I have tied my quad down by the frame/suspension and I have tied it down by the wheels. There are advantages to both. But recently a mechanic that I trust suggested that securing the quad by the wheels was bad because the motion on the road was causing the suspension to move and flex similar to actually riding the quad. This puts hours and hours of wear on the suspension components wearing them out quicker. I trust this guy and I trust his opinion but I wanted to see if anyone else had an opinion on this.

Keep in mind I don't want this to turn into a debate over who has the best or coolest way to tie down their quad. We'll have that thread later I just want to know about the effect on my suspension before I make some mods to my trailer that could be worthless if I stop securing by the wheels.
