Old leafs

I'm running a pair of 10yr old 4" superlift leafs up front,and after removing the sway and track bar they flex and ride alot better.
The problem is with rust in between the leafs,there isn't much but every time they flex I hear a loud popping while the leafs shift.
I tried spraying them with PB-blaster lube and it worked well for about 3 days but now the leafs are barking again.
I found some PB-blaster white lithium grease and graphite dry lube,
would one of these be better suited for my application.

I think you can have them rebuilt and greased. I've restored a few old cars and wanted to maintain the original parts. I had the leafs rebuilt fairly cheap.

I think you need a thicker form of grease than WD-40. Anything short of a heavy grease will simply wash off.

Just my 2 cents....

Do you have your shackle bolts too tight? Did you tighten them to correct torque specs? Did you tighten them while the Jeep was on jacks or was it sitting on the ground with the vehicle weight on the springs?

if you're going to use any type of lube on your leaves, use the dry graphite...a wet grease or oil will just attract and hold the dirt, turning your lube into a grinding compound

I'd pull them apart and clean, paint, put in new bushings and reinstall.

Of course, it may be worth it to spend a few hundred on some new leaves at that point considering their age.

This is definitely just a bandaid,the leafs sag over 1" and ride a bit lower on the drivers side.

It's time for a new set but that's a few months away.

As far as the shackles,I haven't touched them since I bought my rig,
I just wheel the thing and fix what ever breaks.i'll check how tight they are.

Now,would the graphite be able to seep in between the leafs or does it come out as
a solid/powdery form,I've never used it before.

if the shackle sleeves are rusty they will bulge and bind in the bushings. Can get funky sounds when they break free.

the CRC stuff I've used comes out of the can as a liquid the dries to form a nice thin coating of lube

I would pull the Leaves apart and wire wheel them , the best way to get the rust off . Change the center bolt out while you're at it (I use a hard allen bolt , you may have to drill out the perch a bit ) . lube between the leaves with dry graphite , don't paint the inside of the pack ,paint once it reassembled . Then swap out your bushings to polyurethane , with greasable bolts . Do the same with your Shackle bushings . At the very least look at them like someone else said . You can shim 1 side at the perch to get your rig back level again if you need to . this is probably your cheapest fix .
just my 2 cents

REAL JEEPS HAVE LEAF SPRINGS

NO REALY ,, IT IS HIP TO BE SQUAIR

If you're getting new springs in a few months, I wouldn't do a thing except for spraying the bolts with Kroil or something similar to make taking it apart easier.
