I found I had a very significant shake on my BJ-8 when driving fast, about
75 or 80 MPH. It felt like the rear end was bouncing up and down - in a
dramatic fashion giving me a pretty good scare. I typically don't drive
that speed, and owned the car for quite a while before it showed up. My
first thought was I was getting a flat tire, but as soon as I slowed to 70
MPH or so the shake stopped and I continued on my drive. Afer assessing my
options, I sent my drums to Hendrix. They indicated both drums were
significantly out of balance. Upon installing the newly balanced drums, the
shake disappeared. My car has never driven more smoothly - even noticable
at slower speeds. Just a highly satisfied custer........
