Broken track bar bracket

[t8er]

Debating with my buddy on his TJ. He's got a pro Como lift. 3" I think. Would a busted track bar bracket on the axle cause driveline vibration. He says yes and that its pinion angle. I realize pinion angle can cause it but I think it's the bracket because up until recently there was no vibration.

DW if on the front. Does he have a SYE/double carden shaft or TC drop ?
Sounds like DL vibe to me.

He has the transfer case brackets.

Front or rear on the track bar bracket ?
