Best bet is to get under the slide and see what you can see. On my 373RD, the small slides have three rollers and my big slide has two rollers. Look at the material that covers the bottom, that will give you a clue what rubs/where. I think my big slide has three slide bars underneath. I use slide seal lube underneath to keep things sliding. Also make sure you lube side and top seals both inside and outside.
