I don't know what this is worth, but mine don't look any better. Either both our springs are fine or they both have the same problem.

I took a glance at the FSM too and a lot of the drawings show the bottom leaf nearly flat.

I looked this stuff up at 1sttoyotaparts. You would spend a $1000 there getting complete springs from there and $250 just getting the lower leafs.

If the springs are in OK shape, what is the possibility that the shackle bushings are worn? There are 6 of these and they are in the $3 range.
