Can anyone explain this to me?

 

Front or rear? Where did you see this requirement?

 

Front. I have read in a few places that its important that it "bottoms out"
Maybe its my english that is bad?

It has to go in the hole on the spring perch to keep the springs from moving around. Think of it as a key way!

I think it would be important that it does NOT bottom out, it would be holding the springs off the axle. It does need to have a decent amount of the head in the hole, it has to resist shear forces. Can you point me to somewhere it says this?

 

This was the first one I found, post 7.
But I belive i have seen it on MF home page somewhere aswell

Of course no I can´t find the first source that gave me this headace. But when googling the centre bolt it more or less just confirms what you all ahve said and what I felt as more logical, that it shouldn´t bottom out just centre and guide the spring onto the axel during mounting and keep the shims in place.

But is I stumble onto the source again I will post it here for further discussions.

 

If you are talking about this statement:

"I also extended the spring pack bolt to make sure it was landing solidly in the axle."

They meant it has to extend into the hole enough to keep the axle from moving around. When using the shims (wedges), to change the caster of the front axle, you have to make sure there is enough bolt head to pass through the shim and into the axle hole. As was stated before, it shouldn't bottom out.

 

Or it could have been making sure that the bottom leaf 'bottoms out' against the axle. Not hung up on the bolt head. That would be bad....
