I just had the new rear bushings from Volvo put in with an alignment. I don't know if it's better or worse. Straightline seems better but turning or changing lanes seems jittery.. The alignment is fine. Trouble is I also went to the Goodyear F1's as well, running them at 36-37 psi. Anyone here, who has done the rear bushing "Fix", have a positive or negative opinion on it? It's been suggested that I play with the tire pressure as well(39-40 psi).
