leaf spring inspection..what to look for??

Wow! a 1000hp engine and transbrake and you need help with what to look for on leaf springs?
OKAY
1) Look for wear and cracks in all the leafs or twists.
2) Make sure the center bolt is tight and not worn.
3) Replace the end bushings if cracked or mushroomed out. Look for excessive spread at the eyelets.
4) Dependant on if you are allowing the springs to "fan" when loaded... replace the spring pack clamps.
5) Always use new u bolts and nuts. Light oil when tightening them.
Good luck. When in doubt- replace them. You've come this far.
