There are 4 bearings (1x 6902, 2x 2214 and 1x CSK30P) inside and it is possible to add 2 extra 6902 bearings (or one wider 3902 type) on the nondrive side and one 6902 into the spider with removed dustcaps. So 3 extra bearings made 7 in total.
On the non drive side you can add these bearings easely, by removing the dustcap.
For the drive side, you must remove the spider and insert the bearing instead of the dustcap.
Because the dustcaps are removed it is advisable to use endurance bearings, thas has an improved water resistance.
These extra bearings are only for minimizing cq preventing the play of the axle.
The main reason for breaking the spindle are the circlip grooves and the low quality of the used steel.
