Rear end noise is driving me crazy.
It is not the tires, new ones put on 8 months ago.
Replaced left and right hub bearings 7 months ago. Noise went away. Now new noise sounds like it is coming from the differential.
Not much noise 0 to 20, gets louder after 20.
Any thoughts?
Thanks!

 

what kind of noise is it a grinding roaring screeching clunking

 

grinding whining

 

Does it vary with engine speed or road speed?

 

road speed

 

I'm wondering about your diff carrier bearings. They failed in my 300ZX and it rumbled down low and increased in pitch the faster I went.

 

Thanks for your responses. That is what I think it might be. Getting worse each day.
Any idea what it may involve and cost?
