trailer bounce

[Mpsoldier]

alright guys seeing if anyone else has this problem. I have a 2014 deck-over trailer 22' power up and down 14k. when driving unloaded with the trailer i get this horrible bounce in the truck annoying as shit only between 30-35mph. i have tried balancing tires on trailer and checking trailer tire pressure, raised ball height and lowered it. Both 2002 cc sb and my 2006 cclb do this. one truck has bilstein 5100's other has rancho 9000's. seeing if any one has ideas.

If you unhook the trailer do the trucks bounce? Or only when the trailer is hooked up?

only when the trailer is hooked. Only this trailer, I have a 36' enclosed doesn't do it with and if the trailer is loaded it wont do it. I have plenty of tongue weight as I have a box full of chains up front. and a winch mounted into the kick board.

Are the axles bent by chance??

Try taking the chains and what not out of the box and see if it goes away. You may be hitting a frequency point at that speed causing the bounce. Bias or radial tires? Load range?

Is it only when cruising at that speed what about on accel and and decel?

My dad just bought a brand new 14' deck over and does the same thing unloaded 100% empty (no toolbox, chains, etc). We kinda decided it was nature of a deck over

Trailer isn't heavy enough to make the suspension work while empty

Emptied the box today no difference and between 30-35 is the spot annoying as shit. And accelerating up hill I get a little bounce but nothing crazy. I know the roads suck up in ct and mass but man it sucks when you feel like your in a washer machine. Forgot to mention my 06 is a 3500 srw same shit.

Figured the trailer weighting in at 4k never thought it wouldn't be heavy enough.

Stock tires I will find out tomorrow the specs. Pouring here

Does it only happen on certain roads? Sometimes mine does that empty going down the interstate.....

Doesn't matter the road highway back roads don't matter

Empty, there is not enough tongue weight. That makes the trailer pivot point (center of gravity) line up closer or aft of the axle center line and the trailer will buck.

Weight half way between the axle and hitch might help. There are also hitch dampeners that can be effective. Ultimately though, it is in the trailer design. The only solution would be to move the axles further back.

^ what they said its just the design of it and being empty.

I have the same issue with a brand new car hauler. trailer is heavy enough I can occasionally feel it bucking the truck when its empty but its not heavy enough to flex its own suspension.

I put any weight on the trailer and the issue goes away.
