Leaf springs squeaking

Noticed it about 2 months ago. rear end will squeak when going slowly over a speed bump.
I didn't do anything suspension wise. Truck has been parked more than usual at my work while we are renovating garage. Grease the leafs ?

 

I spray chain wax on my shackle bolts, seems to help.

 

When installing the Icon pack I used chain wax. There's been no squeaking or dust retention. It's probably something I should do yearly.

 

I started having this extremely annoying squeak also! Drives me nuts. It started after a resent trip out in the sand dunes so I'm guessing that was the issue.
I tried jacking up the truck to open up the leafs and used a power washer to try to clean any dirt or sand out. Seemed to help but did not go completely away!
I used to use WD40 on my Tacoma because those springs got so bad but feel like that was worse n attracted more dirt. So now I'm scared to try anything on my new tundra. For now the noise is almost gone but I have not done any off-roading lately. I can't imagine other tundra owners living in worse climates like snow n mud all the time and not having any noises. Might try some of my motocross chain lube.

 

Seems to work the best out of WD, dry lube, Tri-flow, and the pressure washer.

 

I sprayed my leafs with this Maxima chain lube I use for my dirt bikes. All squeaks went away and it's been over a month with still no noise! Super happy it worked. Thanks for the
tips! Hoping this can help anyone having this issue in the future!

 

Found this thread and it saved me! Crawled under and sprayed my leaf packs with Maxima Chain Wax, and bounced up and down on my bed for a minute or so.. once the spray dried into its “waxy” form, all creaking went away.

thank you!!
