Hey guys, I have about 11,000 miles on my 19 and I have a very bad squeak in my rear leaf springs. I can hear it from inside while I’m driving. Haven’t done any serious off-roading yet but I have gotten in some dirt here and there and a little mud. Noise started at about 9500 miles.

I lifted the body up onto a floor jack so the springs would decompress, power washed them out , even in the bushings and in between the leafs. Sprayed wd40 to get the water out. Hit it with a deep penetrating lube on the bushings, then sprayed fluid film on and in between the leafs and on the bushings. That lasted for a couple days and now it’s back squeaking loud again.

I’ve seen Gen1s be fixed by maybe ansoil hdmp? I tried fluid film as it’s also a lubricant and protectant but it didn’t fully work.

Has anyone experienced this or do they have any solutions ?

Had the same thing after a good mudding trip in my 2018. It lastest a few weeks and eventually went away.

I had the exact same issue and it took a desert run to shake it all out. Absolutely no squeak now. But it did come from the leaf spring bushings.

Had the same issue after TRR from a muddy day on the track. Did the same thing and it still squeaked like hell.

The fix is Red Tacky Grease in a can from Lucas Oil. Jack the truck up and apply especially to metal friction pads on upper leaf's and all the points you mentioned above and the noise will be gone.
