I have a 2018 150 2.7eb and a 7.5x12 utility trailer that weighs 900lb empty while towing my truck shakes and vibrates like a dog crapping razor blades. slow down speed up no difference trailer is new and pulles straigt on other trucks anyone have any ideas or experianced the same thing?

 

Try adding some weight to the trailer. Some trailers with very little tongue weight get squirly.

 

Had a similar issue towing empty U-haul car trailer, would shake like crazy. Once the car was loaded it was fine.

I also recommend balancing trailer tires - makes a world of difference even though shops will say it's not needed.

 

I put my golf cart on the trailer for the return home thats what I was doing picking it up from the shop I placed it as far forward as i could to try and load the hitch but it still did it no issue without trailer. I have towed the trailer with a ford escape with no issues also. I see other threads about this but no definite answers.

 

Is the hitch drop enough that the trailer is level? If not, there will be no tongue weight or negative tongue weight, which would cause your problem.

 

Yeah, I don't get that. Balancing makes everything smoother and is much easier on the bearings.

 

X2, that irks me, along with them not making any attempt to line the dot on the tire up with the valve stem. It is designed to be the optimum place ... hence lest weights for a better initial balance.

back to the OP, So it's squirly empty AND with a golf cart? I could see a golfcart and a roof creating crazy winds.

Golf cart no cart no difference. Its not like its squirly handling it steers straight and true just shakes/vibrates.I got home last knight and checked it looks pretty level to me tires have been balanced. I do have an adjustable height ball will try to set the ball low and see if that makes a difference .

 

I get the same thing and they tell me I'm crazy. Pull a trailer with balanced tires vs unbalanced and you'll see the difference.
I am thinking your hitch height is off, if you lower it you may see quite the difference, though I will say the roughest pulling trailers for me have always been small single axle tilt trailers. They are designed with the axle in the center of the bed so that it will tilt and without weight upfront they are just bouncy as all get out. You might try lowering the tire PSI a bit to see if that helps.

 

A few years back I bought a brand new car trailer.It bounced my truck around on the drive home.I took it to my buddies shop to balance the tires.They were chinese tires and were all out of round.Some as much as a 1/2 inch.I took it back to the trailer dealer and we went through about 8 tires before we found 4 round ones.I remember the brand of the tires was "PERFECT".Not hardly.After about 10k miles of use they were wore out..

 

When I replace trailer tires, I always try to find an LT rated truck tire in the same size or close to it.

 

Why not ST(Special Trailer) tires? LT tires are designed for driving and/or steering, and ST tires have heavier sidewalls, as their primary requirement is load handling

So many ST tires are made in China and just don't hold up. LT tires have a better speed rating and generally last much longer.

 

Goodyear has a new trailer tire that has been out a few years.They are called there Goodyear Endurance.They have a higher weight rating compared to most other trailer tires and are made in America.I have them on two of my trailers so far and they all balanced out near perfect.
