During the install of my new CityGrips, I noticed that the bearings had a slight lumpy feel as I rotated the front wheel, so I ordered a bearing kit from Allballs. A whopping $12 shipping included. I noticed that the kit included 2 grease seals, but upon removal I noticed that there was no seal installed on the speedometer side. The side with the grease seal looked like new with fresh clean grease throughout the bearing, and rand smooth. The speedometer side was dried out with a brown waxy residue all through the bearing, with a rough lumpy feel, definitely worn out. The question I had was should I install the grease seal on the speedometer side even though the parts diagram does not call for one? There seems to be room for the seal.
