Hi, long time lurker here - Having some issues with my new to me LS1 swapped 240Z. I believe it’s got an R200 mated to some ‘83 ZXT half shafts. In the passenger (LHD car) rear I’m getting knocking over bumps, around corners and driveline vibration above 65. I’ve taken the rear suspension off and that same rear passenger side makes this noise when rotated: https://imgur.com/a/MtrFoFS I do the same with the other side and it’s quiet. I guess first step is to swap the shafts left/right to see if the noise follows? If so that rules out the diff. Then it’s whether I can source replacement half shafts or get these rebuilt..? Any input appreciated.
