Just not to be understood wrong - I have used WD-40 (or whatever similar) to facilitate the penetration process, not as a lubing agents. It also was an important moment to analyse where from the squeaking comes from. To locate the squeaking source is sometimes quite difficult. I have disassembled several times the front covers of the leaf spring mountings, as it sounded like a rubber squeaking. Now at least I know it is definitively coming from the between the leafs. I have applied now "Fluid film", which stays "live" and does not solidify as chain spray does and has not bad lubricating abilities. It is also very resistant against water, as it was originally developed for floating ballast tanks of ships.
In the old times, I remember the bikers did not relay just on the chain spray (they always said it stays just on the surface). They "cooked" their chains in hot oil once a year before the saison. Nowadays, the bike chains have on each member O-Rings, so the chain lube does not have any chance to get in. In fact, it protects the chain from outer wear only. So, depending on the individual car and its squeaking character and source, probably chain spray works in the most cases, but not always. Those cases needs an individual solution, maybe a combination of different treatments.
Of course, definitely the best solution is to pack the leaf springs as DaveW described. However, with a lot of difficult work.
