About 5K miles ago, I was hearing a creaking noise from the left rear of my TE. If I sprayed silicone onto the spring link (trailing arm?) bushing, noise went away. So bushing is deteriorating.

Recently, I noticed abnormal wear on the outer and inner edges of the left rear tire. Tire pressure ok, and other three tire wear normal. I removed the wheel, and the left wheel carrier bushing looks bad, with badly cracked rubber. The rubber on the other four suspension links look ok.

I suspect both of those bad bushings affect the camber when the car is in motion, and causing that abnormal tire wear.

I do not have the correct bushing extractor/press in tools, so I may buy a complete spring link (trailing arm?), and take it to the Indie to also replace the wheel carrier bushing
