Close-up pics of bad control and thrust bushings (warning: 400+kb)
Here is a close-up of the old thrust arm bushing. This bushing was allowing excessive movement of the thrust arm leading to bad tracking (tramlining). It's certainly not obviously bad via the visual inspection. If you look close, you can see some very slight tears in the rubber but that's all. Pretty interesting.
Here's the control arm bushing. Wear's a little more obvious here. I don't think you could have seen this with the bushing installed as it's covered but the chassis.
Hope this helps others assess the conditions of their front end.
