Hey I had a machine shop put in my new bushings and I am putting the upper ball joints in now. If I clamp the shaft in a vice and turn the arms they squeak. I looked at the bushings and I can see the grease has been applied (I asked them to do it they say they did). Are they just squeaking because they don't have any load on them? Or should I take this as a problem and not reinstall them? Thanks for all the help on the previous posts.
