I am working on replacing my control arm bushings and I have found that Ford used standard bushings and hydro bushings. I have read many different things on the Hydro bushings. I have not been able to find any information about if I have to use the hydro bushings or not. I haven't checked to see which ones I have yet and I am wondering if it manners or not. If I don't have hydro bushings can I get them installed in the control arms. I have looked all over the internet and I have not been able to find out this info any and all info would be helpful.
