Is There a Torque Rating for Installing Trailer Suspension Shackle Bolts  

Question:

Expert Reply:

Since suspension components use lock nuts on the ends of the shackle bolts and the bolts need to be able to allow movement you actually don't want to torque down the bolts at all. You want to snug them up so that there's no lateral play but still allows easy movement of the bolts/shackles so that you don't inhibit the suspension from being able to do what it needs to do.
