OK, the lower front ball joints on our 90 have some play in them. We need to drive the car 300 miles (round trip) on the interstate this weekend. I know it's not the safest, but in how much danger are we in here? How often do mk3 worn ball joints blow out? I just blew a Ball joint on my 4x4 offroading this weekend so I'm kinda paranoid now. what do you guys think?
