humming noise from my diff
2004 g35 coupe
when driving i'd say over 35-40 mph + i have this road noise or humming noise coming from i'm assuming my rear differential. at first i thought well its the tires but there brand new. and then the noise decreases as speed does and increases and speed increases.
what could this be a sign off? diff rebuild? bad diif oil?
i'd appreciate any suggestions. Thanks in advice

If it is the diff, do not waste your money rebuilding it. You can buy used ones for $300-400. I bought my 3.5 VLSD diff with 40k miles from a local auto recycler in Topeka for $300 and swapped it myself in 3 hours. It's easy. There so few rebuilders that can get the gears to seat right without noise and you can be assured it will cost you way more than $300.
