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?

 

What are you working on? I've never heard of any such dampener on the rear wheels, perhaps take a pic so we can get a better idea what you mean.

 

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.

Low frequency noise damper

 

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.

 

I went ahead and put them back on, even though they are a bit of a pain to remove. You basically have to use vise grips to remove them from the special bolt. Then you can use a socket to remove the remaining bolt. They aren’t hurting anything and maybe they actually silence some unpleasant sounds.

 

There is no need to take them apart. Just loosen with 10mm open end and slide the dampener against the leaf, then tilt the caliper up. It just has to clear the threads in the caliper.

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

 

I think the open end 10mm wrench just trys to round out the nut. Vise grip works okay to loosen and then use a end wrench.

This is a luxury vehicle 😬

 

My truck isn't rust free but the hex was in good shape. A flare wrench or vice grip would work great too. This is not meant to be torqued too much either.

I agree, my platinum interior can give many Lux sedans a good run for the money,. Heated rear seats :lol:
