<VV> Early halfshaft wear mystery

[jvhroberts at aol.com]

 You may want to check the bushings, mounting hardware, engine mounts, etc., as well as anything bent to see if there's anything allowing misalignment of the axle, allowing rubbing in certain parts of the suspension travel.

Subject: <VV> Early halfshaft wear mystery










Today on my way to work, after a swift right sweeper and just as I straightened 
back out I heard a squealing noise from the Left rear wheel area. At first I 
thought the tire was rubbing, but I could find nothing close. The noise 
continued intermittantly, seemingly making noise on left turns (or when there 
was thrust that direction) and going away if I turned right. When I got home I 
inspected the axle and found a shiny worn band about 3/8 inch wide on the axle 
shaft. The worn area is at the left (outer) end of the opening in the rear of 
the A-arm for the axle exit. See the photo here:

It looks like recent wear, almost like it was turned on a lathe. But I could not 
find any corresponding shiny spot on the A-arm. I have the axle out now, and 
partially disassembled. I can't figure out how it got the shiny band. There does 
not seem to be enough slop in the bearing or U-joints to actually allow contact. 

?
Has anyone seen this before, or have any ideas I have not thought of?
?
Thanks!
