look at the hubs, the splines should not be sharp, that's a sign
they are worn.
My first thought was U-joints. I had that very same cluck on
my 510 when I first bought it. It was the left rear inner

Sounds like grounding issues. But I bet Paul Hunt will
have words of wisdom. You can cut to the chase and
go to his web site, and look around.

Also Paul Tegler's site is a good resource.

Skye's excellent site http://www.mgbexperience.com/
Chicago Land MG, could also help. And Barney's A

Sounds like you are on track on this one already. It may just be
worn and loose.
