My 72 mach 1 makes a noise in the front passenge side I had it on a lift, noticed the lower control arm bushing was bad so I replaced the entire upper contol arm(lower ball joint and bushing) so I took it out for another test drive same noise so I replaced the upper ball joint but not the upper control arm bushing test drove again still the same noise the shocks appear to be ok, what else could be the problem?
