Extremely interesting gents, i'd figured that in the dawning days of the leaf spring animal fat/oil must have been the only option. Thanks Button that's reassuring to know that you have achieved full penetration using a similar method to myself. I shan't dismantle my equipment at this juncture in order to verify, but a further question! Is it possible to change the u-bolts holding the leaves together, one at a time, with the whole set up insitu. My thoughts where with one u-bolt off increased penetration may result. The other issue is that have some of Peter Mulberry's super extra strong (?) U-bolts languishing on my shelf whjch might be nice to put into service
Not sure if this will help. When I was a young 75 I would remove the springs, take them apart, clean them, paint them and apply axle grease between the leafs. Somewhere I learned about Chain Oil and use this system. However, one must drive their Morgan to work the chain oil in between the leafs. Now that I am 89 going on 90 just bending over or crawling under a car is almost impossible. But so far I have driven the spring over 3,000 miles and in July expect to do another 3,000 miles on a trip to Southern California. Loctite sells Chain Oil in a aerosol can, using a plastic straw I can easily apply the chain oil. I must remove the cover on the parcel shelf and the rear tire for access but with little effort I can get the spring covered with the chain oil. It ain't "rocket Science".
