One of my rear tie rod ends appears to be worn out. I know of at least 2 others who have had to replace theirs. I first noticed the car darting around a little bit and began checking things on the front suspension where I suspected the problem was. But everything in front was tight and it was a few days before it occurred to me to check the rear. I'm curious if anyone else has had to replace these. Tomorrow I'll check with Tesla for replacements.
