So we got the car up on its side(one jack), the wheel off ect and the friend I've got working on it with me says that he wants to disconnect the halfshaft from the diff. From charlie's post it looks like we don't have to do that. From what I can read, we should essentially lower the entire rear "assembly" meaning:

Hub - Trailing Arm/Halfshaft - Diff - halfshaft/trailing arm - Hub

Once thats done we should be able to replace the trailing arm without disconnecting any of the axles.

Do I have this correct?
