Hello All,
I just aquired a '91 Eagle Talon Tsi AWD Turbo and it drives fine but when I let off the gas to stop at a traffic light, I here a whining noise from the rear of the car. The car has 99,000 miles on it. Any thoughts? Thanks! |

are you down shifting when you hear the noise?

If the factory gear oil is still in there you should probably change that. It can't hurt.

QUOTE (mitsu90 @ Sep 30 2004, 08:20 AM) are you down shifting when you hear the noise? Nope not downshifting. It does it in every gear while decelerating though. If I push the clutch in it goes away completely. The car runs and drives 100%. No grind in transmission at all. |

sounds like a rear differential stress-load related problem

Well, does it make the same whine noise any other time? Rear diff gears that are cut a certain way can make more noise than normal. Ever ride in a H0nda when it's backing up and listen to the whine? Make sure the diff isn't leaking or out of fluid either.

Ever ride in a that other car that we shall not name when it's backing up and listen to the whine? Make sure the diff isn't leaking or out of fluid either. I don't hear it any other time. It's only on deceleration. |

Reverse gear in almost all modern manual transaxles is straight-cut, meaning there is no slant to the teeth. That is what makes the whine in reverse. Straight-cut gears were in the late 60s Muncie M22 close ratio "rock crusher" transmission. It got it's nickname from the agricultural whine it made in all gears.
