So say a have a squeak at low speeds either reverse or forward and goes away after the car speeds up... could I assume that is in the drive shaft? It isnt a constant squeak and definately sounds like its under me.. It starts out slow and then speeds up until its gone... about the same tempo as the standard bomb beeping in movies.. It hasnt affected performance but is annoying.. Any guiding words? could it be the U-Joint? Some bearing? I also thouroughly greased all points...
