[s-cars] rebuilding axles

[michael musmanno]

hey guys,

I was wondering if anyone had any information about rebuilding axles.  I 
have a spare set of front axles for my '93 s4 that i'd like to rebuild 
and put on the car.  what kits do I need to get and where do I get them 
and are there sites I can go to for instructions?  all the information 
available is greatly appreciated.  or, is there a site to buy already, 
professionally rebuilt axles?  cost differences relative here.

thanks
mike
