Hi all. My 96 is starting to show it's age. Recently the front suspension squeaks when it flexes with regular driving and when I push on it up and down. I've isolated the noise at the lower wishbone pivot bushings on the car frame. The noise is getting really loud. What is involved in replacing these? Are any special tools needed? Can I do this myself or do I have to take it to a garage? Generally, what would the job cost? In your experience, is this a part that goes bad at 70K or is something else wrong? Can I just shoot it with some WD-40 and hope for it to go away? Thanks very much for your help. -Brian.
