A4 ABS Update.

[Bob]

It was about 60 degrees here today so I went out and worked on the pig.  
Thanks to some advice from folks, I put the oscilliscope on the ABS 
Sensor outputs. 3 of the 4 looked textbook perfect. The 4th (right rear) 
was pretty noisy and dirty. I assume that was the one.  So I took the 
output of the left rear and jumpered it to the right rear harness and 
all was well.  So now I determined its the right rear, and likely the 
gear in the CV. (it appeared scored)

The next question is, any BTDT's on replacing the gear? Would love to 
hear war stories....  Probably wont bother with the sensor at this 
point, its easy to replace.
Thanks in advance!
