I have a wobble my car aquired after my swap, got aligned and balanced but it never fixed the problem. It rode fine before so Im thinking its in the drivetrain. I got under the car and shook my driver side axel where it connects to the half shaft and it moved up and down about 3mm and in/out bout 1mm. Should that play be there or should it be rock hard? Do half shafts go bad? The wobble comes and goes and starts around 50-60.

 

TTT, Need yalls help on this one.
