Creaky Leaf Springs fixed in record time

I upgraded my toolbox today with my first cordless impact wrench and a proper (3 ton) floor jack.

I lubed my OME Dakar leaf springs in record time. No more creak! What a treat. How have lived so long without these tools?

My next (much larger) project is my winch bumper and winch installation whenever the bumper shows up.

 

For those wondering how to fix creaky leaf springs, this was my method.

1) Jack the rear of the truck up by the diff so that the tires are about 5” off the ground. YMMV
2) Let it down on jack stands (6-ton preferable because of height) placed under the frame. This extends the leaf springs and separates the leaves.
3) Remove the wheels
4) Spray lube between the leaves whereever there is a gap. I use Boshied T9 but other lubes will work.
5) Put it back together.

The key is extend the leaf springs and to a lesser degree get the wheels out of the way. I’ve been lazy in the past and tried lubing the leaf springs with the truck sitting on the ground and had bad results.

 

Can you elaborate on separating leafs?
Every add a leaf install instructions state that should no gap between leafs

 

There’s always a gap at the ends especially between the overload leafs and the ones above. But I didn’t actually measure any gaps jacked and on the ground. It’s possible the difference is more due us getting the wheel out of the way.

The only times I’ve had success ridding myself of the creak has been when jacking the truck up and removing the wheels.

If I get bored maybe I will try figuring out which leaf springs need the lube the most.

EDIT: the gaps I am referring to are towards the ends of the leafs. There are no gaps near the u bolts and probably no sliding which causes the creak.

 

How long does this usually keep the squeak at bay? I’ve heard conflicting info if lube is detrimental in the long run as it attracts dirt and grime which is the cause of the squeak. I’m thankful mine are silent So far. Knick on wood

 

It will likely be creaky again after take it out in the dirt next weekend.

 

Penetrating lithium grease seems to work best. Made by Blaster and others.

Like expanding foam, it applies and seeks like liquid then quickly expands into a foamy grease for long lasting effect.

While lubing, have someone bounce on the rear bumper due to the speed it expands into foam. You will want to work into place while it's still liquid.

 

I use Lucas oil Red N Tacky

That looks good.

Thanks for posting.

 

I use Motul motorcycle chain lube. Sprays on really wet and flashes off into a very thin, sticky grease.
