I noticed my car had a slight knock to it when I would come to a stop. It was only every now and then I'd hear it. I changed my diff fluid today and the car is 10x louder now it almost sounds like a flat tire flopping when I'm slowing from about 10 to 0.. any info? Thanks ahead of time

 

Strange.. drove it last night for a couple minutes then drove again this morning and didn't hear any noises...

 

Rock stuck in your tread that came free?

 

Ha no nothing like that it was coming from right rear passenger side. Maybe axle?

 

Can't imagine any thing like you described going away on it's own.

 

My rear diff made a noise similar to what your describing when my diff was about to go, lol, took diff out and pinion gear was missing two teeth....hope thats not it, just putting out there what happened to me.

 

Sounds like a diff.....bad bad experience. Get that thing checked.

 

^^agree^^

Was there a lot of metal on the diff bolt when you repalced the fluid?

 

No not much of anything just a light coat of grit, I still haven't heard the noise since I feel like I'm losing my.mind

 

Gremlin perhaps?
