I think the tie rod ends will be fine. One of them is bad and needs replaced. I have noticed that the solution had alot of grease in it. I used a whole gallon to do these and am soaking more right now. Its pretty dirty, so I think you should spend quit a bit of time cleaning with Mean Green (i get at the dollar general along with $1 cans of oven cleaner). I didn't get the tie rod end sleeves clean enough before derusting.

This is what I have soaking now.
