Default does trailer need to be jacked up to add grease to bearrings?

What are everyones thoughts as to the necessity to jack the trailer to spin the wheels while adding grease to the bearrings? I have the tiedown superlube spindle system, and have heard about 50/50 split opinion as to whether or not you need to jack the trailer while pumping the new grease in. Will be my first time doing this so thought I would get one last set of opinions before deciding haha.

No. You are adding grease to the void space between the bearings which is causing grease to be forced out through the voids in the bearings at probably all places except for where there is contact with the bearings. However within the first 10 ft of rolling forward those places on the bearings are going to pick up grease from the other areas that were greased.

Depends on which hub spindle cap you have. If you have the non- buddy bearing spindle rubber cap with pfister fitting in spindle nose you have to spin as you pump grease in cause the ole grease comes out sides o spindle where you are pumping

Adding grease is not a substitute for repacking.

Back when trailering long trips, I would jack up the trailer just to spin the wheels and listen to the bearings. It is an easy way to check to make sure they are good to go. A rumble sound meant corrosion and a failure was looming.

I have the Tie Down Vortez hubs and they do need to be jacked up so I can spin the tire while adding grease. It allows all of the old grease to be pushed out.
