91 GSX, I have never been into my tranny. Its obviously time but Id like to know whats going on and what I will need. I plan on rebuilding everything but Im on a budget at the moment.
For about 3 years now its made a noise on decel at highway speeds, as soon as you give gas it goes away. Its kind of a metal rattling, and you can feel it also in your feet. It hasnt really gotten worse until recently, and what I hope is related is Ive been fighting some phantom knock for about a year, down low 2-3k, even does it on free revs. I hooked up a stethescope to listen, and in the bellhousing area theres a definite wirring noise at idle, and when you rev it itll sound really horrible with the stethascope on... like metal hitting on metal. When you push the clutch in and put it in gear and rev it goes away, and it is not I REPEAT NOT the throw out bearing. Also my transfer case is untouched and stock, and theres play in it. With the car in the air the wheels can turn a 16th before the driveline turns. Thanks in advance guys
Sounds like input shaft bearing, no thanks to the input here
