I think my S197GT suspension is in need of some maintenance at 160k. However, I am not sure where to start. The front end clanking has been there from the very beginning, per TSB ( strut mounts I think), and I think I am noticing some other noises. What would my course of action be? Miles are all highway...

 

At 170k my new edge was getting pretty worn out also. I ended up upgrading everything but if you aren't replacing any major components I would start with all new bushings.

 

Struts, strut mounts, swaybar endlinks... maybe front arms and ball joints.

Rear control arms, swaybar end links.
