Rear sway bar replacement

Quick question: To replace the rear sway bar do you have to lower the differential only or do you have to lower both the diff and the rear subframe?

Drop the rear subframe

Yes you must drop the sub frame. It makes sense to do solid sub-frame bushings and rear sway bar at the same time.

I honestly didn't think I needed adjustable sway bars but I did them when I was doing the sub-frame bushings since there was little, if any, additional labor cost.
