I noticed about a week ago I was getting a strange knocking noise when slowing down to a dead stop. I changed my diff fluid today and the noise is 10x worse now?? It almost sounds like a flat tire flopping when slowing from 10 to 0. Any ideas?? It seems like rear passenger side but its only when I'm slowing down any info would be great thanks

 

is your tire pressure good?
cause um pretty sure your diff is going out

 

Yeah I checked the pressure today when I changed all the fluids in the car. I drove a couple of minutes again tonight but I didn't hear the noise?

 

brakes. Happened to me
