HELP! I'm running out of ideas

I think it is most pronounced on right hand turns, but I think I felt it too on left handers, just not as bad. The rims up front are 14x7 with a 4" offset with 205/70R14 tires. I have driven them without issues for years and they aren't rubbing on the fenders or frame. Late last year the problem suddenly started.

I had bought hotchkiss leaf springs a few years ago (1" lower then stock) and when I installed them the passenger side rear tire would hit the hump on the inner quarter panel. I found out the current rims on the back are the wrong offset (15x8.5 rim with a 4" offset and 255/60R15 tires) pushing them out too far. I've ordered new rims (18x8 with a 4.5" offset for the back and 17x7 with a 4" offset up front) so that should solve the rubbing issue out back.
