The pic above is from a current thread. Notice the bushing is not just deformed, it has worn away. Especially on the left hand side.
Once the bushing has deformed, it becomes loose in the torsion tube / cover plate. It then begins to slide instead of deforming to accomodate rotation (as designed).
Once the sliding begins, the bushing is toast. Wear becomes rapid, as shown. Corner balance slides all over the place.
Flipping the bushing to the opposite side addresses half the problem, at best. The "savings" vs new rubber bushings seems trivial compared to the labor and follow on cost of corner balance and align.
