Maybe someone can give me some ideas,last year i replaced my driveshaft, had one made for the car from a reputable place , then i bought a new third member for my 8 3/4 , 3:91 posi, again from a reputable source , went through his breakin procedure to a tee. Installed the stuff last year but last night was the first time i attempted to take it on the highway, once i hit about 49 mph, crazy loud humming sound, hard to explain!sounds like something gonna let go
