Copper “noise reduction” washer in rear hub assembly

Alright, I’ve read all the posts regarding this copper washer that was installed as part of a TSB to reduce noise of some kind, and then was done away with in later models.
 
Mine are in fine shape.
 
Leave them in? Or toss them? Or indifference? I can’t seem to arrive at a consensus with what I read.
 
The one advantage to leaving them in is that the TSB says to torque the axle nut to ~120ft/lbs, which is actually attainable with my torque wrench, as opposed to the ~200+ ft/lbs required if you leave the washer out.

They were in there before, correct?

Did you have any issues or problems? If not I'd reassemble as before.

Dont break it, if it ain't broke!

I put mine back in.  I also like that lower torque setting.  Where is your seal?  It is missing from the picture you shared.  It goes in before the axle flange goes on.

Bought this car as a non running project, so no experience with it before, but everything appeared OK. Yes, they were originally on the car.

Yeah, I’m liking that lower torque spec.

Yep, I have the oil seal, just didn’t have it installed for the pic.

Appreciate the feedback.
