Leaf Springs - How To Tidy Up?

try calling King Springs @ Molendinar ( Ashmore) on the Gold Coast. They are good guys and would probably have something they use.

If the leaf ends have worn small 'ledges' in their neighbouring leaves it might be worth putting a bit of a radius on the ends of each leaf with the grinder. This will help them move smoothly against each other.

I've just cleaned up my front spring packs and gave them a spray with white litium grease before reassembly, just to add another to the list of ideas :) Good luck mate
