1989 s13 hatch red top sr20det

yester day my car started making a whining sound ONLY druing accel. when clutch is in or in neutral it makes no noise even if i rev. but when im in gear the noise gets higher pitched as my rpm's ramp up. i have done some researche but just wanted to get a seccond openion on what this might me... through out bearing? input/output shaft bearing? cluthc? low oil? im gonna drain and change my fluid sometime this coming week

thx alot for your help

Does it happen in boost only?

[maxgohan]

maybe the diff?

[SilviaAura]

it happens the loundest around 2k-3k rpm... my friend who is a tech said its possible to be the throw out bearing...does that sound like it?

[ch1873857]

throw out bearing is only engaged when the clutch is disengaged. Bad TO bearings start making noises when the clutch is disengaged. never heard of one making a "whining sound as a accelerate."

if the noise occurs during acceleration it may be a gearing thing. whether it be trans or diff. had a bad diff one time that whined on decel. hope it helps.

first things first, do a good PMCS. fluids, belts, etc.. cheapest thing first.

thx ch187... i'll try to do diff fluid first. dounbt its my tranny.... i hear it form the back of the car...at first i thought it was my rear bearings but its not them... it probably is my diff

Could be diff or a bearing on the transmission somewhere.

+2 to the possibility of it being bearing
