The spring plate bushings are intended to "squirm" internally. If
they slip, either inside or outside, they will wear and fail. The
squeak you're hearing could be from slipping, or it could be from
metal to metal contact somewhere.
As Keith mentioned, the OE bushings are a real bear to install,
because they are so tight. I suspect that the polyurethane
replacements are made slightly smaller, so they will be easy to
install, but that makes them likely to slip and wear, so I'm
skeptical about their long term reliability.
In 45 years, the ONLY diagonal arm bushings I've ever replaced were
on one side of a '71 squareback where someone had removed the pivot
bolt and neglected to put it back. Left unconstrained for years, the
bushings ran into something else and got distorted to the point where
a replacement pivot bolt would not go in. I had to remove the old
bushings and install new ones to restore the rear suspension
geometry. The owner admitted that this quieted down the ride
significantly, now that the diagonal arm was no longer banging around
back there.
In other words, I doubt if there's any problem with your diagonal arm
bushings, assuming the pivot bolt is in place.
