trailer question

[bulletbob]

If the springs, u bolts/plates and shackles are covered in rust, but are still solid here;s what I do.. Clean the excess flaking rust off with a wire brush, and then hose them off with a garden hose and let dry.. Now you can do a few different things,, You can use heavy motor oil, grease, trans or gear oil,,, anything wet and slippery that will hang on.. WD 40 penetrates well, but is gone in a few days.. I oil between the leaves, and all the nuts and bolts.. Everything really gets oiled or greased, and my trailer parts last for decades..

If you would rather not deal with oil/grease, simply clean everything well, and paint with black Rustoleum.. EVERYWHERE!.. It works very well, and lasts a very long time, and does stop rust pretty well.. If your springs , shackles. U bolts are not strong and solid, probably should replace them first, before greasing or painting everything down there..If you don't know how to tell, ask someone that does.. Any decent auto mechanic will know if they are still serviceable.....
Once you know the spring parts are solid, and you clean and grease or paint them,always wash the trailer well wish a hose, including the wheels, axle, springs, lights, rails, everything, each time it sees salt water.. Takes a minute and your trailer will last forever... When you see rotted out trailer axles and springs, its simply a matter of neglect.. I never have had corrosion problems because I kept the trailer clean, free of salt, and either greased up, or painted, or both.... bob
