The needle bearings are the same in the relay arm (boomerang shaped linkage) and the connecting rod (U shaped link)? I lost a couple of these over the years in the midst of lubing my suspension. I could not detect any excessive wear as a result of running these bearings short one needle. I confirmed with my dealer that they do not sell the needles ala carte. In stead of replacing each bearing I was going to buy one to replace the three missing needles. Right now I have the swingarm all put back together and mounted on the bike....otherwise I would go check myself. Does anyone know off the top of their head? My bike is a 99 WR400.
