I need some expert help. The gf has a roar coming from the rear end on her 99 WJ - I'd like help her out and see if it's as bad as she has been told. "Shop" says that she needs a completely new rear (hers look amazing to me :laugh: haha...) but I don't think so. It's a Dana44 with 3.73 the limited slip. At speed there is a roar, very noticeable that increases in volume as you get faster. Sounds just like very aggressive tires, but she just has mild Bridgestones. I pulled the cover to change the oil with 80-140 LS additive, and there was some metal on the magnet, and some in the oil. I dont' do gears much, so i don't know what is a "normal" amount of metal. The ring teeth are smooth and sharp, not worn over, and there are no chipped teeth on it or the spider gears that I can see. It had been leaking she says, but I dont' believe it was really low. I was thinking she needs new clutch packs in the carrier, until i noticed the passenger rear wheel has goo in it from a fluid leak. Couldn't check that as she had to leave for work. Would a wheel bearing make this noise? leaking seals cause other issues? Thanks for the insight.
