I bought a set of front and rear differential bushings from a guy on svtp to defer the cost of my full bushing kit. Well I installed the front aluminum bushings today and it was pretty easy and straight forward. I have to say the first drive went well no more thud when going into gears the only extra noise I hear is a hum from about 60-65 any faster and it completely goes away. Also, the driveline vibration when on the highway at 80mph went away. I'm going to have to be careful with that as its more comfortable at higher speeds and I wont know my speed because its so smooth. I will be purchasing the rest and Bruce answered my questions promptly because I really wanted to do the rear diff bushings today but, decided to wait till I get the rest of the kit.
