy.
The Basics
Fifth wheel hitches are built tough, but they still need attention. Regular maintenance prevents noise, wear, and that awful moment when something doesn't work right at the campground.
Lubrication
The most important maintenance
Hitch Plate / Skid Plate
This is where your trailer's pin box slides and pivots. It needs to be slick.
What to use:
- • Fifth wheel grease (best)
- • Lithium grease
- • Some use motor oil (works but messy)
How often:
Before every trip, or at least monthly during towing season.
Jaw / Locking Mechanism
The jaws need to move freely to lock and release.
What to use:
- • Light machine oil
- • Spray lubricant (not WD-40)
- • Grease on pivot points
How often:
Every few trips or when mechanism feels stiff.
Slider Rails (If Applicable)
Sliders need to slide smoothly, especially in an emergency.
What to use:
- • Lithium grease
- • Dry lube (less dirt attraction)
How often:
Before every trip. Test that it slides freely.
Inspection Checklist
What to look for
Mounting Bolts
Check that all bolts are tight and torqued to spec. Vibration loosens things over time.
Jaw Wear
Look for excessive wear on the jaw surfaces. Some wear is normal; deep grooves mean replacement time.
Locking Indicator
Make sure the indicator (if equipped) clearly shows locked/unlocked positions.
Handle Operation
Release handle should work smoothly without excessive force.
Cracks or Damage
Look for cracks in the head, welds, or mounting brackets. Any crack = don't tow until fixed.
Cleaning
Before you re-grease
Old grease attracts dirt and grime. Clean before applying fresh lube.
- 1. Scrape off old grease with a plastic scraper
- 2. Wipe down with a rag
- 3. For stubborn buildup, use brake cleaner or degreaser
- 4. Let dry completely
- 5. Apply fresh grease
Off-Season Storage
Protect it when not in use
If Leaving in Truck
- • Apply a heavy coat of grease
- • Cover with a hitch cover or tarp
- • Check periodically for rust
If Removing
- • Clean thoroughly
- • Apply rust inhibitor
- • Store in a dry place
