Low Frequency damper

I have to replace my rear calipers and wondering if others have replaced the low frequency noise dampener on the rear wheels. Is it beneficial to leave them on there? My remanded calipers come with new bolts and I was considering just using the bolts, mainly because the damper is looking a little rusty. I haven’t tried to see if I can easily get replacements. I see that they are available from Rockauto, but I want to do the work soon and don’t want to wait. I could just put the old ones back on, what does everyone think, when is it time to replace?

2010 F150, as noted in my profile. Here is a picture. I saw some YouTube vids where they utilized these on newer F150’s that did not originally have them.

Hmm, I have to admit, I've never seen anything like it before. My truck doesn't use them I know that. What I did find is they only used them in 2010-2011 and have quite the aftermarket following for availability. I'd say leave them off and if you notice any new low frequency noise, put em back on.

Looks like something you would put in an expensive luxury sedan, not a pickup :lol:

This is a luxury vehicle 😬
