My relentless pursuit to cure trailer sway - the dancing TT

While I not an engineer , one of the components of sway is weight transfer, this could be from tire sidewall flex, or soft springs.

I've been driving Jeeps and now a Dodge truck, but a front solid axel will not steer on the highway as well as an independent. As brilliant as the geometry is. So the OP was wise to fix the front end.
