Hello gents, I just wanted to document a quick and easy project I undertook today on my 2020 F350 CCSB 6.7 truck. I drive around with a pretty good load of tools/parts/ and bed tank fuel in my truck on a regular basis. I’ve come to notice some squeaking coming from the rear suspension. I did the following on my 2016 F250 back in the day and it worked like a charm.



There are nylon pads at each end of the spring leaf that wear over time. When they go long enough, you wear through the pads and metal on metal begins to squeak. Dorman 924-070 is a kit with 4 new pads. I lifted the truck from the hitch receiver to unload the springs as much as possible. Then using a couple of pry bars and a narrow screw driver to get started spread the leaves to remove the old pad and popped in a new one. DON’T EVER GET YOU FINGERS BETWEEN THE LEAVES. If your bar pops out you’ll smash your finger. I used a blunt punch to pop them from the hole and used needle nose pliers to slide the new ones into place. Once they’re lined up removing the bar seats them

My F250 needed a set of 4, the extra leaf on my 350 needed 8. I bought the same set of 4 from Amazon I purchased in 2019 before I even looked under the truck this time. Luckily the second leaf pads hadn’t worn through yet so I rotated them 180degrees and put a dab of dialectic grease on them and the new ones too. If you don’t have a squeak yet it might benefit you to add a spot of grease to the pads to smooth out the ride and extend the pad life.



Good luck!

 

Grease the pads while you are at it with a waterproof grease.
Makes a HUGE difference.

 

I read if you grease all that area between the leafs it rides better too.

 

I’d read that too. When I did my 2016 I didnt grease them, but did this time. Night and day difference, obviously the noise is gone but smoother too.

 

If you don’t want to go to the aggravation of greasing the entire leaf use motorcycle chain lube- the kind that sprays on thin then thickens up- it will wick between the leaves.
