update
i found a turbo today, that is the upgraded turbo for my year model.
alabama diesel injectors & turbos in henager, al
the ford dealer list it at over 1400.00, will sell to me for 1100.00
this place in henager, al will sell it to me for 950.00 plus tax (you can do the math.)
he did tell me to make sure the boots, clamps are all good. he said a bad boot will make the squeelin noise too. also to take of the air intake connected to the inlet of the turbo and move the wheel around from side to side and rotate it, to try and see if it will rubb up against the housing.
if it does, then the turbo is bad.
gonna get into it tomorrow. wish me luck.
