not sure if it's the diff, i just have suspects at the moment... still trying to solve the LOUD
hum originating from -what seems to be- the rear passenger wheel area. KoupeKrazy can back me up on how rediculously loud it is. and to be perfectly honest it's gotten to the point now where I'm not willing to ignore it any longer.
It's not wheelbearing (already replaced that)
hum volume rises & falls with travel speed, but exhibits no apparant or associated vibration whatsoever.
thinking of replacing the entire rear-end... Diff, axles, everything. Reseal and regrease everything as a preventative measure and then see where I end up.
check yah later

good description vvvv
best i can do. i've brought this thing up numerous times... guess nobody cares enough to remember my goings-on.
year and a half ago i thumped the Pax rear wheel into a low curb (snowy parking-lot action), but not very hard. ever since then it hummed very very softly... i could barely hear it at any speed for months, but it did gradually grow louder and develop more defined pitches at various speeds. Now it's to the point that i can't hardly hear the engine, i can sortof hear the exhaust, and I have to turn up the stereo a bunch more. Also impinges on rear-passenger conversation.
replaced wheelbearing as a measure towards fixing the hum, but that did ****all. I'm thinking that when I initially side loaded that rear-corner drivetrain it either pushed or bent something ever so slightly out of wack. that's why it was so quiet 18months ago... and now Thousands of kilometers later it's been wearing & tearing and becoming louder.
thoughts? ever heard of this before.... is there a precedent for a defined rear hum. I had heard of "old Audi rear differential hum" before but wasn't sure if that was my case. In any event everything seems to stem from me side-impacting that rear corner, and so now I haveta fix it before I go up to Northern Alberta where NOBODY has ever heard of Audi =(
