'I'm 100% stumped. If you remember right before I put the car away for winter I had a grinding sound coming from the car...was a faint metal on metal sound, like metal rubbing against another piece of metal while rotating...similar to that sound you get when you go over rumble strips, or when they've stripped that first layer of pavement from the road and you drive over it...but the sound is obviously quieter.
Anyways mechanic said rear sounded quiet...but the tail of the trans was grinding...fast forward to today, I've swapped trans and still have the exact same sound.
I thought the DS might be rubbing as there is marks on it...so I just put painters tape on the shaft where the marks are to see if it was infact the issue...tape is untouched.
Wheels don't look like they're near anything to rub, and I've swapped the rims/tires to eliminate that...still nothing.
I'm stumped...what the heck else could sound like it's grinding? Seems like you can hear the noise sometimes on accel, sometimes on decel...and the odd time if you put the car in neutral and rev it...all instances seems to occur with extreme light throttle, at higher throttle I'm sure its blended in with exhaust/motor noise.
Who has ideas?
I've pulled the belt and spun the pullies, most noise I hear is a squeaking
Alternator pulley.
Tires all turn freely, no marks on the rotors..I'm 100% out of ideas...I thought maybe even the timing chain, but my KR sensors pick up 0.1-0.5 degrees of knock at best and its random...and not usually when I can make out the grind/whine.
