rear end noise

[blue_malibu]

my 2000 c5 coupe has a rear end noise every time you turn right .i have had fluid changes twice at the dealer but still the same.they put in one additive the first time,two additives the second time but did not help. any solution?

[aquaholic]

what kind of noise? grinding, ratcheting, growl, howl, whine? the more info that you post the more someone will be able to help.

it is sort of like a ratcheting noise like gears or splines are not meshing. hope this helps

Did you drive the car in a series of figure-8s, forward and backward (in an empty parking lot) after the fluid change?

Is this on all right turns? Or on tight turns, slow turns, etc.?

I'm guessing wheel bearing

[blue_malibu]

happens only on right side

HI there,
Please have them install the CORRECT FLUID< DEXRON LS and your problems will be gone.
No additive is needed ONLY THE FLUID>

wouldn't the noise happen in both directions if the fluid was wrong ?

In my limited experience , when the noise happened turning right , the left bearing was bad and when turning left , the right was bad.
I've changed both over the years and this was the way it happened to me and others who have dealt the similar problem.

but , without hearing the problem , my online diagnosis can be off
