Rear Trailing Arm Bushings question Options

[Bates]

I'm replacing the rear bushings and want to allow lubrication via grease fitting.

Do the inner diameter of the bushings pivot on the shaft or do the trailing arms pivot on the outer diameter of the bushings?

Bushings seem tighter on the shaft, and that surface area is much smaller than the o.d.

Bushing is supposed to rotate on the shaft.
Bushing is supposed to be fixed/attached to the trailing arm.
Bushing is not supposed to rotate in the trailing arm.

Hack?
Well, if the bushings are aligned by the pivot shaft and the epoxy allowed the bushing to be perfectly self align and then that same epoxy keeps them perfectly aligned and 'fixed to the trailing arm i.d., I do not see that as a 'hack'.

I see the method as the correct way to install bushings that keeps the bushing from rotating in the trailing arm and also keeps the bushings aligned and will do so in the future, which will result in the bushings lasting longer.

I use the same method for the front suspension, and sway bar pivots if the bushing has any tendency or probability to be able to rotate in the bushing holder (what ever that may be).

Suspension moves freely without and binding, and that is the ultimate goal.
