Ok, so a little background:
I just put in a 5.3L Chevy motor, replaced my frame, both axles (front D30 rear Ford 8.8), put in a AX15 and rebuilt my old NP231 to go to AX15. Novak products are sprinkled everywhere in between. The parts list goes on forever.
It sounds and drives like a monster truck.
I am honestly learning as I go here. I bought the transmission rebuilt from ebay (shame on me). The guy didn't put the bearing retainer on and I didn't notice after the Novak Adapter was on the transmission (again, shame on me). So last week I lost 4th gear when the input shaft pulled out. Immediately drove jeep home, pulled the tranny, and had a guy replace input shaft and anything else that looked chewed.
He had all the parts I needed in his shop. I wouldn't be surprised if they were used. Now that tranny is back in, Im getting a horrendous grinding noise coming from the tranny. It gets louder with speed and doesn't matter if the clutch is in or out. I can shift into all the gears, except reverse can be tricky sometimes. I'm assuming that rules out the throw-out bearing.
Could I have a bad pilot bushing or input bearing?
I know I can hear this noise from the transmission area. But for some reason, I feel like it also gets worse when I make sharp turns. Could it be a bad wheel bearing that just sounds like its from the tranny? Could it be both a wheel bearing and tranny?
Sorry for the essay. Since I replaced nearly everything, I don't know what to compare it to.
