I do ‘We recommend injecting more grease into new bearing to increase
service life, especially in wetter climates‘ from the start, then remove, strip and put them in a sonic cleaner with some jizer, re-grease put back job done. Usually change for new(on pivots) every 18 months but my hope BB bearings have been going for a couple of years using this method. Someone will be along in the minute saying that this is ‘all wrong and they will fail because you have damaged the seals buy removing them‘ FFS
