Hi all I’m new to LC community and need some advice. I bought this 1973 FJ 40 a few months ago and since then it’s had a bad vibration from the driveline. It’s a small block Chevy conversion with a 700r4 AT. It was a good restoration from what I can tell and Everything seems to have been done correctly. I pulled the rear driveline off down to the output shaft bearing. There seems to be some play in the bearing. I’m assuming there shouldn’t be any play there? It looks like the bearing is pressed in and I’m wondering if i have to remove the TCase to replace it or if it can be removed in place? I’ve seen all the threads I can find on driveline vibrations and have narrowed it down to this bearing.
