Washer/bolt on backwards for one.Possibility of Poly bushings that are to thick??
Here is what it looks like with stock rubber bushings
Hear is a reproduction front spring bolt with stock rubber bushings
The factory idea was the bushings will compress and suck the washer tight in the spring pocket hole,poor design at best.If you add Energy suspension poly bushings to this with stock mono's the bushings are much harder than the rubber and the bushings will not crush and allow this to pull up properly.If the bushings were 1/8 each side thinner they would work very nicely.The Engery bushings work perfectly with the CBR multi leaf springs because they are 1/4 narrower than the original mono's.
The washer is supposed to be attached to the bolt and it is slightly tapered and should fit tight in the hole.The bolt goes in from the rocker panel side.If you have movement it will whell hope something awful.Hopefully the hole is not opend up.
