Hello,

I have been hearing an increase in this sound from the rear. I have had the car for only about two months and you can really only hear this well with the top up. That being said, I changed the diff, tranny, clutch, engine oil, everything about 4 wks ago... so don't know if any are the culprits... I used Valvoline synthetic 75w90 for the diff.

I am not sure if it is the diff or driveshaft. At the driveshaft's connection to the diff there was an oil/grease splatter area since I bought the car, I do not know what it is from. There are no leaks and no other issues...

This "thrumming" sound increases as speed does...

Please help diagnose this rear end / differential / driveshaft noise.

I would be looking to buy these used replacement parts (WTB) used from a low mileage car, in case you know of one. But first I have to know what to buy!

thanks!
