RE: Front sway bar broken - DK on the road - 09-13-2021

So, this morning I retied it up with bungee, and several independent 10g wire double wrapped loops around it.

BTW, this is an 1 1/2" swaybar, no upgrade available. "3 or 4 broken Swaybars does not make a problem requiring an up grade" (newell parts)
about $1,100 after ground shipping

RE: Front sway bar broken - DK on the road - 09-13-2021

(My coach has something like 16,000 pounds on the front axle. The anti roll bar is resisting a huge force in these coaches.

Bend any steel enough times and it will fatigue fracture.

I view all springs as a wear item that will need to be replaced from time to time.

If the size of the anti roll bar is increased too much then it will compromise other aspect of the suspension. Too much resistance and the other pivot points take on too much load or the system just binds up, becoming non compliant. Too stiff and you basically have no suspension and the tires leave the road.)

I respectfully disagree with springs and bars needing to be replaced as a maintenance item. I'll just say I have an extensive history on all kinds of automotive (including a race car team for road courses) and Trucks, particular Class 8(owned and managed a fleet of Semi trucks), including Motorhomes. I have never had a swaybar break. I have had suspension components break on Semi trucks, mainly due to overloading and once to abuse off-road. Never over the road, normal anticipated designed usage. I treat this Coach as an Asphalt queen, Unlike Semi trucks, where they may get used off-road as a dump truck. I'm not going to make a case against Newell, but I've only got 108K on this coach. You are correct, these are very top heavy vehicles and that Torsion bar is trying to control that motion and its not easy to do that. Engineering can be better, either mechanically or environmentally.

I just would say, the lateral bars could be shorter, angles could be different, diameters could be bigger, or my tax dollars could make better roads.

Now finishing my trip without the swaybar, adds stresses to other components and that's where real trouble begins and I'll have to take it very easy.
