Okay so I have my t100 lifted and I put a brand new carrier bearing on it when I did the lift because the old one was completely done. The guy i bought the truck from gave it to me so I dont know where he got it from. 1 year later that carrier bearing was done. The truck started to shake extremly bad. I bought a new one from NAPA and that only lasted one month. It would squeal really loud and it started to shake again. So I went back and they replaced the part. Once again the carrier bearing is squealing really loud and starting to shake. Does anyone know what I should do. Im starting to wonder if it is NAPA or if my driveline is out of wack or what is going on.
