Shake/Vibration when Towing

[Caman96]

Take it for what it’s worth, this is from E-trailer:
There are a few different causes for the steering wheel to shake while towing. The tires as you mentioned could be out of balance but they would have to be pretty far off in order to shake the vehicle's steering wheel. The way the trailer is loaded is also a potential cause. The trailer needs to be loaded so that 60% of the weight is in front and 40% is in the back. Have you tried to load the UTV further forward or backward? The last potential cause I can see is a stiff suspension. If the leaf springs have not yet broken in then this could be what is casing the shanking as the suspension is not absorbing road shock and is then transferring that back onto the vehicle.

I would first try to move the weight around on the trailer and then balance the tires if moving the weight around does not help. The last option would be to take the trailer back to the dealer and have them look it over for you.

^^^That was an answer to someone else’s question.

I do check it often, everything is tight. There is no rot on truck. What corrections would you make to alignment?

None. If it's primary use is unloaded I'd figure out how to balance the trailer better before I messed with the loaded alignment.

Again, I have towed these with another truck smooth as butter. Load can’t be shifted around on this trailer.

The 60/40 statement is a myth. It needs to be loaded level. The axle(s) on the trailer carry weight and the tongue carries weight which gets shifted to the truck.

It can be added though. If you have too much tongue weight you can add weight to the rear of the trailer to get it balanced better. Cinder blocks or old batteries work well.

So, with the placement of the axle where it is and with both Atv’s loaded in, there is virtually nothing I could do for shifting. I could add weight forward or aft though.

While you were typing that....lol

What about HotWheels way of dropping a bit in front so it’s not perfectly level?

I would only load the front atv and go try it.

I'm not necessarily advocating for messing with it, rather characterizing it. There may be nothing wrong with the loaded alignment.

Yeah that's just dumb. 10-15% should be tongue weight for a bumper pull setup, level of course or else that can cause issues. Caman how level is the trailer behind your 400? And I'm absolutely against putting weight behind the rear axle to try and lighten the front. That's a real good way to induce some sway. What are the tire pressures running on this truck?
