I have had nos springs apart that were set up for spring lube---no grease inside

I had a 46 that the springs were greased---rode bad
had a 39 that always had spring lube---rode very well
spring lube is very thin oil---and talc, the talc is a polishing agent and dry lubricant----its in slip plate products
The service bulletins in 36 told about the new method, that a dedicated grease gun is to be used, that spring lube was to be shaken before used

if grease has been used it fills the passage formed in the top of the spring leaf get filled near the centerbolt then coming out near the center not flowing to the tips of the leaves----once there is grease it blocks the passages from gravity flow to the tips where the lube is needed

The original formula is ---77-1/2% ice machine oil, 20% talc, 2-1/2 % pulverized asbestos -------so today we can use auto trans fluid, talc and graphite
