I have used petroleum based grease on my pins forever (decades) and have never had any serious issues with that grease swelling up the rubber components, until recently with a Chev van. I had to replace the boots and the rings around the pins as they swelled up and caused all kinds of problems. Started using the silicone on this vehicle and have found that silicone can gum up way faster than petroleum grease, even if it does not swell up the rubber parts.
I believe it depends on what type of rubber/compound the boots are made of. Natural rubber definitely cannot take petroleum jelly, other rubber compounds can; when they can, I find petroleum grease works much better. If you have to use silicone lubricant, check your pins frequently (at least every six months).
