This system cannot be driven without the drive shaft.
but you can try taking the connector off the rear drive module (rear diff) and see if that makes the noise stop.
what does the connector look like?
It is a 3 wire connector on the drivers side front area.
On the front area of the rear axle?
Or on the front area of the transimission?
yes rear axle not transmission.
Ok what does it mean if I do disconnect this wire and the sound DOES go away?
That will mean that it may not be as bad as you fear. Does the noise happen all the time or only when turning?
The noise happens all the time when driving straight.
Is this a common problem with the aztec?
The noise when turning is common but when driving straigh is not as common.
How bad is the noise?
with the windows up you really cant hear it but with the windows down it's a real loud grinding hum.
OK, does turning change it at all?
the noise isnt as bad when i turn left but is worse when turning right
Ok that sounds more like a bad wheel bearing than a diff issue.
I disconnected the 3 wire connector the noise disappeared for a minute but is still grinding.....it is not as loud as it was.
if the noise is only in the rear diff, then my suggestion is to drive. The rear diff is a replacement only so if the noise is in there, they will replace it anywya.
drive with the connector disconnected?
Yes, if that makes it better.
Okay......THANKS...appreciate the help!!
MY pleasure. drive safe.
