5ktq massive vibration from rear 20-40mph

[Joshua van Tol]

Bent wheel? Broken cv joint? Unbalanced wheel? The rear diff could be  
bad, but I doubt it. If you want more data, drain the fluid, and see  
if there's any chunks. There will probably be some metal filings in  
the fluid, but there should be no chunks.
