Hi guys, I dropped the right spring off today,

What I've seen so far is, there was sideways movement in the spring between the front chassis plates, probably a couple of mm which produced a great knock when moving by hand. The 9/16 bolt was also worn down in the area of the Bush .. and shows a definite step up to where the chassis plates are. So I'll replace this bolt.
The springs don't seem to old say 5 years, and both Bushes are fairly new and tight in the spring.
The rear shackle bottom bolt is not worn at all....but atm I was unable to rotate or remove the top chassis shackle bolt, I ran out of time today but not sure what's going on there???

When I get to resemble I'm thinking to pack the play between the spring and front hanger with a couple of washers... b4 bolting the Bush up tight as John recommended .

Cheers.
