suprz seems to have one solution but it seems that his link won't open for me so here is a
clicky that may work better.
He did make one point that is very important, is to have a good anti wobble device you need one that works and will not come loose.
You need a good anti rattle device so you don't get so much play in the receiver,thus magnifying the movement and doing damage to the receiver.
I have tried almost every Anti Rattle device on the market, most have been no good or so complicated and cumbersome that they are useless. Including the Roadmaster type,totally useless.
Until I found the one at Hitch Rider.
Their
Hitch Vice is the best and easiest one I have come across and it really works.
