Front end question

Hi, I have a 97 TC that is having some squeaking in the right front area, I have pinpointed it to the upper control arm bushings, what I want to do is spray some lube on there for now, does anyone know if grease or silicone would be best used in this situation, thanks

Not a solution but a warning. I had a 96 TC with some noise in front end and I shot it with WD40 for a couple weeks. Did great until I dropped a balljoint at 50mph. Don't mess with it, just change the worn part. It is squeaking because it is most likly wearing/wore out. Good luck!!
