I will have to check that! I just changed everything from the inner-C out balljoints, shaft joints, all seals...etc and I still get the thud under the floorboards.
But yeah in the authors pic it definately looks like your inner axle seal took a poo. That could have worn out because of some play moving out towards your ball joints or somewhere else? just my 2cents.
