I don't know if I should go though all the paint of replacing mine.
I went out and tried shaking/wiggling track bar on my truck and it didn't move but I'm pretty sure it's still original bushing in there.

 

What's the best way to get old bushing out?

 

The track bar I bought for my replacement didn't have a bushing in it so I haven't had to remove the old bushing yet. It looks like I will have to use a couple of big sockets and the vice like a bearing press.
The new neoprene bushings don't have the steel case around them so removal should be easy - they are in 2 parts with a steel tube in the middle.
