my PST Strud rod Bushing Fell off the car! *PICS*
You can only cup them correctly with the original style tapered washers and bushings. The radius washers should not be put on in the opposite direction to cup the bushing . The inside diameter is smaller then the outside of the bushing.
And the problem shouldn't be PST's. They only lasted about 4 years when these cars were new. And then the washers were installed correctly.
