Well the WWS was replaced.
The shop still had the OEM hubs I took off & he took the sensor out & put in the new hub. All is good on that. All the loud popping & knocking sounds were the trackbar was loose and that was re-tightened. The strange noises I was hearing from under the XK was a few items. The 4x belly skid was tapping the cats, resolved & the front diff was coming in contact with exhaust, will have that dippeled.
All that is left is a new DS and Rear UCA's & some more trimming to prevent rubbing from the tires.
All and all I have happy again on how this is coming out.
