yes the t-case needle bearing failure was due to lack of oil. However that has been a lesson learned. I did check my pinion prior to reinstalling my third as well as it installed for excess play and found it had no more play than it did when it was setup from marlin. I thought about the drive shaft phase but figured since it was on the balance machine yesterday and was nearly perfectly balanced and I didn't pull it apart it would be balanced when I reinstalled it. Is that incorrect?
