Best lube for squeaky leafs?

Also made sure U bolts are tight, mine came from factory ~30PSI (EDIT FTLB... was playing with a compressor today haha) and they were very squeaky, now at ~60 and quiet.

 

This too.

 

I use the Lucas Red and Tacky. It comes out of the can as aerosol and then sets up into grease. I used a wedge (screwdriver) to spread apart the leaves that were touching and spray the hell out of them.

No squeaks so far.

This is what stopped the squeaking on my Dakars and I've found it to be the best solution. No grease or oil needed therefore dirt doesn't stick to it. They also don't require frequent maintenance to keep them silent, they just work out of the box and will continue to work.

 

Do you need to disassemble the leafs to install these or can you get in there with a pry bar?

 

I had mine in for the TSB for the squeaky leafs, can't remember what the dealer did, but it fixed it permanently.

 

This with the stock springs?

 

You just need to lift the truck and let the suspension droop fully. Pry bar works great, oh forgot to mention that the dorman's mounting post is too long to be used as is, I used a hacksaw to cut them to about 1/4"-5/16" tall.

Here's a photo of how they look. 12k miles and they're still holding up, the only "maintenance" I do on them is blast them with the hose during a wash.
