You will probably need the alignment checked again as the rear toe can change with the new links.

Replace the subframe bushings and all links including the rotating ball joint bush that the lower spring support connects to (it takes a few bits of pipes and a threaded rod to remove and install)

When you tighten the units up - make sure the drive axles are sitting exactly straight - This is normal riding condition for the bushings - test drive and feel the amazing control of the 5 link suspension. It makes the car a MB.
