Templar 250 (not X or M)

[Maiville06]

So I tore the front off. When I am going over a bump or driving around at my house I am hearing a creaking sound. From where I can hear it is the lower steerhead bracket. I took it all apart the bearing is well packed with grease and so is the upper. Put all back together and still hearing this sound. Does anyone know what size bearings these are? Only thing I can think is to replace bearing and seals and see if that fixes my problem but I have no clue how big the bearings are other than top is smaller than the bottom one.
