When I travelled on October 15 & 16th to Lebanon Valley, I noticed my trailer was tilted slightly to the left,. I did'nt think much of it. While I was driving home I kept hearing a loud banging I pulled over twice to check to see if my car came loose.
It did not, but when I got home and unloaded my car I looked underneath and found out my left rear leaf spring 2 center leafs were broken and I had severely bent the main spring. The loud banging was the axle tube bottoming out on the frame. Now I decided to order all new springs, equalizer kit and bolts with grease fittings. When I changed the Bad leaf spring I found that the bolts, the shackles and the equalizer all were worn. 
Now mind you this trailer is only 2 years old!!! I know I have an inexpensive trailer but this could of been very severe. Same with the brakes these also were checked and all are working due to my changing the magnets on the electric brakes earlier this year. The Morale to this story is to check everything now before you put you trailer away because you don't want to be waiting until spring to find out you missed a race or worse you've broken down on the side of the highway in the middle of nowhere.
