I've read this post a couple of times and it still comes back to me that " I " would have this checked out completely, before not only endangering your own life but the lives of others on the road also.

Not sure where your located but, if you need help locating a competent mechanic I'm sure someone on the list can help.

To many variables to go wrong to see you hurt yourself, someone else or your vehicle.

Good Luck,
Mike
