What are the symptoms of a bad Input Shaft Bearing? Where is it located, and how long will it last? Because I put in a tranny I got off of craigslist and it makes a horrible gear grinding noise when its under load (slowing down in 1st/2nd gear) or accelerating full throttle. It drives fine and the clutch grips fine it just makes this noise. And its not when going into the gears, it shifts like butter. So I'm just wondering if its the input shaft bearing, and how hard it would be to replace this.

 

Idle the car , step on the clutch. than listen while you let it out , if it starts whirring , its mainshaft bearings..

 

it doesnt whir when you let it out. It grinds when under load

 

any more input here?

 

have you ripped it apart yet man and checked it all out or drained it and inspected the oil from it?????

 

no i have no idea how to take the tranny apart. Or if I take it apart how to put it back together lol

 

e either till 2 weekends ago man i followed a tear down thread, and couldnt beleive how easy it was.

my tranny has been making a metal on metal squealing sound like a bearing going out so i took it out ripped it apart, and found all kinds of goodies inside it (broken gears,metal peices).
