I have had 2 of the SingleTrail vertical racks now, a new one and a V1 which I just sold, the anti wobble on both is a sophisticated work of art, its awesome. Even more so on the new V3.
But...
Just as good and works 100%, I used this on my ISI for nearly 10yrs and still have it, a rock solid way of stopping wobble.
Get yourself a 100mm bolt that fits the hitch hole and nut, weld the nut to a piece of plate that fits up yer 50mm hitch. Forget about adhesive.

Fit the plate to the inside of you hitch. As per number 1 into number 2.

Line it up with the hole you require for your car, missus car, mates car etc....
Poke a stick welder in there and tack the fucker in place
You could even wind the bolt in to hold it in the right place to get the outside tack in place, then remove the bolt and poke the stick welder through the bolt hole to tack the inside.
Next is to work out how much of the thread you need to just go through the nut plate and car hitch thickness, then grind the excess off. This is wasted threads that you do not need to be winding in every time you fit the bolt.
See mine after 10yrs of use and about 100,000km behind vehicles and on a caravan.

Drill a hole big enough to fit a padlock to.
When the bolt is tightened, it pulls the bike rack tongue against the hitch side wall and its never moving. I even had a cheap ratchet with the correct socket in my 'hitch roll' that stayed in the car.
Cheap, simple and 100% effective.
