People repor good results from removing the 1st and 3rd or 2nd and 4th spring from the bottom...better ride...though it lowers carrying capacity. Leaves are removed at all corners.
A springover wont change the ride much by itself...
Taking the leaves apart and cleaning them and painting them with slip-plate helps a lot.
Have the shackles been greased recently? Are they working front and rear the way they should?
I know the stock suspension isnt smooth...but "car accident" seems like something is wrong.
Lord send your Holy Ghost into our hearts and make the desire of our hearts Your Will.
Pro-choice, that's a LIE, babies don't choose to die!!
