Took the slop out of my 400's Fast Hitch by replacing the sway limiter assembly. Both the shaft and the housing were worn. Also installed a Check Valve in the system as there was not one. The hitch tightened up considerably with these parts replaced and some TLC. The eye bolt was loose and the threads were beat up. I had a shop chase the threads on both the nut and eye bolt, good as new. I bought a fast hitch installation instruction book and it is chuck full of good info. I didn't know that there are even braces that could be installed on the sides if you were only using it as a draw bar. I plan to purchase a swinging draw bar in the future. I keep reminding my wife that this is a whole lot cheaper than a Harley!
