Straightening a Trailer Axle Part 1 

I did the same thing. But I fill my tanks up with water.

i measured from the driveway to bottom of axle its 7.25 I had a thought maybe I could put a extra axle u bolts and plate the and just have them just a little tight so the flat plate is at the bottom of axles they are only like 4 inches wide and then put jack under that flat plate just to distribute some of the pressure of the jack

What is the purpose of using the chains rapped around both sides of axle like you showed in part 2?

Did it do any damage to the leaf springs or the bolts that hold the leaf springs like bend them ?

What size boards did you use a 4x4 or 6x6 ? one of my front axles are bent the top is leaning in a little i had a thought of using like 3 or 4 mufflers clamps on the bottom of axle to hopefully keep the axle from crushing in and use the boards like you have yours i do have a 3 ton jack on wheels but by the time you put jacks and 6x6 or 4x4s under it i think I would have to have trailer really high what's your thought ?

How did you tie chains down ?
