What is the best method for lubricating spring leafs.
I've seen a wide variety of methods described here.
There used to be a device call a 'leaf spreader' available, which forced wedges between the leaves to separate them and allow you to squirt lubricant in.
The poor man's way to do this would involve banging in a pointed tool to spread them enough to insert a crowbar or something to separate the leaves.
In either of these scenarios, jack the car up by the frame, so the axle is hanging loose. This will make it easier to separate the leaves.
If you want to go whole-hog, take the springs off the car, and take them apart. Then you wire-wheel off the rust, and paint them with a rust-resistant paint. Just before re-assembly, you apply lubricant.
In that scenario, the lubricant can be oil, grease, or a Teflon-containing paint, or adhesive Teflon strips.
It is called slip paint. A paint with graphite mixed into it to be painted on the disassembled leafs prior to reassembly.
If you want to mix a batch of homemade slip paint using the original Ford formula, refer to: www.mtfca.com/discus/messages/29/19078.html, or, you can go to Tractor Supply and buy a can, ready mixed. Jim Patrick
I spray the springs with penetrating oil and then jump up and down on the running-boards to flex the springs.
Seems to work okay and requires very little effort.
