Hey folks,

Vehicle in question is a 2017 F150, 3.5/10 speed. Factory tow package.

I hooked up a small trailer w/ side by side today (3500lbs total) and above 60mph I got a pretty bad vibration. I could feel it in the steering wheel (visibly shaking if I let go) and could feel it through the seat as well. Towed the same setup with my '13 F150 and it didn't shake at all. Between 70-75 mph the vibration decreased.

Unloaded, the truck rides like butter. No vibration at all. Little puzzled at this point.

All tire pressures are were they should be, trailer was just serviced and everything is tight and new.

 

I had a re-flash/reset on my trans...dealer said there was an update.....also have you broke in ....mileage to break in truck before towing.....and tow haul mode??

 

Yeah, i'm at 3500km, and using tow haul.

 

I get weird vibrations at certain speeds with my snowmobile trailer behind the JGCL. Nothing with my truck. Happens with my buddies Edge.

My issues is an aerodynamic issue.

Was the trailer loaded? If not, put 500#s in and see what happens.

 

could you throw up a photo or make/model of trailer? also where was placement of UTV on trailer?

 

Sure:

Here's the trailer/sxs behind my old truck. Same setup on this one.

 

Tire out of balance on the trailer maybe? load the sxs on backwards the next time and see if the weight shift changes any thing,its not the truck for sure or it would happen with out the trailer ,

 

I would have the trans programming checked.....its new.....like i said... they/dealer did something or a reset and my 6spd has been fine since..
My loads ..

 

^ I have the 10 speed, nothing relating to your 6 speed is relevant. Nice truck though!

 

Hmm... Good idea on loading backwards. I'll try it
