Sags to one side

[410Fortune]

I know what the j hook does silly
I was getting at the fact that your coil buckets are not stock. They look to be the stock bits re worked a little. And the stock coil buckets have an indent where the end of the coil spring must sit for the truck to have correct ride height on both sides. To me in the one small pic we have of the coil bucket your coil does not look seated in the correct position which will throw off your ride height
So some more pics of the coil buckets from both sides could help sort that out

You can swap leaf springs left to right see if it still leans?
Unhook rear shocks and drive it a little
Still lean?

Your giving me ideas now, and it still leans swapping both leaf springs but not as bad making me think they are both worn out I just don’t have a lot of experience with deaver, and I’ll look up the coil locations see where I need to have mine set. just the driver rear side has the dip I can lift that side barley and it will be even just settles with a sag

Deaver makes good stuff, but I always thought their Explorer leafs were too soft for the weight. Anyone who builds a Explorer with some go fast shocks is going to beat on it so it's very possible they are shot.
