I think you would only need to replace the seals but Id probably order the bearing and races also. I just redid mine and was sent the wrong bearings. One fit, the other didnt. Bass Cat overnighted the correct ones but Id have a backup plan if planning a tournament. I had a hard time finding anything locally, couldnt believe it.Besides the mess, its easy to do with the right tools. I went and bought a race/bearing driver kit for around $25-$30 and its well worth it. Last edited by C130 on August 21st, 2016, 9:14 pm, edited 1 time in total.
