They are spring loaded. They must be used onthe front to ensure proper system performance. Priorto installing the front turnbuckles hold the turnbuckleup by the captive (non-threaded) hook, mark the hookat the point where it enters the barrel with a painted,taped, or scribed line to make future installationseasier. Install the turnbuckles on the truck and camperwith the threaded hook end up. This will keep moisturefrom entering and pooling inside the turnbuckle.Tighten the turnbuckle until the mark that you madehas drawn away from the base of the barrel by 1/4".This will set the proper preload on the internal spring.DO NOT TIGHTEN BEYOND THIS POINT! Theturnbuckles can be easily hand tightened to this point.Use a 3/4" wrench ONLY to tighten and loosen the jamnut which prevents the turnbuckle from twisting loose.Happijac Rear Turnbuckle InstallationUnlike the front turnbuckles, the rear turnbuckles donot have an internal spring.
