TV vibration transfer to trailer

I have scoured the threads, but haven't seen any specific info on anyone having trouble with their TV transferring vibration to their AS (i.e. causing rivets to pop/shear, partitions moving/rubbing). Does anyone have any advice on how their TV performs regarding this specifically whether a 4x4 vs, 4x2, is better/worse. We have a 2000 Ford Excursion 4x4, 6.8L-V10, 3.73 axle. We have noticed some vibration issues and rivets popping. Would the radius rods mentioned in other threads, and or sway bar help this issue. any help would be appreciated.


Thanks,
Mary

There are past threads about this issue. The ideas out there are 3/4 ton and full ton trucks transfer more shock. Some fixes are: air ride or air safe hitch, replace tv rear springs with air bags or take off the helper spring, reduce tv rear tire pressure. All of these ideas have the goal of creating a softer tv rear end .

It is also possible your rivet popping, etc. is related to shot axles.

Super heavy duty trucks cause the rivet problems, along with excessive rated hitch bars.

Lack of proper running gear balance on the trailer, improper rear tire balance on the tow vehicle, along with bad axles can also contribute to the same problems.

Combining some of those causes, leads to exactly what you are seeing.

I tow with a 3/4 ton 4X4 and had vibration problems with the trailer. It got solved when during the change over from discs to drums I had the trailer tires and wheels balanced.

Great info, keep it coming

Thanks, we are planning to get the wheel bearings done and will have them balanced too. The PO told us that the axles were fairly new, so I don't suspect them. We are the AS 3rd owner. The vibration is not earth shattering, but enough to want to look into options of how to fix it.

Mary.

Most dealers can only balance a tire and wheel.

That leaves the hub and drum unbalanced, which is usually the culprit.

You can install Centramatic balancers that solve the problem, permanently.

Many semi trucks use them as well.

Andy,

Where can I get these Centramatic balancers installed? Do you guys do that at Inland RV? If so how much would that service be? Or do you sell the part so I can have the tire people who do the wheel bearings put them on?

Thanks, Mary

Mary.

Anyone can install the Centramatics.

All that it takes is to remove the wheel, slip the balancer over the studs, and remount the wheel.

We cannot quote prices in our posts.

The Centramatics can be found at many good tire stores. Some folks have had a bit of a problem getting the right ones to fit in the spacing so make sure you can test before committing. Alternatives are 'in tire' balancing beads which do the same thing but need care whenever changing tires.

I have towed with cars, vans, and now 3/4 ton superduty. I dont have any issue's of rivits popping.

I have a buddy that has your exact setup ( excursion) he tows a 25 footer. No problems there either. I like the heavier tow vehicles, because life expectancy, and, I really dont even need torsion bars, or an equlizer hitch.

I do use the lightest bars I can find for my reese set up, because the heavier trucks ride smoother under a load. My rig is level, and doesnt sway. It isnt even on the helpers when I hitch it up.

If I had a catastrofic failure. Brakes, torsion bar, or high wind, icey or wet slippery condition, I want extra weight on my drives, and my tow vehicle heavier then my towed vehicle.

You might have a belt slip, or wheel out of balance on your trailer. Maybe even a bent rim.
