Have a 1983 Schaffer and Sons 53" upright - all action centers are tight and they get worse with alcohol water treatment. Is this the Young Chang contaminated bushing issue? I think it is made by Young Chang, not certain. Is there a remedy other than repinning or parts replacement? Is there any hope for help from the warranty/manufacturer?
