Differential whine

[PBR]

Dealer replaced both rear wheel bearings, but still have a whine at 62 mph with foot on accelerator, not quite as bad at higher speeds. Met with Isuzu factory rep, he says its normal, I have driven two others that dont dont have the same whine. Need testimonies from other owners to convince Isuzu to do something Help!

TOD is still the more likely candidate in my experience..... add a switch to interupt the blue/white wire and see if the whine goes away.

Thanks Tone, but noise is coming from rear end behind the back seats, could that still be tod?

Have an independent rear end shop check it out if you are still concerned.
