What kind of effects would i be looking at if my input shaft bearing went bad? I can't shift my car if i'm high in the rpm range, it works fine for daily driving but i can't shift when under hard exceleration. Also, if i'm cruising at 60mph, i can't downshift into 4th, it comes out of 5th fine but won't go into 4th, if i force it, it makes a bad grinding noise, it almost seems like i'm shifting without the clutch.

Any help would be awesome, i don't know if it could be the throwout bearing, input shaft bearing, or maybe a spring in the clutch disc that went bad?

please help

fi your isb. is bad i would make noise as you drive.
if the tranny grinds when shifting in the upper rpms, but its fine down low then it could be your synchros

I just get a funny image in my head when I think of that.

 

Bad throwout bearing: makes noise only if the clutch pedal is depressed.

Bad input shaft bearing: makes noise when clutch is released with the engine running. Does not have to be in any gear.

Bad output shaft bearing: makes noise only when the car is in motion. Same for diff carrier bearings.

Bad synchro: makes noise only when attempting to engage a gear. Rarely rpm related. You do have at least a bad 4th gear synchro. Check your clutch adjustment for the higher rpm shift probs in the remaining gears.

Bad clutch spring: doesn't necessarily make a noise, but could make clutch pedal appear to jam, depending how it fails.

 

bad clutch spring hella hard to put it into gear almost impossible it would start getting worse and worst until u just cand do it my springs fell out of the clutch.

 

thanks for the help guys, sounds like my clutch is shot...
