Surprisingly, these bolts are not on the MoCo's critical fasteners list, but they seem critical to me. I wonder if they consider re-torquing more detrimental than just leaving them as is.

Do you re-torque yours? Is so. How often?

 

 

I have permanent Sharpie marks drawn thru my pulley, washers and bolts. If any part of the line doesn't "line up" I know something is amiss.

 

If they are loose enough to need to be re-torqued, you need to replace them. Do not reuse/re torque rear pulley or brake rotor bolts.

 

 

Rotor bolts can be reused up to 3 times according to the service manual, now before anyone starts flaming me that is listed for some years and not for others so follow YOUR manual if so inclined. Think about it this way the bolt is steel, the hub it threads into is aluminium. Which is more likely to get damaged from repeated torque? Do you replace the wheel every time you install a new chrome rotor? HD wishes you did.

Just my thoughts

 

When using rotor bolts that have the factory dry loctite, I think the stretch occurs when you loosen them. My manual calls for replacement but even if it didn't, I'd still replace them. The price of failure is a swing arm and a locked rear wheel. I don't know if I'm right so I error on the side caution.

 

And new bolts are cheap, I don't disagree with you. Just seems to me the aluminum threads would be the weak link?

 

That certainly sounds reasonable.

 

If they get loose its likely already messed up the hub.
