Well this is what happend
I was driving my W126 SD...
and i heard a pop..
looked under the hood and pulled a broken AC compressor belt.
Next day.. dricing heard a squealch..stearing went outand sounded like a bird chirping..
looked under the hood and there goes my belt to my power stearing.
also noticed that the 1st belt to the altinator was gone aswell. although the 2nd one was running it fine.
Now.. i when i start the car it squeals for the first 500-1500 rpm.. but then it goes away.. what could this be whats causing all of this belt breaking and squealing?
