Does anyone know if the nut holding the companion flange on to the trans is a one-time use nut like the axle-nuts? Is there anything other that I need to replace when changing the flange or is a new seal the only item I need? Thanx.

 

I have reused this in the past. It all depends on the stake area. I found when I changed the flange that the stake area was differant. I.E. a new area was available to stake.
