If I am replacing the trailing arm bushings do I really need to Loosen the drive axle nut? most post and bently seem to indicate to remove the drive axles at both the diff and the wheel hub, Is there really any need to remove the axle at the hub? why not drop the trailing arms with the outer axle and components attached? thanks!! note this is also posted ander the subframe removal thread but re-posted here as a unique thread.
