Hi, I am thinking I will try replacing the nearly 20 year old carrier bushings in the rear as I am thinking that the old, now hard, bushings are transferring more noise than a new set might? Ideas?

Yea, saw that and read up, I did just see the “in vehicle” ring and pinion repair section, not sure if this actually can be done?
I believe it could be rebuilt in-vehicle but it's only held in by 3 bolts so I see no reason to do that.
