So I replaced all the accessory bushings on the last TB change, but the alternator bushings aren't lasting very long. Happened on two cars, the symptom was squealing alternator belts out of the blue, the bushings were cracked and falling apart. Recently replaced them on brick 1 (93), bushings were three years old. Now brick 2 (92) has the same problem, bushings are 2 yrs 10 months old. They are the IPD blue poly type. I am getting ready to do another TB change on brick 1 and have some more poly bushings ordered (maybe I'm a little slow...). Any ideas? Thanks!
