I bought a cattle loader on eBay. It bounces great till it gets to the doors. Then it kind of sticks and the next one knocks it over. I found a manual online and it said to grease front of cows. I have sewing machine grease which I’m sure will work. Manual said front edge.
I would nominate this as one of Lionel's worst "operating" cars. I had one from the LTI era. After fiddling with, & trying to adjust, it for like 2 years (including one time sending it to the Lionel Service Dept.) I just sold it. I've never heard of putting grease on their felt bottoms & don't see how that would help.. .only create more drag.
