Hey guys, I got a high mileage 140k 99 z28 6speed. I have a few thots but dont kno the real problem. Heres what it does. At idle in nuetral, silent. when in gear driving, makes a whuuurring sound that gets louder with rpm. No matter what gear same sound, louder with rpm. Push in the clutch, dead silent again. At any speed, any gear- it goes dead silent when you push in the clutch... All stock btw. What do you guys think?
rearend.......
Yup, my guess too. Just had mine rebuilt for the same reason.
but if im goin along at any speed, say 40mph and i push the clutch in, theres no sound from anything. not the rear, not the tranny. silent. then when i take my foot out of the clutch and it engages, it makes the whurring sound.
Does it sound like it is coming from the engine/tranny or the rear more?
really sounds from tranny. bellhousing area
Sounds like it could be the throwout bearing or pilot bearing.
It probably the input shaft bearing
