My E320 has been getting kind of wandery, and last time I had it up on the jacks I noticed there was some lateral play in the steering.
What should I look for to figure out which links are bad and need to be replaced? I can't afford to shotgun it and buy one of everything right now, so I need to be able to triage it.
