[TR] List diagnosis requested TR6

[Bob Danielson]

Ed,
Can you better describe your inspection of the diff mounts for cracks. It 
doesn't take much of a crack to cause the dreaded clunk sound and it isn't 
always very visible. I had the clunk and couldn't find any cracks until I 
took a wire brush to the mount and really cleaned it up. Even then, what I 
saw surprised me that it was considered a crack as it looked more like a 
thin line in the mount. There's a couple of pictures about 1/2 way down this 
page http://tr6.danielsonfamily.org/DiffMounts.htm
