First you have to know what is making your combo have chucking.
A truck/GN or 5th wheel trailer can have chucking for several reason regardless of hitch brands. And even some have had the issue with a air ride type hitch.
Now having said that.... a individual may do something to fix one of the many reasons for a combo to have chucking problems and it may work for his combo.
My point is what works for Bobs combo usually doesn't work for Joe's combo.
