I need to pull out the bearings to clean them and then regrease them before we use our POD, still have two big projects to finish before I look at the POD. I have not thought about what grease to use so I thank you for your leg work. I believe what I would do is to clean the old grease from the bearings and repack them by hand with the one brand that you can get then repack the grease gun that you want to use for the bearings by hand with the rest of the grease in the tub.
We traveled right around 3000 miles last year with the POD so I will spend the time and a few dollars to repack the bearings to prevent a failure on the road. Before we left last year I did hit each bearing with the grease gun using the grease that I had in it, making sure that I had grease coming back out through the bearing. On our trip I checked the bearings at every stop for excessive heat and they ran cool the whole way. Goose
