Chuck chuck chucking

FULL froward with the straight side of the hitch head supports towards the cab!!!

What air pressure are you running in your rear Dually tires and what is your rear axle weight loaded?

You have a great setup that should NOT cause chucking.

Are you running air bags?

Original OE shocks? If so get a set of Bilstein 4600's.

Hitch location in bed of the truck, move it forward and it will go away. Very common with short bed trucks, hitch is moved rearward for cab clearance. What you are experiencing is a light steer axle bounce. Move the center of pin forward of center of axle at least 2" to eliminate.

You need new shocks your shocks have gotten stiff causing a bounce when under load.

I disagree with it is the nature of 5th wheels to chuck.

I have had two 5th wheels and neither had chucking problems but I run 25 percent plus pin weights.

You said you are loaded heavy on the pin. What is your pin weight percentage. It may be less than you think.

You’ve got good equipment. I have the same without problems. Hope you get it figured out.

Maybe because of slop in the hitch and the trail air pin box allows the truck to pull ahead when the trailer lifts up because of the road conditions and so back and forth it keeps doing the same to have the chucking???

I know this happened to a friend with another brand of hitch.

It's the nature of the 5th wheel to do some chucking. Put the wheels in the middle of the trailer and you have a teeter-totter and chucking.

I guess what you consider chucking to be, I consider it to be fore-aft forces generated by the trailer and transmitted to the truck. A test for this would be to put your head on the head rest while traveling on rough roads and see if it bounces off. When your trailer pushes the pin down it also pushes forward resulting in chucking. Your Trail-Air pin box will dissipate the bouncing (up and down forces) but not the chucking forces due to its rear pivot point design. It could also be said that your pin box exacerbates chucking because the design pushes the pin forward when it compresses.

Usually, trailers that long don't chuck much due to their smaller hitch angle. I doubt moving the head assembly forward will help as the pin box is still securely attached to the frame of the truck via the hitch.

If you translate hitch noise and clunking as chucking then I still doubt adjusting your hitch will help.

I've had severe chucking issues when the brakes were never in play. I can see how a poorly dialed in brake controller will cause problems similar to chucking.


There was a member a couple of months back with similar gear and similar problems. He bought a Trailer Saver hitch and was very happy.


I'm back: That thread was titled 5er Hitch and was dated 8/21. It was in this forum.

I think the Trail Air is a great pin box for up, and down movement, but the Trail Air Flex, or MorRyde would help more with the chucking.

Adjust the response on the brake controller. The trailer brakes need to come on with the truck brakes not after. Chucking when you brake is due to poor brake controller adjustment. If you are talking about chucking at speed that may be related to your hitch or the road surface. If it is a up and down not a back and forth issue look at the hitch. If it is back and forth then look to the brake adjustment.
