<VV> differential questions

[BBRT]

Ken Hand drills a hole in the pinion shaft so I suggest you contact him at 
vairmech at aol.com.

The in and out movement of the yokes is probably ok for the street and some 
say due to loading characteristics on the suspension, won't affect much. 
For precise work, you can make a shim to tighten them up a bit. The nuts are 
hard to come by and I doubt they have worn much. IMHO, it is the wearing of 
the cross shaft in the carrier that holds the spider gears. If you think 
about it, there has to be some slop or clearance in there. If you are using 
a four spider block in the carrier center, then you may have to grind the 
nut for clearance.

Again, I wouldn't worry about it unless you really think it is excessive.
