Gravity wagon to running gear attachment

Picked up a fairly new Unverferth 235 gravity box with 10 ton running gear. It had been bolted on all 4 corners but whoever did it drilled on an angle so the bolts came out close to the bottom. All 4 corners have the wood split near the bottom. About 1/2 of the wood split.

There are also holes further up that will go through the angle iron which is where we are going to rebolt it.

There is a sticker on the box to bolt all 4 corners and ensure they are tight. Im thinking this is what caused the wood to split when it tried to rock.

Is bolting this in all 4 corners the proper way?
 
I bolt the back, and run a chain around the bolster and the stringers in front, for the rough ground one encounters, i give it about 4-5 inch's of slop! Not saying it's the right way to do it!
 
All our gravity wagons and flat rack hay wagons were bolted at one corner and chained with some slack to allow flex between the wagon and its running gear. Never had a problem, never broke a bolster , never tipped a load.
 


You know your ground. Grain ground is usually fairly smooth and level compared to hay ground so the manufacturer's
recommendation should be good or smooth ground.
 
We only ever bought one new one. Bought it with the running gear. Back then, the dealer said to just chain it down on one corner.
