Troubleshooting Common Problems
Something not working right? Here are the usual suspects.
Hitch is Noisy
Clunking, squeaking, popping
Clunking When Starting/Stopping
Cause: Slack between kingpin and jaws. Normal with some hitches, but excessive play means wear.
Fix: Check jaw adjustment if your hitch has it. Some hitches have lash adjusters. If jaws are worn, may need replacement.
Squeaking When Turning
Cause: Dry skid plate. Metal-on-metal contact.
Fix: More grease on the hitch plate. Apply liberally and re-check after a trip.
Popping/Snapping Sound
Cause: Usually the pin box pivoting on a dry hitch plate, or the trailer's front cap flexing.
Fix: Grease the skid plate. If it persists, the sound may be from the trailer, not the hitch.
Chucking / Bucking
Jerky ride, especially on rough roads
Chucking is that jarring back-and-forth motion you feel when the trailer and truck aren't moving together smoothly. It's uncomfortable and hard on your truck.
Cause 1: Kingpin Play
Fix: Tighten jaw adjustment if available. Some play is normal, but excessive play causes chucking.
Cause 2: Standard Pin Box
Fix: Upgrade to a cushioned or air-ride pin box. These absorb the motion before it reaches your truck. Popular solution for chucking.
Cause 3: Trailer Suspension
Fix: Sometimes it's the trailer, not the hitch. Have the trailer suspension checked.
Pro Tip
Air-ride pin boxes (like MORryde or Reese) are the most effective solution for chucking. They're not cheap ($800-1,500) but they transform the ride.
Hitch Won't Release
Kingpin stuck in jaws
Don't Panic
This is almost always fixable at the campsite. Don't try to drive or drag the trailer — you'll damage something.
Step 1: Check the Obvious
- • Is the safety pin/clip removed?
- • Is the handle fully in the release position?
- • Is there weight on the hitch? (jacks not supporting trailer)
Step 2: Remove Weight from Kingpin
Lower your trailer's front jacks to lift the pin box off the hitch plate. This removes binding pressure from the jaws.
Step 3: Rock the Trailer
With jacks supporting the weight, have someone gently rock the trailer while you work the release handle.
Step 4: Drive Forward Slightly
With jacks down and release handle in position, inch forward to change the angle. Sometimes that's all it takes.
Step 5: Lubricate
Spray lubricant on the jaw mechanism. Work the handle back and forth.
Still stuck? Call a mobile RV tech. Don't force it and break something.
Hitch Won't Lock
Indicator doesn't show locked
Kingpin Not Fully Seated
Fix: Lower trailer jacks more. The kingpin needs to drop fully into the jaws. Sometimes it catches on the edge.
Debris in Jaws
Fix: Check for rocks, sticks, or ice in the jaw area. Clean it out.
Mechanism Stuck
Fix: Work the handle several times. Apply lubricant. Check for rust or binding.
Worn Components
Fix: If nothing else works, the locking mechanism may be worn. Time for service or replacement.
Never Tow Without Verified Lock
If you can't get a solid lock indication, don't tow. Period. Fix it first.
Slider Won't Move
Stuck forward or back
Pin Not Released
Make sure you've fully released the locking pin. Some have two — check both.
Weight on Slider
The trailer's weight can bind the slider. Use the trailer's jacks to lift some weight off before sliding.
Dry Rails
Slider rails need lubrication. Apply grease and work the slider back and forth.
Rust/Corrosion
If stored outside without cover, rails can rust and bind. Clean with wire brush, apply rust inhibitor, then grease.
