is it the drive line or the dust cover.
dust cover is not so bad, if the drive line bottoms out it pushes the cap out of the end of the drive line any ways.
it is kinda messed up that that front moves closer on compression... vs the rear that moves away on compression.
I am looking at the square ag shafts....

also thinking about the 6 sided steel shafts and a 6 point deep well socket..
