hey guys I need help troubleshooting this issue.
Two or three times now the front driver side wheel has locked up or been very difficult to roll. The truck was skidding it was so stuck. The first time or two once I loosened the 17mm hex to take of the wheel off it freed up. (MIP X duty with 17mm adapters). Both times the inner part of the adapter (the part above) had come loose from the end of the axle. Last time I made super sure it was tight and the nuts were dead flat on the flat part of the spindle.
Tonight it happened again but the wheel was totally locked. I couldn't move it at all. Once I got the hex off and wheel the drive shaft still didn't even move. If I recal correctly the other times the driveshaft did move once I had the wheel off. All of the other three wheels moved fine still last night. So I tore it apart and once I got the diff open everything started to move freely. The diff is stock, but I run it hard with a 3800KV motor and 3S. I know tonight for sure I was really hitting it hard try to get it out of some deep powder (snow). Hard throttle then brake, then hard throttle. I'm sure that's what lead to the split of the MIP part. Still I'm confused what actually locked up.
I took the diff apart and the only thing I found wrong was part of the bushing or O ring was missing from where the output shaft goes to the side that was bound up. Now my gut tells me that little rubber part would have been mince meat and no way it could have locked up the wheel like that but I don't know. Other then that I don't know what it could be. Yes, I know XO-1 diffs would be good and I am going to order one. However for now I am going to rebuild this one with 50K fluid but I don't want to be missing something. Anywhere I should look or anything I should consider?
