    So I have a 2019 TRD PRO 4R. As it has started to get colder in TN I have started hearing a dead strut sound when rolling over bumps at very low speed or thru a bumpy yard. If you have ever had an old car with a bad front strut that empty hollow thud sound is what I’m hearing. I feel like it’s a temperature pressure issue with the fox shocks. Has anyone else had this sound? I have checked all suspension bolts and components. All are tight! Any ideas?

    P.s. I know they are coilovers... not struts but I’m using it as a reference obviously..

    Are you sure it's struts? I've read where some get a noise form the sway bar mounts??

    I’m not sure where the sound is coming from but at very slow speeds crawling through a bumpy parking lot or such it’s just a sound that’s like a dead strut sounds... I’ll spray some penetrating oil on the body to sway bar mounts see if that helps.

    Spray one thing at a time if you can, that way if it goes away you know what it was.

    do not spray oil on the rubber parts. spray with a paint safe silicone on all the rubber bushings .. use home depot silicone spray . safe on paint /rubber/plastics ETC..
    petroleum oils will attack rubber.

    WD 40 is safe on rubber and painted surfaces.

    I have heard a low click sound myself from time to time on a slow roll over bumps. It comes and goes. Didn’t start happening until I had new tires installed. My center caps on the wheels are now loose and rattles when touched so I think it might be from that?

    I never used fluid film . linseed oil works to protect from rust . linseed oil is not a petroleum product organic. mineral spirits does not damage rubber plastic parts. seals.. I use mineral spirits to clean up any grease/oil .. works very good used for decades and no damage..

    penetrating oil is a bit nasty on rubber ..
    I also spray the silicone on my control arm bushings and CV boots ... looks like new no cracks/no small spider cracks rubber very flexible .

    Linseed oil is used to protect airframe internal tube frame on older small A/C's for decades.
    DuPont Teflon Dry or Wetv50 is good lube won't t deteriorate rubber too

    Have a 2019 PRO, and now that temps are consistently in the 30F's here I'm experiencing the same thing. Just curious if you were able to figure out where it is coming from.

    I just had mine in the shop for 10k service and asked them about the same thing. He told me this was normal for the Fox shocks at cold temperatures. Right now there's no "fix" but it doesn't make the vehicle unsafe just slightly annoying. Good news is Fox and Toyota know about the issue so hopefully they will be able to figure something out soon

    I have not found a solution for this yet. Thanks for the latest two posters confirming the issue. I wonder if TRD Pro Tacoma's are having the same issue?
