I've suddenly picked up a vibration in the left
rear at speeds above 70mph; usually starts on staights rather than curves. Don't appear to have tossed a balancing weight from the wheel. Dead strut? U-joint? Other ideas...?

Any dried up mud on the inside of the wheel can cause it. But that would apply more to 4X4s. Does any one knoe if loose wheel bearings can cause this? I need to tighten mine, they are a little loose. At over 60 I get vibration which increases as I speed up.

Don't get to tied up on a single wheel, high speed vibrations can come from just about any were. I would start with wheel bearings then check half shafts and diff. mounts. Struts could be the problem but they would have to be pretty worn and you probably would notice the bounce by now. You might also check the tires for a broken side wall belt.

before you tear your car apart spent twenty bucks and get the tires rotated and balanced.
