Are rotaries suppose to "whine"? While the car is under a load it's pretty loud, push in the clutch and the sound decreases dramatically but I do still hear the rear end but it's faint. Any idea's?

Thank You,

 

No they aren't supposed to whine. It sounds like it's coming from your tranny or differential.

 

I would have to say the diff, but my second and third gear syncros are going out. Mind you the car has 180xxx on her

 

Does it whine when you are in 4th gear?

 

It whines in all gears, gets a bit louder in fourth and fifth especially going up a hill. (I live in the mountains)

 

my 83 gsl whines pretty good,do u have stock belts?mine has a afetmarket belt wich is like 2 inches wide with the grooves in it so its pretty normal for a big belt like that...

 

It's going to be the trans or the diff.

 

Synchros don't whine. Gears can whine. Bearings can whine.

Change the gear oil on the trans and diff. The one with lots of metal fines is the whiner.

 

Thank you

 

my fc whines but its because my throwout bearing is getting bad might want to investigate that too.

 

I would suggest checking the fluid levels in the gearbox and diff.. replace them with good oils if they haven't been done in a while, it can help extend the life and also help in reducing any whining.

 

Mine whines a little, not too bad and nothing that I can feel is wrong.

 

The best way to get rid of the whining..leave the girlfriend at home.


I would change the fluid as recommended^^...It's most likely a bearing...are you getting any harmonic vibration?

Has anyone taken off the front pulley hub off the e-shaft recently?

 

redline mt 90 is supposed to help with that...

 

5th gear in my car is super loud
