If the upper a-arm is knocking about it means that UCABs have
developed enough play to allow too much movement which could
with time disfigure or stretch your upper control arm (UCA).
Then when you attempt to replace the UCABs you might have
difficulty getting the long bolt in which cinches the UCABs
along with UCA and you might be SOL or SO$, IMHO, LOL, ROFL,
BYOB, etc, which might require a good used UCA or a BFH to fix
the existing one.
