    Posted: 02 Feb. 2010 at 8:01pm
Wondering at what point it's a good idea to replace old leaf springs.  None are broken on my 46 but there's a some rust bleeding off that doesn't look too good on the rear.  Anyone have pictures of leaf spring refurbishings?  I'd like to be able to reuse as they still had bounce and none were broken.  I was going to give them a good cleaning and a paint job.  Any input on this would be great!  Thumbs Up

 My rule of thumb is generally to take them apart and see what's there. If none of the leaves are worn into one another, the eyes are serviceable,  and nothing is broken, and the ride height of the Jeep seemed to not be compromised too much, then I'll reuse them.
 
  I usually lay them all out and clean them very well, then paint them with Slip Plate which a is a graphite impregnated paint. Then I reassemble and use a new center bolt.
It isn't leaking, it's just marking its territory.

New USA made springs from walicks are pretty cheap.

I recently had planned to refurbish the leaf springs on my 46 CJ2A, but discovered once the springs were disassembled they were in worse condition than appeared, heavy rust, splits/cracks on the face of each leaf.  I purchased new springs front and back.

I haven't found any splits or cracks on any of the leafs, i'm just going to clean them real well and see if i can find anything wrong with them.  I'll take some pictures after i've cleaned them and post em up.

The tappered springs that are Willys originally used aren't available, so a good set of original springs are of value to the purist.
 
I'm interested in the "Slip Paint" Randy mentioned. It seems only natural that this area would have a hard time holding up in the paint area.
 
Another point about old springs is that from what I've read, that "respringing" them doesn't last long...If someones got something different here I'm all ears.

Gary,
Re-arcing spring used to be common, not anymore. I was lucky to find an "old time" spring shop who did mine the correct way (anneal the metal, reshape them, and then re-temper them) I don't think this place is long for the world though, the owner is getting quite old and had been talking about closing down for a couple of years now(says he can't find anyone who wants to learn the business, guess it's easier to buy replacement parts, or just scrap the car), as far as I know, he's the only one left in the area. He (and his knowledge) will be missed.

Here's a few shots of the springs i have to work with.

 
 
 
 
Out of curiosity, anybody know what thickness these springs started out as, i'm wondering just how much metal has flaked off as rust.

I have been looking for something just like this. Thanks for the advice. 

 

I'll have to go the route of painting each leaf individually then since i am refurbishing an old MB i would over coat the assembled pack with OD paint.

 Peter Debella has the correct return clips for a rebuild job since they usally break when they are removed.  If you have the way to press the dimple in them, (I used a shop press to make mine) they are not to hard to make.
  Your springs looks pretty good and well worth rebuilding.
 
   I have some NOS center bolts and if you need a couple I will send them to you for the cost of the postage.

 Here is a link to the company: http://www.slipplate.com/
 
  There are plenty of online dealers. Just do a Google.
 
  My local hardware store carries it in these parts.

I debated this, but decided to do restore my old ones. It's a pain, but all you have to do is take them apart, run each leaf over a wire wheel on the bench, coat with Jasco Rust Converter, repaint, grease each leaf and re-assemble. Good as new!

Thesee were really stiff springs from the factory, with lots of leafs, and WIllys are light weight, so they're probably fine to reuse.
