can i replace the bushing balljoint looking thing on my track bar. not the part that bolts to the axle but the side that bolts to the unibody/frame mount. i can get a whole track bar for $40 but if i could fix the one i have that might be better.(it is already the right rust/mud color....lol)

 

I'd say just replace it. Whenever I have to replace something, I take that as an opportunity to UPGRADE (although I'm sure you don't want to go that route). With a stock track bar, you can't just replace the tie rod end (it is fixed in the bar), so you're gunna have to replace the entire thing. But when you say "balljoint bushing", are you talking about the tie rod dust boot? That's definitely replaceable for a dollar or two

 

upon closer inspection it is not just the grease seal i need a new bar but thanks anyways the reply is appreciated.
