I have 2015 Cardinal. I understand there might be a grease zert to add grease to wheel bearings. I'm from the "old school" days when you had to disassemble entire wheel assembly to clean and add new grease. Can someone that has actually done this give me a heads up on where this zert is and what is involved to get to it.
I am same as you with the breaking down and cleaning the bearings and such. I have a 2016 Cardinal that came from the factory with street side bearings and wheels in great shape but the curb side had way too much grease in the wheels that they had to replace brakes and housing. I never skip on pm.

Don't use those zerts. They were set up for boats without brakes. Why they put them on a big trailer l will never know. You can very easily blow right thru the grease seals and end up screwing up your brakes. Just take the wheels off and repack by hand . That way you can visually inspect the bearings and races.
