Anyone ever seen this? My 2001 Deville had a leak under the left front suspension last night, so I took a look...seems to be coming out of the front lower control arm bushing. It's a black liquid with thin consistency, and it's not brake or tranny fluid...could be old lube I guess. The top of the bushing and the area around it was dry, so I'm fairly certain it came from the bushing itself. I cleaned everything up to see if it was still leaking, and today it's pretty dry. No change in drivability that I can notice. Did this stuff come from the bushing?
